TITLE: A CONTRIBUTION TO THE DEBATE OVER THE ORIGIN AND DEVELOPMENT OF TREPONEMAL DISEASE: A CASE STUDY FROM SOUTHERN ILLINOIS. MAJOR PROFESSOR: Dr. Susan M. Ford There is a long-standing debate over the origin of syphilis, one of the treponemal diseases. Some researchers believe syphilis originated in the Old World but was misdiagnosed as such diseases as leprosy or tuberculosis (Baker and Armelagos 1988; Rothschild & Rothschild 1996). Others believe syphilis originated in the New World and was brought to the Old World by Columbus’ crew in 1493; still others believe treponemal disease originated in Africa spreading with humans as they migrated throughout the world, mutating to form the syndromes: pinta, yaws, bejel and venereal syphilis (Ortner 2003). This study explores the possible presence of treponemal disease in Pre-Columbian North America. 54 individuals from the Archaic Period (4000-2900 BC) site of Carrier Mills in Saline County, Southern Illinois were examined for characteristic signs of treponemal disease, including 9 infants, 2 adolescents and 43 adults. Analysis suggests many individuals suffered from some syndrome closely matching the expected effects of a treponemal disease. Osteitis, periosteal reaction, lesions, joint fusion, and saber shins i were among the characteristics found in this population. Therefore, the Black Earth site of the Carrier Mills Archaeological District in southern Illinois provides strong evidence of treponemal disease in the New World prior to 1493 AD. ii ACKNOWLEDGMENTS First, I would like to express my deepest sincerities to God and to my family, my mother Helen, my father Larry, my brother Brad, and my grandmother Mary Jane for all that they have done for me.

INTRODUCTION “The ‘Great Pox’ spread rapidly, afflicting victims with suppurating sores that ate away flesh and bone and was followed by deformity, insanity and death” (Pook 2001:1). This was believed to be the “Wrath of God,” his punishment for decadence and immorality (Salt 2002). The “Wrath of God” is better known today as syphilis. Syphilis, or the “Great Pox,” as it was referred to in Medieval times, was for most people a terrifying disease with many consequences. The biggest question to revolve around the disease of syphilis is its place of origin: just where did this foul disease originate? In anthropology today, there is a long-standing debate concerning the origin of treponemal disease. This debate began near the end of the 19th century (Ortner 2003) and includes two major themes: 1) where did the first treponemal disease originate; and 2) is treponemal disease one syndrome or several different syndromes, known collectively as treponematoses? Some researchers argue that syphilis originated in the Old World but was not diagnosed as syphilis until the fifteenth century, due to its similarities to other diseases such as leprosy and tuberculosis (Holcomb 1934; Crosby 1969; Rothschild and Rothschild 1996; Bogdan and Weaver 1992). Other scholars argue that syphilis originated in the New World and was brought to the Old World by Christopher Columbus and his crew in 1493 AD, following their return from the New World (Baker and 2 Armelagos 1988; Cockburn 1963). Still other theories suggest that syphilis originated in Africa, spreading as humans migrated throughout the world and becoming the syndromes of treponemal disease we know today (Hudson 1965; Ortner 2003; Bogdan & Weaver 1992). In order to study disease in ancient populations, we must turn to the discipline of paleopathology. Paleopathology is the “study of disease, both human and nonhuman, in antiquity using a variety of different sources including human mummified and skeletal remains, ancient documents, illustrations from early books, painting and sculpture from the past, and analysis of coprolites” (Ortner 2003:8). In studying ancient human remains we can gain a glimpse of what ancient peoples’ lives might have been like. Paleopathology is particularly important in the study of archaeological human remains. In these ancient contexts, written records of health and medical practices are often missing (Lovell 2000). Paleopathology aims to rebuild the life of diseases historically and geographically, to shed light on cultural processes and their interaction with disease, to trace the evolution of diseases through time, and to gain a better understanding of disease processes and how they affect the growth and development of bone through the study of human archaeological remains (Ibid.). The most important step in paleopathological investigation is a clear description of the changes observed on the bones and the documentation of these changes (Lovell 2000). Part of documenting the changes involves recording any patterns of lesions found on the bone and also within the individual. If lesions are found on the bones, it is important to identify the specific bone, the section of bone involved, the aspect of the bone, and the distribution of the lesions on the bone (Ibid.). 3 When pathological lesions are found on the bones of an individual, we must ask ourselves 1) if the lesions occur on one side of the body or if they are bilateral when paired bones are present, 2) if there are similar lesions elsewhere on the skeleton of the individual, and 3) if there are different types of lesions on the skeleton (Lovell 2000). These types of questions are crucial in the differential diagnosis of skeletal lesions (Ibid.). Treponemal disease is but one of many different diseases that affect the human skeleton. Treponematosis, along with tuberculosis, leprosy, tumors, osteomyelitis, and Paget’s disease leave destructive lesions on the skeleton. The lesions of these diseases are so similar that differential diagnosis becomes difficult. Hence, the distribution of lesions within the skeleton of an individual and within the sample become very important factors. The purpose of this research is to contribute to the debate on the origin and development of treponemal disease. Was treponemal infection present in the New World prior to 1493 AD? Powell and Cook (2005:4) state that treponemal disease has been present in North America “at least fifteen centuries before the first voyage of Columbus.” According to Rothschild (2003; 2005), the oldest known skeletal population in North America to exhibit treponemal infection inhabited the Windover site in Florida, which dates to approximately 7900 B.P. Other sites where treponematoses have possibly been detected in North America include: Carrier Mills in Illinois (ca. 6300 B.P.); the Ward site in Kentucky (ca. 4300 B.P.); the Lu-25 site in Alabama (ca. 4300 B.P.); the Oconto County site in Wisconsin (ca. 3250 B.P.); Frontenac Island in New York (ca. 2000 B.P.), Libben in Ohio (1200-850 B.P.) and Amaknak in Alaska (Rothschild 2003; 2005). Was treponemal infection found in Illinois prior to 1493 AD and, if so, during what time 4 period did it originate? According to Baker and Armelagos (1988), treponemal disease has existed in Illinois for the past 3,000 years. Most of the sites discussed are from the Middle to Late Woodland (1000 BC – AD 1000) and Mississippian (AD 1000 – 1400) periods; two sites mentioned date to the Late Archaic (3000 – 1000 BC) period, the Klunk site (920 BC) (Powell et al. 2005) and the Morse site (1500 – 1000 BC) (Baker and Armelagos 1988). Is there more evidence supporting the presence of a treponemal infection from the Archaic period in Illinois? This research provides strong evidence that a treponemal disease did exist within the Archaic period sample of the Carrier Mills Archaeological District. Further analysis provides confirmation that a non-venereal form of treponemal disease, similar to yaws, was present in Illinois prior to 1493 AD. The importance of this research is to help elucidate the place of origin of treponemal disease so that the disease itself may be better understood. This study is just one component of this ongoing debate. The many components together will tell us where treponemal disease originated, so that we can learn how it spread and whether or not it is one or several different syndromes. Studies of disease in ancient populations provide insight into the geographical and chronological distribution of disease, responses to stress, the conditions of a society and its growth and how the society functioned as a whole (Armelagos 1969). Cultural differences, life patterns and life-span may also be inferred from the skeletons through examination of burial practices, burial goods, the determination of age and sex, and overall health of the individuals in the sample. This research and analysis will use a narrow focus on the paleopathological evidence found in the Carrier Mills Archaeological District to determine the presence or absence of treponemal disease and to also attempt to address some of these larger issues. 5 CHAPTER 2 THEORIES AND ETIOLOGIES OF DISEASES 2.1 Hypotheses of the Origin of Treponemal Disease There are two major hypotheses concerning the geographic origin of syphilis. The first one is the Columbian Hypothesis, based on statements from Columbus’ contemporaries Ulrich von Hutten and Ruy Diaz de Isla that Christopher Columbus and his crew brought syphilis back to Europe upon their return in 1493 from the New World, where syphilis supposedly originated (Crosby, Jr 1972; see also: Baker and Armelagos 1988; Bogdan and Weaver 1992; Cook 1993; Rodríguez-Martín 2000). This theory gained its’ popularity in the sixteenth century and is still used today. Crosby (1969) states that the “pox” was brought back from the New World to the Old World by Columbus and his crew in the 1490’s. The evidence he gives is the historical accounts of the physicians and the historians at the time of the epidemic. The reports that exist were written after the epidemics, but Crosby (1969) suggests that the reason for this is that the more prominent people of the times wanted to suppress any and all negative reports about the New World. Therefore, with the absence of written reports, perhaps lost or buried in archives until after the epidemics, and with the agreement of the disease being new to Europe, treponemal disease must have originated in the Americas. 6 The second hypothesis is the Pre-Columbian Hypothesis, which suggests that syphilis existed in the Old World long before Christopher Columbus’ historic journey to the New World. Since leprosy already existed in the Old World, researchers from the 1400’s and 1500’s (Francisco Villalobos, John Maynard, Petrus Andraes Matthiolous, Ruiz Diaz de Isla) believed that syphilis may have been misdiagnosed as leprosy (Holcomb 1934). In other words, doctors in Medieval times thought the two diseases were one based upon their similar symptoms and did not realize that a separate disease even existed other than leprosy (Baker and Armelagos 1988; Bogdan and Weaver 1992; Rodríguez-Martín 2000). Cockburn (1963:154) states that the original peoples of the “New World were already infected when they first crossed the Bering land bridge tens of thousands of years ago.” Humans carried many different parasites with them when they began migrating to other lands, including some form of treponeme. This means that treponemal disease was everywhere that humans inhabited before the time of ocean travel (Cockburn 1963), hence before Christopher Columbus sailed the ocean blue. 2.2 Hypotheses on the Development of Treponemal Disease In addition to the two major hypotheses regarding the geographic origin of syphilis, there are three major hypotheses involving the development of the syndromes. These hypotheses are referred to as the Unitarian Hypothesis, the Non-Unitarian Hypothesis, and Livingston’s Alternative Hypothesis. The Unitarian Hypothesis suggests only a single treponematosis was present in both the Old and New Worlds before Columbus’ journey. This theory, proposed by Hudson (1965), suggests that since there 7 were no specific differences between the bacteria of the four syndromes, the syndromes should all be classified as strains of one disease known as treponematosis. This treponemal disease is extremely flexible and evolved with various human populations, forming the different syndromes that are known today. Hudson (1965) also proposes that yaws was the first treponematosis and that it probably originated in sub-Saharan Africa, accompanying humans as they extended their range through migrations to other lands. As humans migrated, the climate changed, causing yaws to evolve into endemic treponematosis (Ibid.). Humans became more sedentary and villages emerged. Endemic treponematosis flourished through children because the barriers of clothing and personal hygiene had not come into effect yet (Ibid.). Other changes occurred as urban life emerged, discouraging the spread of endemic treponematosis and encouraging venereal treponematosis. The sexually transmitted bacteria became more successful within sedentary villages due to natural selection. The mode of transmission remained the same, direct contact of an open sore but because humans changed their behaviors, the bacteria found new ways to invade the host. Treponemal disease then would be a biological gradient based on each person’s physical and cultural states, presenting itself as different clinical patterns according to climate and human behaviors such as better hygiene, wearing more clothing and improved living conditions (Ibid.). The Non-Unitarian Hypothesis suggests that there are four treponematoses; pinta, yaws, endemic syphilis, and venereal syphilis, resulting from the mutations of the first treponemal bacteria (Aufderheide and Rodríguez-Martín 1998; Rodríguez-Martín 2000). Hackett (1967) proposes that before 20,000 B.C., the first treponemal disease would have been pinta, which arose from an animal infection. A genetic mutation, which took place 8 about 10,000 B.C., resulted in yaws, a much more invasive disease with tissue destruction. The next mutation occurred about 7,000 B.C., also the time when a climatic change occurred in Africa, Asia and Australia, which resulted in endemic syphilis, in these dry, warmer regions of the world. A third mutation occurred around 3,000 B.C., that resulted in a mild form of venereal syphilis. The last mutation occurred in late fifteenth century in Europe, with a much more serious form of venereal syphilis occurring as the result (Ibid.). As humans began to cluster in villages and wear more clothing, the treponemal bacterium had to adapt to its human host in order to survive. The changing environmental conditions along with the mutations in the bacteria meant that bacteria that were transmitted through sexual contact were the favored bacteria. The bacteria that were transmitted through skin-to-skin contact were the bacteria that died out. The last hypothesis is Livingston’s Alternative Hypothesis. Livingstone (1991) believes that there is not enough evidence to assume that the treponemal diseases have adapted in humans throughout human evolution because it is a newer disease, which has mutated into several different syndromes of treponemal infection, but was introduced to the New World at the time of Columbus (Ibid.). He suggests that the increase in rates of the treponemal disease in cases in the Americas is due to an introduction of an extremely toxic form of treponemal infection from the Old World as a result of increased contact with Africa (Livingstone 1991; Rodríguez-Martín 2000). This would have been a new strain of treponemal infection to the Europeans, which would have resulted in a low immunity to the disease, causing it to spread rapidly through the sexual practices in Europe at this time, thus increasing the virulence or infectiousness of the disease (Aufderheide and Rodríguez-Martín 1998; Rodríguez-Martín 2000). 9 Of these hypotheses of origin and development, it is likely that the disease developed due to a variety of factors. Treponemal disease likely originated with humans, spreading as humans migrated to new lands. Therefore, treponemal disease would have existed in both the Old and New Worlds before Columbus’ journey. It is likely that the syndromes of treponematoses are all different syndromes that have existed independently in different parts of the world at different times and, in other times coexisting in the same parts of the world. Now that we have some idea of the hypotheses concerning the origin and development of treponemal disease, the four syndromes of treponemal disease are described in detail in the following section. 2.3 Syndromes of Treponemal Disease They were byles, sharpe, and standynge out, hauynge the simylitude and quantite of acornes, from which came so foule humours, and so great stinche, that who so ever ones smelled it, thoughte hym selfe to be enfecte. The colour of these pusshes [pustules] was derke grene, and the syghte therof was more grevouse unto the patiente than the peyne it selfe: and yet their peynes were as thoughe they had lyen in the fyre (Ulrich von Hutten 1540:2). This was the first recorded description of syphilis from the 1500’s. Today’s description is much more scientific, but not significantly different in detail. The first symptom of syphilis is a painless ulcer or chancre (Lukens 2005). After the chancre 10 develops, various skin eruptions follow which contain mucous patches that ooze yellowish-greenish pus. Treponemal disease is a chronic infectious disease caused by the bacterium Treponema pallidum. These bacteria are known as spirochetes. The disease caused by Treponema pallidum can be broken down into four different syndromes, with a fifth syndrome being transmitted congenitally. The syndromes are: Pinta, Yaws, Endemic Syphilis, Venereal Syphilis and Congenital Syphilis. The differences among the syndromes mostly depend upon the geographic region in which the infected individual lives (Larsen 1997; Aufderheide and Rodríguez-Martín 1998; Ortner 2003). Listed below are the syndromes of syphilis with a brief description of each one, except for Pinta (Treponema pallidum careteum) which affects only the skin and will not be discussed here because it cannot be found in the archaeological record. Appendix A is a key of differential diagnosis between yaws, endemic syphilis, venereal syphilis, congenital syphilis, tuberculosis, leprosy, tumors, osteomyelitis and Paget’s disease. 2.3.1 Yaws Yaws (Treponema pallidum pertenue) is a chronic, recurrent, infectious, nonvenereal form of the treponematoses that is usually acquired in childhood through direct contact of an open sore or indirect contact by flies or other insects. Therefore, yaws is most often seen in children and adolescents (Ortner 2003; Aufderheide and RodríguezMartín 1998). Transmission may also occur congenitally (Ortner 2003). Congenital yaws results when a woman acquires yaws later in life, transmitting the bacteria to the fetus via the bloodstream. This does not mean that a young pregnant woman acquiring 11 yaws cannot pass the pathogen to the fetus, but that if an older pregnant woman acquires yaws, she is more likely to pass the pathogen to her fetus, since yaws is typically acquired in childhood. Only the skin and bones are affected by this treponemal disease. Yaws can occur in three different stages. The first stage is characterized by the “mother yaw,” or the first lesion. This mother yaw appears at the initial site of infection, usually the legs, between five to eight weeks after the initial exposure (Powell and Cook 2005). The mother yaw will become larger or thicker, circular, and begin to itch resulting in a tumor that will eventually form a lesion. This stage can last for six months and it ends with the mother yaw healing spontaneously (Powell and Cook 2005; Aufderheide and RodríguezMartín 1998). After a period of latency, the second stage begins with similar lesions to the mother yaw. The lesions from this second stage form a general pattern all over the body (Powell and Cook 2005). These lesions are small and either de-pigmented or hyperpigmented. If this stage is not treated, it can last up to five years, alternating between remissions and relapses (Ibid.). Bone lesions may occur at this stage in the shafts of long bones, the paranasal maxillae, or the hand phalanges. Plantar lesions may also develop in the feet causing severe debilitation and resulting in individuals walking on the edges of their feet (Ibid.). The final or tertiary stage is the most destructive stage of yaws, occurring after a period of latency that can last for several years. This is the stage that has the most extensive skeletal lesions. Although very destructive to skin, mucous tissues and bone, the central nervous system, cardiovascular system and internal organs are not affected, which is seen in venereal syphilis (Powell and Cook 2005). The most common bone 12 affected is the tibia, followed by the fibula, clavicle, femur, ulna, radius and bones of the hands and feet (Aufderheide and Rodríguez-Martín 1998). The most typical or characteristic feature of this stage is the saber shin, also known as “boomerang leg” (Roberts and Manchester 1995; Ortner 2003). Saber shin is a remodeling of the anterior crest of the tibia, followed by bone deposition. Rarely the posterior aspect of the tibia’s shaft is changed. This remodeling of bone results in a curved appearance similar to that of a cavalry saber blade, hence the name saber shin (Powell and Cook 2005). Another feature that characterizes yaws is dactylitis (Aufderheide and RodríguezMartín 1998; Douglas et al.1997). Dactylitis is a bone change occurring in the hands that leads to enlargement of the phalanges. These bony changes in the hands are more common in young individuals and are uncommon in venereal syphilis (Aufderheide and Rodríguez-Martín 1998). Skull lesions are uncommon in yaws, but when they do occur, they are less severe than cases with venereal syphilis. The frontal or parietals may have shallow, pitted cortical lesions but the most destructive lesions are more likely to occur in the nasal-pharyngeal region of the cranium (Powell and Cook 2005). Seven to 8% of cases with skeletal involvement have extensive destruction of the nasal area and of the maxilla (Aufderheide and Rodríguez-Martín 1998). This results in the condition known as gangosa (Roberts and Manchester 1995). Gangosa is the destructive ulceration of the nasal-palatal region of the face. In 5% of cases with gangosa, perforation of the hard palate occurs, and it is more severe than in cases found with venereal syphilis (Aufderheide and Rodríguez-Martín 1998). Nasal-palatal destruction and tibial involvement are frequently found in yaws. 13 Differential diagnosis between yaws and venereal syphilis can be very complicated. For this reason, geographic factors play an important role in the diagnosis of yaws (Aufderheide and Rodríguez-Martín 1998). Yaws is generally found in rural areas of western and equatorial Africa, Latin America, the Caribbean Islands, Southeast Asia, North Australia, New Guinea, and the islands of the Southern Pacific Ocean (Aufderheide and Rodríguez-Martín 1998; Roberts and Manchester 1995). Rothschild (2003) speculates that yaws may be the treponemal infection that was present in North America before Columbus’ journey. 2.3.2 Endemic syphilis Endemic syphilis (Treponema pallidum endemicum) is an acute, infectious disease that occurs primarily in children between the ages of two and ten years within rural areas. Transmission of endemic syphilis occurs directly and indirectly through contact of the infectious lesions of the skin and mucous membranes or through contaminated linens. The infection may be spread by the shared use of eating and drinking implements, such as pipes, toothpicks, or cigarettes (Aufderheide and Rodríguez-Martín 1998; Powell and Cook 2005). The initial lesion is small, painless, and often unobserved resulting in a cutaneous and mucosal rash with inflammatory destructive lesions on the skin, bones and the naso-pharyngeal region (Powell and Cook 2005; Aufderheide and Rodríguez-Martín 1998). A latent period can occur for months or even years, followed by infectious lesions that have a hard irregular center consisting of dead cells and pus. These lesions affect the skin, nasopharynx and bones (Powell and 14 Cook 2005). Spontaneous healing of the lesions may occur, but the damage they cause can be debilitating. The skeletal lesions that occur in endemic syphilis are almost identical to those occurring in yaws (Aufderheide and Rodríguez-Martín 1998). These skeletal lesions are also morphologically indistinguishable from the skeletal lesions of venereal syphilis (description provided below). The differences between yaws and endemic syphilis can be seen when looking at the population as a whole. In an epidemiological approach, Rothschild et al. (2000) describe endemic syphilis as having a high population frequency, occurring in both subadults and adults, affecting few bone groups and very little if any involvement of the hands and feet, unlike yaws. With endemic syphilis, as with the other treponematoses, the tibia is the most frequently affected bone, with the typical features being the deformity of the saber shin (Aufderheide and Rodríguez-Martín 1998; Roberts and Manchester 1995). Some of the other more commonly involved bones include the fibula, ulna, radius, clavicle, phalanges and calcaneus (Aufderheide and RodríguezMartín 1998). Nasal-palatal destruction and tibial involvement are frequently found in this syndrome. Transmission does not occur congenitally, thus endemic syphilis does not leave any traces on the teeth such as the commonly found Hutchinson’s incisors or mulberry molars that are found in congenital syphilis, which are discussed below (Ibid.). Endemic syphilis has a low mortality rate and acts as an endemic disease, limited to regions of low socioeconomic levels and bad hygiene (Aufderheide and RodríguezMartín 1998). This syndrome is often found in arid and warm climates of the eastern Mediterranean Sea, southwestern Asia, and sub-Saharan Africa (Ibid.). Rothschild 15 (2003) speculates that not only yaws but also endemic syphilis was present in North America before Columbus’ journey. 2.3.3 Venereal Syphilis Venereal syphilis (Treponema pallidum pallidum) is an acute, sub-acute, or chronic infectious disease that has three different phases and is the most dangerous of the syndromes (Aufderheide and Rodríguez-Martín 1998; Powell and Cook 2005). Transmission occurs directly through sexual contact. Indirect transmission can occur through infected objects such as needles or nonsexual contact of an open sore (Aufderheide and Rodríguez-Martín 1998). Venereal syphilis is characterized in its primary stage by a lesion or chancre at the point of entry (Ortner 2003). A period of incubation occurs for approximately three weeks. After this period a small, painless chancre appears on the genitals (Powell and Cook 2005). If the chancre is not treated, the bacteria will rapidly multiply, spreading throughout the body via the bloodstream (Ortner 2003). This leads to the secondary stage which includes a variety of lesions appearing on the skin and genitals (Powell and Cook 2005). In the secondary stage a rash develops, which affects the skin and mucous membranes (Aufderheide and Rodríguez-Martín 1998). The lesions in this stage are highly infectious. The bones of the distal limbs are often involved, resulting in periostitis and osteitis. The various lesions in this phase usually occur in the first year, but they can last up to four years (Powell and Cook 2005). 16 After a period of latency, the tertiary stage develops. In this third stage the lesions that occur affect the skin, skeletal, cardiovascular, and central nervous systems in 20 - 50% of cases, if left untreated (Aufderheide and Rodríguez-Martín 1998). This is why venereal syphilis is the most dangerous syndrome. Seventy percent of all the skeletal lesions occur on the tibia, cranial vault, and bones of the nasal cavity (Ortner 2003). This syndrome has been nicknamed the “Great Imitator” because the symptoms of this disease are so variable and many resemble those of other diseases, such as leprosy, tuberculosis, tumors, osteomyelitis, and Paget’s disease (Aufderheide and RodríguezMartín 1998). Aufderheide and Rodríguez-Martín (1998) state the most characteristic skeletal lesions of venereal syphilis are those of the skull, specifically the parietal and the frontal bones. This characteristic is known as Caries sicca and is manifested as sunken, destructive areas of bone loss and bone growth forming an irregular surface on the cranial vault. In other words, the cranial vault contains a series of hills and valleys instead of being smooth. Other commonly affected bones include the tibia, nasal-palatal region, sternum, clavicle, vertebrae, femur, fibula, humerus, ulna and radius (Ibid.). Of the previous bones named, the tibia exhibits syphilitic lesions ten times more often than the others (Bogdan and Weaver 1992). Ortner (2003) states the spine is rarely involved, but when it is involved, the cervical vertebrae are most often affected. Nasal-palatal destruction can be found in a less severe form than seen in yaws, and the most commonly affected joint is the knee (Aufderheide and Rodríguez-Martín 1998; Roberts and Manchester 1995). 17 2.3.4 Congenital Syphilis Venereal syphilis can also be transmitted from the mother to the fetus, which results in congenital syphilis. This may occur in two ways. First, congenital syphilis may be transmitted from a mother with venereal syphilis, through the placenta to the fetus, infecting the fetus with spirochetes (bacteria). The infected fetus will either be aborted or die soon after birth (Aufderheide and Rodríguez-Martín 1998). The spirochetes cause a degeneration of the cells that develop into bone. This results in a 50 % fatality rate of affected fetuses, but in the case of a mild infection, infants may live for many years with a dormant phase of congenital syphilis (Ibid.). The second way that transmission may occur is during birth as the infant passes through the birth canal of an infected mother (Powell and Cook 2005). Congenital syphilis can be divided into two different phases, an early phase and a late phase. The early phase occurs in infants from birth to four years (Powell and Cook 2005). The most characteristic symptom in newborns is rhinitis, which is an inflammation of the mucous membranes in the nose (Lukens 2005). This inflammation causes the formation of the permanent central incisors and first molars to be disrupted, resulting in the dental stigmata of congenital syphilis described below. A rash develops on the surfaces of the hands, feet, anus and mouth (Powell and Cook 2005). The skeletal system becomes involved, leading to osteochondritis (i.e. inflammation of the bone and cartilage), perichondritis (i.e., an inflammation of the connective tissue membrane that surrounds the cartilage) and periostitis (i.e., an inflammation of the membrane of connective tissue that covers all bones). The shafts of the tibiae are the most commonly involved long bones, but any bone can be involved. Infants who survive this stage will 18 have lesions that heal spontaneously, so much so that there are no traces of the lesions later in life (Ibid.). According to Aufderheide and Rodríguez-Martín (1998), osteochondritis of the metaphysis is found in the majority of the archaeological specimens. Periostitis of the tibia and the femur can also be found (Ortner 2003). The most frequently involved bones are the tibia, radius, ulna and the cranium (Aufderheide and Rodríguez-Martín 1998). The late phase of congenital syphilis occurs in children and adolescents from five to fifteen years of age (Powell and Cook 2005). This is the phase where disfiguration of the cranium occurs. Saddle nose may occur which results in the bridge of the nose collapsing. Other alterations of the skull include Parrot’s sign (prominent frontal bosses), a high palatal arch, and a disproportionate size of the maxillae and mandible (Ibid.). Postcranial alterations of the skeleton include flaring scapulae, thickening of the sternum and clavicles, swelling of the knees, and saber shins. The alterations to the skeleton discussed here remain with the individual throughout life (Ibid.). According to Cook (1993) and Aufderheide and Rodríguez-Martín (1998), characteristics to look for in the teeth of an individual with congenital syphilis are Hutchinson’s incisors, mulberry molars and Moon’s molars, which may also be associated with saddle nose. Hutchinson’s incisors are permanent central incisors that are smaller than normal and exhibit a shallow notch in the middle of the incisal edge, a screwdriver shape, the presence of a diastema between the incisors, a dirty grey surface, with the crown surfaces tapering mesially and distally (Shafer et al. 1974; Hillson 1996; Pindborg 1970; Hillson et al. 1998). Moon’s molars or bud molars are permanent first molars exhibiting a clinched appearance of the crown, a narrow occlusal area giving the 19 tooth a domed or bud-like appearance, and bulbous crown formation (Colby et al.1971; Hillson 1996; Hillson et al.1998). Fournier’s or mulberry molars are permanent first molars with the occlusal surface altered so that it looks like a mulberry and the tooth is also smaller than the normal first and second molars (Hillson 1996; Pindborg 1970). The permanent canines, both upper and lower, may also be affected, but these changes are not as noticeable as with the permanent incisors and molars. A hypoplastic defect occurs on the canines in the form of a circular groove around the tip of the tooth (Hillson et al. 1998; Jacobi et al. 1992). This circular groove may become a shallow notch due to attrition. The canine may also be yellowish in color and may have a puckered appearance (Jacobi et al. 1992). 2.4 Other Studies of Treponematoses Brothwell (1970) suggested an evolutionary tree for the treponemes which included extinct forms of the disease. The evolutionary tree began at the base with a nonhuman treponeme branching into two forms, one branch for extinct forms and one branch for pinta. The tree trunk then continues branching to form yaws, then possibly another branch for more extinct forms, with the trunk continuing until it branches off with endemic syphilis and then finally branching into venereal syphilis. This tree would represent various forms of the treponemes advancing to more complicated forms which would not be ancestral to the varieties of treponemes that occur today (Brothwell 1970). My point here is that another form of treponematosis could have been present in North America besides the syndromes of yaws, endemic syphilis, and venereal syphilis we 20 know today. This other form could have existed for thousands of years and then due to forces of natural selection, it could have become selected against and died, thus becoming extinct. In 1995 Rothschild, Hershkovitz, and Rothschild proclaimed the earliest evidence of treponemal disease came from Homo erectus. They reanalyzed periosteal reaction patterns of several H. erectus skeletal remains housed at the National Museum of Kenya in Nairobi. They found involvement of the long bones and upper and lower extremities. The periosteal reaction distribution pattern most closely resembled that of yaws. Their study would confirm an African origin for treponemal disease dating to the Middle Pleistocene (Rothschild et al. 1995). Another study conducted by Rothschild and Rothschild (1996) resulted in conclusions about the effects of venereal syphilis, yaws and endemic syphilis on populations. Venereal syphilis had a low population frequency (5-14%), a median number of bone groups were affected (2), and saber shins occurred without remodeling, or no periosteal reaction was evident on the surface of bones. Bone involvement in children was also rare (Ibid.). For cases with yaws, there was a high population frequency (21-33%), a median number of bone groups were affected (4), the hands and feet were affected, bone lesions occurred in subadults, and saber shins exhibited periosteal reaction (Ibid.). Endemic syphilis occurred with a high population frequency (25-40%), a median number of bone groups were affected (2), saber shins showed evidence of periosteal reaction, and the hands and feet were rarely affected (Ibid.). Rothschild et al. (2000) state that tibial changes are found in 99% of individuals with treponemal disease and therefore the tibia is critical to diagnosis of treponemal 21 infection. Treponemal disease can be recognized on the basis of periosteal reaction along with osteitis (Ibid.). Other diagnostic criteria include saber shin, the frequency of hand and foot involvement, and the number of bone groups affected (Ibid.). “Bone group” is an artificial construct used by Rothschild et al. (2000): “to quantitate the extent of skeletal involvement. Involvement of a skeletal component is treated as 1 bone group, whether that involvement is unilateral or bilateral. Carpal, tarsal, metacarpal, metatarsal, and phalangeal involvement are each considered single bone groups, whether ≥ 1 are affected.” (pg. 937). For example, the tibiae would be considered a bone group, as would the radii. Each group of bones in the hands and feet are considered a bone group. If one distal phalanx on the right hand is affected, then the hand phalanges are considered to be affected, no matter if it is the right or left side. In the study conducted by Rothschild et al. (2000), venereal syphilis was identified as affecting few bone groups (1.9), having a low population frequency (14% or less), unilateral tibial involvement and saber shin associated with periosteal remodeling. Yaws affected a median number of bone groups (4), had a high population frequency (more than 20%), affected the hands and feet frequently and produced bone lesions in subadults. Endemic syphilis affected few bone groups (2), exhibited a high population frequency (more than 20%), and occurred in subadults as well as adults (Ibid.). Rothschild et al. (2000) also found that in cases of yaws and endemic syphilis (bejel), 22 subadults and adults were affected at the same frequencies, while in populations with syphilis, subadults were affected with a 5% or less frequency. The study conducted by Rothschild et al (2004) found some of the same results as the study by Rothschild (2005). Both studies found that bone involvement occurred in 2– 13% of individuals with venereal syphilis, while individuals with yaws or endemic syphilis had bone involvement of 20–40%. Rothschild (2005) states the most critical skeletal criterion in diagnosing a treponemal disease is the pattern of periosteal reaction, tibial remodeling and bone destruction. This study also found that in cases of syphilis less than 5% of children have skeletal involvement. Children with yaws or endemic syphilis exhibited a rate of 10–20% skeletal involvement (Ibid.). Venereal syphilis rarely affected the hands and feet and the incisors and first molars were only affected in cases with venereal syphilis. Finally, the saber shin remodeling that occurs in venereal syphilis hinders the signs of periosteal reaction, making it difficult to see the actual reaction (Ibid.). In a study by Hutchinson and Richman (2006), skeletal samples were examined from the prehistoric southeastern United States to try to aid in the debate on the origin and geographic distribution of syphilis. The skeletal samples encompass a broad geographic and topographic range, including such time periods as the Archaic (8000 – 1000 BC) through the protohistoric (AD 1500 – 1600) periods. Their study assesses the presence of treponemal disease, venereal and nonvenereal, in an evolutionary context according to geographic, physiographic, and temporal patterns of treponemal disease. Hutchinson and Richman (2006) suggest that increases in the frequency of positive cases are due to an increase in population density and changing human behaviors. In other 23 words, the evolution of treponemal disease was caused by the changing environment and living conditions of the human host, instead of changes occurring within the pathogen itself. The bacteria, therefore did not change; genetically treponemal disease is one species that has adapted to the changing environment of the human host. Smith (2006) conducted a study on skeletal remains in the Western Tennessee River Valley consisting of eight sites spanning the Middle (6000-3000 BCE) to Late (2500-ca. 1000 to 500 BCE) Archaic and Early Woodland (500 BCE-0 CE) periods. Her study focused on sedentism and the advent of pottery, which she predicts can be correlated to the appearance of diseases like treponemal disease (Ibid.). The evidence of pottery at a site means that the community was using the site for long periods of time. This would mean that villages were beginning to emerge. The emergence of villages and a larger group of people living closer together would allow the spread of such diseases as the treponematoses. Smith (2006) found that out of 581 individuals, 13 (9 adults and 4 sub-adults) exhibited “periostitis pathognomonic or indicative of treponemal disease” (Smith 2006:207). The syndrome believed to have affected these samples is of a non-venereal form. This evidence is pre-Columbian with an increase in frequency occurring after 1000 CE. The increase in frequency was attributed to the advent of sedentism and agriculture (Ibid.). Levréro et al. (2007) conducted a recent study on a population of gorillas from the Republic of Congo who exhibited skin lesions indicative of yaws. In this study 17% of the 377 gorillas exhibited some type of lesion (Ibid.). The locations of the lesions were mainly on the faces of the gorillas. They found that in some instances the lesions were so 24 deep that they produced debilitating handicaps (Ibid.). It is interesting that yaws affects gorillas in some of the same ways as it affects humans. Levréro et al. (2007) found that yaws affected young gorillas, males were affected more than females, unmated adult males suffered more with lesions, and in non-breeding groups the immature gorillas suffered more from yaws. With the presence of yaws among non-human primates, this study and others like it can help us to determine what life might have been like for our hominid ancestors who suffered from nonvenereal treponemal disease. 2.5 Other Similar Diseases Treponemal disease produces effects on the bones of an individual that are very similar to other diseases. In the past others believed that perhaps syphilis was not recognized as a disease because it was so similar to tuberculosis or leprosy. Hackett (1967) states that leprosy was used as a blanket term to refer to several different diseases present in Europe in Medieval times. The Bible and medieval documents are used to demonstrate the confusion between syphilis and leprosy (Baker and Armelagos 1988). Here, I will describe the diseases of tuberculosis and leprosy, in order to aid in the process of differential diagnosis between treponematoses, tuberculosis, and leprosy. Other diseases that affect the skeleton in similar ways to treponemal disease include tumors, osteomyelitis and Paget’s disease. These other diseases will also be discussed in the section below. 2.5.1 Tuberculosis 25 Tuberculosis is an acute and chronic infectious disease caused by the bacterium Mycobacterium tuberculosis or M. bovis. M. tuberculosis is the most common bacterium that affects humans. M. bovis can also affect humans, but it is most commonly found in cattle (Ortner 2003). M. tuberculosis is transmitted from human to human through the air by inhaling bacteria within moisture droplets that have been spread into the air from the cough of an infected person (Aufderheide and Rodríguez-Martín 1998). The disease usually begins in the lungs as a respiratory infection. The bacteria then multiply in the lungs, spreading to surrounding tissues (Ibid.). The tissues may die, resulting in an area of scar tissue that may contain live M. tuberculosis bacteria that can remain dormant for some time. These dormant bacteria can reactivate the disease if other stressors affect the lung, such as invasion of the lung by cancer or from the person contracting HIV/AIDS (Powell 1992; Aufderheide and Rodríguez-Martín 1998). This process is known as the primary infection (Aufderheide and Rodríguez-Martín 1998). The primary infection can lead to a secondary infection by the dissemination of the bacteria via the blood stream to any or all of the organs in the body. Thus, the infection reaches the skeletal system via the bloodstream (Ortner 2003). The most important factor to remember in the destruction of the skeletal tissue is the “pattern of resorptive lesions with little evidence of proliferative, reactive changes” (Aufderheide and Rodríguez-Martín 1998:134). In other words, tuberculosis causes a resorption of bone with very little bone growth or evidence of a reaction occurring. Skeletal tuberculosis is most often found in areas of trabecular bone (Aufderheide and Rodríguez-Martín 1998). For this reason, the spine is involved in more than 40% of the skeletal lesions. The most common area of involvement in the vertebrae is the 26 anterior surface of the thoracic or lumbar vertebral body, which occurs in approximately 80% of cases (Ibid.). Erosion occurs producing an abscess that extends into the intervertebral space. Herniation of the intervertebral disk occurs, causing the spread of the abscess through the cartilaginous defect and into the vertebral body. This produces a “narrowing of the affected intervertebral disk space” (Aufderheide and Rodríguez-Martín 1998:122). The abscess then progresses in a vertical fashion to an adjacent vertebral body, where the process occurs again. Posterior involvement of the vertebral body only occurs in approximately 20% of the cases of skeletal tuberculosis, with the same type of process occurring as in anterior vertebral body involvement. Occasionally the vertebral neural arch, processes or articular elements are directly involved (Ibid.). A progressive destruction of the vertebral body often leads to the collapse of the vertebral body. This collapse causes shortening of the trunk of the individual and anterior bending of the spine above the collapsed area, which is known as kyphosis. In kyphosis, usually two or three thoracic vertebrae are involved, but it may involve as many as six or more vertebrae (Ibid.). Only 10% of cases result in paraplegia, due to the compression of the spinal cord and nerves (Ibid.). Other sites of tuberculosis in the skeletal system involve the joints. Bacilli are disseminated to the trabecular bone of long bones, which resides in the metaphysis. Most often the hip and knee are involved (Aufderheide and Rodríguez-Martín 1998). Involvement of the hip occurs in 20% of cases, this being the second most frequent site of skeletal lesions (Ibid.). It is most common in children between the ages of three and ten (Ibid.). Most frequently bone destruction occurs in the acetabulum, but the femoral head, neck and trochanter may be affected. Dislocation of the hip may occur if there is 27 extensive destruction of the area through exposure of the bone by ulceration of the cartilage (Ibid.). Exposure of the bone will result in bone-on-bone contact causing eburnation. Eburnation may cause the femur neck to crumble, thus dislocating the hip (Ibid.). Only 16% of cases of skeletal tuberculosis involve the knee, resulting in deforming lesions on the surface of the knee, and upper extremity joints are involved much less frequently (Ibid.). The ribs, flat pelvic bones, sternum, and sometimes the cranium in adults are involved (Aufderheide and Rodríguez-Martín 1998). Rib lesions occur in 9% of individuals with pulmonary tuberculosis (Ibid.). The internal surfaces of the ribs are affected by a mild to moderate periostitis. This usually involves several adjacent ribs with ribs four to eight being the most common ones involved. Sometimes the central portion of the rib body is involved, but rarely are the costal head and neck affected. Rib lesions are more common on the left side of the thorax (Ibid.). The cranium is rarely involved in tuberculosis, but when it does occur, it affects young adults almost exclusively. The most common area of involvement is the cranial vault. Here, tuberculosis appears as “small numerous areas of destruction, less than 2 cm in diameter, with poorly defined margins and some surrounding reactive sclerosis” (Aufderheide and Rodríguez-Martín 1998:140). The lesions often cross the sutures of the cranium, and the destruction starts on the outside and moves to the inside of the skull. The facial bones, mandible and cranial base may be involved, but it is rare (Ibid.). Since tubercular skeletal lesions that occur in areas other than spine are almost indistinguishable from other diseases, it is important to study the lesions and their distribution not only within the skeleton, but also within the population being examined. 28 Only about 1% of all patients with tuberculosis have exhibited skeletal lesions (Aufderheide and Rodríguez-Martín 1998). The main difference between tuberculosis and treponemal disease is that tuberculosis destroys already existing bone tissue, while in treponemal disease there is a proliferation of new bone (Powell 1992). Tuberculosis does not produce new bone, it only destroys bone. 2.5.2 Leprosy True leprosy was not known until after 300 BC (Baker and Armelagos 1988). In Medieval times leprosy was the term used for disfiguring, depigmenting diseases often spread by sexual contact, heredity, and breastfeeding. The transmission of leprosy in Medieval times was thought to be from sexual intercourse (Ibid.). Since leprosy is not transmitted sexually, nor is it hereditary, this gives reason to believe that venereal syphilis was confused as leprosy (Ibid.). On the other hand, Crane-Kramer (2002) disagrees that there was any confusion between leprosy and syphilis and provides an analysis of skeletal material (600 individuals) that suggests a diagnostic confusion between leprosy and syphilis did not exist in Medieval times. Leprosy, or Hansen’s disease, as it is sometimes referred to, is a chronic infectious disease caused by the bacterium Mycobacterium leprae. In humans it affects the skin, nasal tissues, peripheral nerves, and the skeleton (Aufderheide and RodríguezMartín 1998). Leprosy has a worldwide distribution, but it is more commonly found in tropical and subtropical areas of Asia, Africa, and the Americas (Ortner 2003). This disease is found more commonly in rural areas as opposed to urban ones (Aufderheide and Rodríguez-Martín 1998). Transmission occurs by the inhalation of the M. leprae 29 bacteria through moisture droplets in the air. Direct skin-to-skin contact may also transmit the bacterium from person-to-person through an ulcerated, infected lesion (Ibid.). The ratio of infected males to females is 2:1 (Ortner 2003). Bones are only directly involved in approximately 5% of all patients with leprosy (Ibid.). In leprosy, more commonly there is a resorption of bone, whereas bone lesions are less frequent. This resorption occurs in the nasal spine (Buckley and Tayles 2003). Leprosy has two main clinical forms: lepromatous leprosy (LL) and tuberculoid leprosy (TT) (Aufderheide and Rodríguez-Martín 1998). Both of these forms of leprosy are discussed below. 2.5.2.1 Lepromatous Leprosy (LL). This form of leprosy creates alterations to the anterior face (Steyn and Henneberg 1995). It begins as a chronic “inflammation of the nasal mucous membrane” (Lukens 2005:1278), known as rhinitis. The nasal membrane forms lesions, becomes encrusted, and may bleed, which produces a perforation of the inner wall of the nose (Aufderheide and Rodríguez-Martín 1998). This infection may spread to the superior surface of the hard palate, to the nasal bone, nasal spine and the central maxilla. Erosion of these areas can lead to collapse of the bridge of the nose, resulting in the feature known as saddle nose, which is unique to lepromatous leprosy (Ibid.). If the lepromatous rhinitis spreads to the maxilla, it will erode the maxillary bone beginning in the midline and extending to the palate (Aufderheide and Rodríguez-Martín 1998). This results in the loss of the upper central incisors and may even extend to the canines. The mandible is not affected. All of the facial changes discussed above are together known as facies leprosa, which can be seen in archaeological specimens (Ibid.). 30 Postcranially the long bones of the extremities are sometimes affected, beginning with the metaphysis and possibly spreading to the epiphysis or medullary canal (Aufderheide and Rodríguez-Martín 1998). Involvement occurs more commonly in the hands and feet. In the hands, the most common area of involvement is the phalanges. Complete destruction of the distal phalanges may occur, which results in shortening of the fingers (Ibid.). In the feet, the metatarsals are the most commonly affected bones, as well as the talus and the calcaneus. This may result in club-shaped stumps for the feet (Ibid.). The bones of the hands and feet are very badly disfigured through the destruction that occurs from leprosy (Manchester and Roberts 1989). 2.5.2.2 Tuberculoid Leprosy (TT). In tuberculoid leprosy the number of bacteria in the skin lesions are greatly reduced, which means that this form of leprosy is much less infectious (Aufderheide and Rodríguez-Martín 1998). The characteristic changes of facies leprosa present in lepromatous leprosy are absent in tuberculoid leprosy (Ibid.). Skin lesions are fewer in number, usually a single lesion occurs, but the lesions that do occur extend to much deeper levels. Similar effects on the bones are seen in lepromatous leprosy and tuberculoid leprosy, but the effects of tuberculoid leprosy on bones occur much earlier and more intensively than does lepromatous leprosy (Ibid.). Leprosy has been found to affect the tibia and fibula (Aufderheide and RodríguezMartín 1998). Here it produces pitting and longitudinally striated subperiosteal bone deposits. The lateral surface of the tibia also exhibits vascular grooves. The fibula is not as affected as the tibia. These changes often occur bilaterally and symmetrically in the tibia and fibula and are more prominent in the distal third portion of the bones (Ibid.). 31 2.5.3 Tumors Treponemal disease can be very similar to many types of tumors also seen within the bones of an individual. The different tumors discussed here are osteosarcoma, meningioma, metastatic carcinoma, and multiple myeloma. Osteosarcoma is a malignant tumor that develops from the connective tissue of bone. In ancient remains they are most commonly found in individuals under the age of 30 and males are affected more often than females (Aufderheide and Rodríguez-Martín 1998; Ortner 2003). This tumor is found in long bones, most commonly the proximal femur and the head of the humerus. Osteosarcoma may also affect individuals over the age of 30. In this group, the tumor affects the flat bones and the skull, with the mandible frequently affected (Aufderheide and Rodríguez-Martín 1998). New bone formation may occur sometimes resulting in the appearance of an “onion skin.” Bone spicules that lie perpendicular to the affected bone surface may also occur. This characteristic is known as a ‘sunburst effect’ (Ibid.). Meningioma is a soft tissue tumor that affects the membranes of the brain and spinal cord. The skeletal evidence for these tumors can be found in the spine, but most are found inside the cranium. This tumor more commonly affects older individuals with the average age being 45 years (Aufderheide and Rodríguez-Martín 1998). Most of these lesions are found on the interior of the skull vault with hyperostosis occurring on the exterior above the lesion. The hyperostosis may be so pronounced that it causes a thickening of the skull. A spiculated appearance may result from these changes (Ibid.). Metastatic carcinoma is a malignant tumor occurring most commonly in individuals over the age of 40. The vertebrae, pelvis, ribs, major long bones, sternum and 32 skull are the most commonly affected bones found in individuals suffering from this type of tumor (Aufderheide and Rodríguez-Martín 1998). Characteristics to look for in the archaeological record are pathologic fractures and vertebral collapse with multiple bone lesions (Ibid.). Multiple myeloma is a malignant tumor usually occurring in individuals over the age of 40 and more often in males than females (Ortner 2003). The lesions of this tumor are strictly lytic, restricted to a particular area, small and round, resorbing bone instead of producing new bone and having a scalloped edge (Aufderheide and Rodríguez-Martín 1998; Ortner 2003). Most often the lesions are seen in the flat bones, particularly the skull. In the skull, the lesions can occur internally, externally or both. Eventually the inner and outer table of the skull is penetrated, resulting in a punched-out appearance. In the later stages of the disease, the lesions may affect the long bone metaphyses, especially in the femur and humerus, and collapse of the vertebral body may occur (Aufderheide and Rodríguez-Martín 1998; Ortner 2003). The most commonly affected bones are the vertebrae, ribs, skull, pelvis, femur, clavicle, and scapula (Aufderheide and RodríguezMartín 1998). 2.5.4 Osteomyelitis Osteomyelitis is an infection within bone and bone marrow caused by bacteria that commonly produce pus (Aufderheide and Rodríguez-Martín 1998). It is distinguished from periostitis by the involvement of the marrow cavity. The most commonly affected areas are those of the knee, distal tibia, proximal femur, and sometimes the humerus is affected (Ibid.). All age groups and any part of the skeleton 33 can suffer from osteomyelitis (Ortner 2003). In children, usually the proximal and distal ends of the bone are affected, the areas where growth occurs. In adults the ends of the bones as well as the shafts are affected (Aufderheide and Rodríguez-Martín 1998). Osteomyelitis usually only affects one bone, although multiple bones can be involved. The bones become enlarged and deformed through the processes of destruction of the bone and bone formation. Osteomyelitis is characterized by an area of dead bone that is surrounded by new bone and has a cloaca (hole) that allows pus to drain from the infected area. The dead bone is known as a sequestrum, while the new bone is an involucrum. Healing may occur, but some pitting and cavities will remain in the affected bone (Ibid.). Osteomyelitis is not commonly found in the bones of the hands and feet. If it does occur, an expanded involucrum will result which resembles changes found in congenital syphilis and tuberculosis found in children. In adults the foot phalanges are more apt to be involved (Ortner 2003). Osteomyelitis is not commonly found in the vertebrae. If it does occur, adults are affected more often than children, and usually only one vertebra is involved. The cervical vertebrae are most commonly involved with the sites of infection in the neural arch and spinous processes (Ibid.). It is also rare to find osteomyelitis in the skull. When it does occur, the most common area is that of the frontal bone. The infection will cross sutures, spreading throughout the cranial vault and into the parietals, but the occipital is rarely involved. The outer table is usually affected more than the inner table (Ibid.). Middle ear infections can result in osteomyelitis affecting the mastoid, temporal, and petrous bone, and the mandible and maxilla can also be affected (Ibid.). No matter what bone is affected, osteomyelitis is characterized by the presence of a sequestrum and an involucrum. 34 2.5.5 Paget’s Disease The cause of this disease is unknown. Paget’s disease is characterized by both bone resorption and new bone formation that occurs simultaneously. The most common age group affected is those individuals over the age of 60, and males are more commonly affected than females (Aufderheide and Rodríguez-Martín 1998; Ortner 2003). Bones that are affected most commonly are the pelvis, femur, skull, tibia, vertebral column, clavicles and ribs. The fibula and the bones of the hands and feet are usually not involved (Ortner 2003). In the skull, both the inner and outer tables are thinned. In later stages of progression, new bone is produced on the inner and outer tables and also within the diploë. This phase may last for many years, producing a thickening of the cranium 23 cm in depth (Aufderheide and Rodríguez-Martín 1998). The infection usually crosses over the suture lines (Ortner 2003). The facial bones generally are not affected, but when they are, severe deformity is the result (Aufderheide and Rodríguez-Martín 1998; Ortner 2003). Paget’s disease affects all areas of the vertebrae, mostly the lumbar, but the most noticeable changes occur on the vertebral body (Aufderheide and Rodríguez-Martín 1998). The center of the vertebral body may become depressed, fusion of adjacent vertebral bodies may occur, and the outer edges may also become widened and dense (Ibid.). The long bones may also be affected by Paget’s disease. A thickening of the cortex occurs, but the medullary cavity is left intact, although it may become narrowed (Ortner 2003). Bowing occurs from the deposition of new bone on the femur 35 anterolaterally and on the tibia laterally. Fractures can also be seen with the most common being fissure-like stress fractures (Aufderheide and Rodríguez-Martín 1998). 2.6 Differential Diagnosis To summarize, these diseases are best differentiated by the profile of effects outlined in Appendix A. Treponemal disease most often affects the skull, hands, tibiae, fibulae, and feet of an infected individual. Tuberculosis most often affects the spine or vertebral column, causing collapse of the vertebral body(s) of an individual. Tuberculosis can also affect the skull, but unlike treponemal disease, there is usually only a single lesion affecting both the inner and outer tables with very little, if any, bony reaction and irregular margins that are destructive in nature (Mitchell 2003). Tuberculosis destroys bone while treponematosis produces new bone. Treponemal disease produces a general increased swelling of the diaphyses in long bones, whereas tuberculosis does not (Steinbock 1976). Treponemal disease produces multiple lesions, a larger area of involvement in the long bone shafts, an altered medullary cavity, an uneven cortex with bone formation and destruction unlike the changes seen in tuberculosis (Steinbock 1976). Leprosy affects the maxillary bone, palate, hands and feet of an individual through the resorption of bone. In treponemal disease there is a remodeling and formation of bone, whereas in tuberculosis and leprosy there is a resorption of bone. Treponemal disease can also affect the spine, but it affects the cervical vertebrae more 36 commonly, whereas tuberculosis more commonly affects the thoracic and lumbar vertebrae. Other things to consider for a differential diagnosis between treponemal disease and tuberculosis or leprosy are the distribution of lesions within the population. Tuberculosis skeletal lesions are found in 1% of the population (Aufderheide and Rodríguez-Martín 1998), while periosteal reaction greater than 2% of the population is considered to be treponemal disease (Rothschild et al. 2004). Proliferative lesions are not as common in leprosy because of the resorption of bone and leprosy only affects 5% of the skeleton (Ortner 2003). A higher frequency of skeletal involvement should indicate a treponemal disease. Nonvenereal treponemal disease has the highest population frequency (20-40%) that involves periosteal reaction (Rothschild 2000). No other disease has a population frequency this high involving periosteal reaction. Venereal syphilis has a low population frequency (14% or less) and because of this reason it is harder to differentiate from other diseases when considering lesions within the skeleton of an individual (Ibid.). Osteosarcoma involves only one bone, while treponemal disease occurs bilaterally in long bones and in older individuals (Aufderheide and Rodríguez-Martín 1998; Steinbock 1976). Meningioma affects the skull, never the postcranial skeleton (Aufderheide and Rodríguez-Martín 1998). Meningioma produces a thickening of the inner and outer tables of the skull and also a widening of the diploë, unlike treponemal disease (Steinbock 1976). Metastatic carcinoma lesions are usually small, not necrotic and regeneration of the bone does not occur. Unlike treponemal disease these lesions are widely scattered and the lesions do not coalesce (Steinbock 1976). Treponemal disease 37 forms new bone growth surrounding the lesions and treponemal disease also exhibits postcranial lesions (Kelley 1980). The lesions occurring in multiple myeloma are lytic lesions and they are smaller than the lesions occurring in treponemal disease (Aufderheide and Rodríguez-Martín 1998). Steinbock (1976) states that the lesions occurring in multiple myeloma are smaller, not necrotic, do not regenerate the bone and are widely scattered lesions that do not coalesce, which is unlike those lesions seen in treponemal disease. Kelley (1980) adds that in treponemal disease there is a formation of new bone that surrounds the lesions and that the lesions of treponemal disease also occur in the postcranial skeleton. Pyogenic (pus-producing) osteomyelitis usually involves fewer bones than treponemal disease. Osteomyelitis also produces the characteristic sequestrum, involucrum, and cloaca in the postcranial skeleton, whereas in treponemal disease these pathologic changes are rarely observed (Aufderheide and Rodríguez-Martín 1998; Steinbock 1976). Osteomyelitis usually does not involve the cranium, whereas treponemal disease does (Steinbock 1976). Kelley (1980) states that osteomyelitis is more destructive than treponemal disease, involving joints more often. Paget’s disease produces massive thickening of the skull vault, while in treponemal disease there is bone formation and bone loss that produces hills and valleys, not an extreme expansion of the diploë (Aufderheide and Rodríguez-Martín 1998). Histologic examination of the bones also reveals the mosaic pattern of Paget’s disease that is not found in treponemal disease (Steinbock 1976). Kelley (1980) states that Paget’s disease and treponemal disease differ in the age of onset and that Paget’s disease is a localized infection that lacks cloacae, whereas treponemal disease is widespread and 38 may occasionally possess cloacae in the postcranial skeleton. Paget’s disease can produce periosteal reaction but the frequency is never greater than 1% in individuals under the age of 40 years (Rothschild 2005). In Paget’s disease, cortical thickening of the tibia occurs on the posterior portion, while in treponemal disease, cortical thickening occurs on the anterior portion of the tibia (Ibid.). 2.7 Objectives In summary, there are several hypotheses revolving around the geographic origins and development of treponemal disease. Did it originate in the New World or the Old World? Was Columbus’ voyage responsible for bringing it to Europe, where it became more virulent? Has it always been present in the genus Homo and migrated with humans as they moved to new lands? Is it one disease that transforms depending upon the environment and social factors of the human host or is it several different organisms that are very similar? Treponemal disease leaves markers on the bones that may be similar to other diseases. These other diseases are tuberculosis, leprosy, tumors, osteomyelitis, and Paget’s disease. Looking at the distribution of lesions within a skeleton and the prevalence of lesions at the population level helps to differentiate between the different diseases that affect the bones. In the pages to come, through the study of an early (Archaic) prehistoric population in North America, the Carrier Mills sample from Southern Illinois, these questions will be addressed; 1) Is there a treponemal disease within this sample?; 2) If 39 there is a treponemal disease, then which one is it?; 3) What does this study tell us about the lifestyle of this population?; and 4) What does this mean in terms of the history and origin of treponematoses? 40 CHAPTER 3 MATERIAL AND METHODS 3.1 Materials 3.1.1 The Sample – Carrier Mills Archaeological District The focus of my research was on the human skeletal remains recovered from the Carrier Mills Archaeological District, which is located in southern Illinois, in Saline County, 2.5 km south of the village of Carrier Mills and north of the South Fork of the Saline River (see Figure 3.1) (Jefferies and Morrow 1982). Excavation of the site was performed in 1978 and 1979 by the Center for Archaeological Investigations at Southern Illinois University, Carbondale (Jefferies and Morrow 1982). There are three major sites; 11SA86, 11SA87, 11SA88, and several smaller sites within the 57 hectares of the district. The Black Earth site (11SA87) is the largest and most complex site (Jefferies and Morrow 1982) and it is the site that contains the human skeletal remains examined in this research. There are three main areas within the Black Earth site: A, B, and C (see Figure 3.2). The skeletons examined in this study are from Area A, which produced the most burials, with 201 burial features containing 223 individuals (Jefferies 1982b). Some of the burials were located in the plow zone and were severely disturbed, while the majority of the burials were recovered from the midden zone, which was undisturbed and located in the central portion of Area A. Most burials date from the Middle Archaic (4500-3000 41 BC) to Late Archaic (3000-1000 BC) periods, but a few have been identified as Woodland period burials (1000 BC – AD 1000) (Jefferies and Morrow 1982). Skeletal preservation for both the Archaic and Woodland period groups is good to excellent as a result of the soil having a high pH level and a good drainage system. The soil also contained high carbonate concentrations that slowed deterioration of the bone, but left hard deposits on the surfaces of the bones (Bassett 1982). These deposits hindered both the initial analysis conducted by Bassett (1982) and the research conducted here. 3.1.2 Burial Sample The burial sample of the Black Earth site (11SA87) has been dated using radiocarbon dating techniques. Eight charcoal samples were analyzed from undisturbed features within the Area A midden. The samples were collected based on their specific vertical positions, so that midden deposition rates could be calculated (Bassett 1982). These charcoal samples produced dates ranging from 3955 to 2910 B.C. (Jefferies 1982a). It is believed that the inhabitants occupied this area from approximately 4000 B.C. to 2900 B.C., due to the dates revealed from the radiocarbon dating (Bassett 1982). The inhabitants were hunter-gatherers who were becoming more accustomed to a sedentary lifestyle, which implies that there was also a gradual increase in the population over time. An increase in population also results in an increase in plant and animal species found in archaeological sites. For these reasons, the Archaic period has been characterized as having an “increasing regional specialization and adaptation marked by the appearance of large, intensively occupied sites” (Jefferies and Morrow 1982;19), and 42 it is also a time when specialized tool forms begin to appear. There is evidence within this Archaic period site of multiseasonal occupation, meaning that this site was probably occupied year-round instead of being a seasonal camp that depended upon the environment and availability of foods (Jefferies and Morrow 1982). The increase in population size along with multiseasonal occupation also suggests that since people were staying in one place for long periods of time, they had to have a place to bury their dead. Therefore, the Archaic period is also the time in which we begin to see archaeological evidence for an increase in the use of cemeteries. Everett J. Bassett (1982) performed the original osteological analysis on all of the Carrier Mills burials (approximately 500 burials). This analysis took place between the years of 1980 and 1982. The general descriptions of the burials as described by Bassett (1982) can be found in Appendix F of The Carrier Mills Archaeological Project: Human Adaptation in the Saline Valley, Illinois, Volume 2. This appendix includes the burial number, cultural affiliation, sex, age group category, estimated age of the individual, preservation/completeness evaluation of the remains, osteitis evaluation, and any other pathological information that was observed by Bassett (1982). Area A contains 237 individuals with 157 dating to the Archaic (4000 – 2900 B.C.) period, 35 from the Woodland (1000 B.C. – A.D. 1000) period, and 45 are of undetermined date (but either Archaic or Woodland). Of the total Archaic period sample, there are 51 juveniles, 54 males, 47 females and 5 individuals that are of undetermined sex. Within the juvenile sample, there are 46 infants (birth to 3 yrs), 4 children (3 to 12 yrs), and 1 adolescent (12 to 20 yrs). There are an additional 6 adolescents (12 to 20 yrs) whose skeletal remains were complete enough to determine sex and are included in the 43 data for males and females instead of juveniles. Of the adult sample, there are 45 young adults (20 to 35 yrs), 49 middle adults (35 to 50 yrs) and 6 old adults (>50+ yrs) within this sample. Males outnumber females in a ratio of 1.5:1. A “treponemal-like” infection has been identified within this skeletal sample (Bassett 1982). Individuals in the sample exhibit some characteristics that are associated with treponemal disease, but these traits may also be associated with other diseases, particularly tuberculosis (Bassett 1982). Bassett (1982) found periosteal involvement, lytic lesions, and saber-shins throughout this sample. The most common bones affected were the long bones and the cranium, but the ribs, vertebrae, scapulae, clavicles, and bones of the hands and feet were also affected. He used osteitis as a general term to describe all bone inflammation, but because it was so widespread, he developed a rating system of slight, moderate and severe to help in the analysis (Bassett 1982). Osteitis indicates that an infection was present at the time of death. In Bassett’s (1982) terminology and analysis, ‘slight’ osteitis meant that the infection is present on the anterior portion of the tibiae; it may also be present on the fibulae, posterior tibiae and the anterior femora with slight periosteal remodeling distinguishable. Bassett’s (1982) category of ‘moderate’ osteitis meant that the infection is also present on the posterior femora, the humeri, radii, ulnae, clavicles, metatarsals, metacarpals, and maybe even the ribs, with saber-shin (an anterior bowing of the tibiae) being noticeable. Bassett’s (1982) category of ‘severe’ osteitis indicated obvious saber-shin, deep lesions visible on the tibiae, other long bones and the cranium. Previous research of the human skeletal remains from the Carrier Mills Archaeological District includes: Miller (1981) on postcranial nonmetric traits, Larsen 44 (1981) on the relationships between the stress indicators of Harris lines and dental asymmetry, Brandon (1986) on dietary inferences through dental analysis, Anderson (1998) on measuring stress through tibial growth patterns in juveniles, Van Arsdale (1998) on the sexual division of labor through the patterns of vertebral osteoarthritis, and Clapper (2006) on activities based on musculoskeletal stress markers. This research will explore the tentatively identified treponemal disease within the Archaic period group. 3.2 Methods This study was conducted in 2006-2007 at the Center for Archaeological Investigations curation facility in Carbondale, Illinois, where the sample from Area A of the Black Earth site of the Carrier Mills Archaeological District is housed. The entire sample of Area A individuals was sorted according to cultural affiliation (e.g. Woodland [1000 BC – AD 1000] or Archaic [4000 – 2900 BC] periods). The Archaic period sample of 157 individuals was then sorted numerically according to burial number. The sub-sample (54 individuals) that was visually examined were the first 54 individuals excavated from the Archaic period. Table 3.1 gives the categories (e.g. infants, young adults, males, females, etc.) and the percentages of the individuals in the total sample (157) versus the percentages of individuals from the sub-sample (54). Also compared from the total sample and the sub-sample in this Table are the numbers of males, females, and juveniles, the numbers of individuals diagnosed by Bassett (1982) as having slight, moderate, severe, and no osteitis, and the number of burials that were considered to be complete based on a rating of 1, 2, and 3 with 1 being the least complete and 3 being the 45 most complete. As can be seen from Table 3.1, the percentages of males, females, juveniles, and undetermined from the sub-sample are nearly equivalent to those of the entire sample. The percentage that is lacking the most is that of the juveniles. Figure 3.3 is a map of the Archaic period burials. This map indicates that the burials were widely distributed throughout the entire Stratum 1 area of the site, the core area. The central and western portions of the Stratum 1 layer of Area A contain the most burials. This map contains all but five individuals from the sub-sample (54) used in this study. On the original map of all of the Archaic burials, there were a few outliers to the North, South and West along the trenches for this site. This map has been cropped to show a closer view of the densest concentration of burials, or the core area of the site. Another reason why the map lacks the total number of Archaic burials (157) is that some burials were left out of the initial analysis by Lynch (1982) due to preservation issues. Only 124 burials were analyzed and plotted on the map. It is apparent that by sampling the first 54 individuals, the subsample included individuals widely distributed across the site except in the southeast quandrant. There was nothing distinct or different about the site preservation, burial context, or mixture of individuals in that quadrant (Brian Butler, personal communication). Bassett’s (1982) age assessment for the juveniles was based on five criteria: dental calcification, occipital development, long bone length, dental eruption, and the union of epiphyses. Each individual was also assigned an approximate error factor depending on the estimated age of the individual (Bassett 1982). Sex determination was not attempted for the juveniles. 46 Adult age estimation, as assessed by Bassett (1982), was based on five criteria of progressive changes in the human skeleton. These changes occur in areas of the auricular surface, pubic symphysis, cranial suture closure, functional dental wear, and involution of the cortical and trabecular bone of the proximal femur. The most useful indicators were the auricular surface, because it has the most variation and is preserved more frequently in the Carrier Mills sample, followed by the pubic symphysis, the second most preserved indicator in the sample (Bassett 1982). Adults missing all of the aging indicators due to poor preservation were separated into 3 different age categories: 18-35 years, 35+ years, and 18+ years depending on the amount of skeletal degeneration related to age. Each individual was also assigned an approximate error factor depending on the estimated age of the individual (Ibid.). Sex indicators utilized by Bassett (1982) for the adults were the characteristics of the pelvis, skull, and postcranial robusticity. The most useful indicators are those of the pelvis. Three non-metric methods were used for the pelvis: “1) the ventral arc of the pubis, the subpubic concavity, and the medial aspect of the ischiopubic ramus, 2) the sciatic notch, and 3) the feminine preauricular sulcus” (Bassett 1982:1039). The characteristics of the skull utilized to indicate the sex of the individuals were: “1) development of the nuchal ridges, 2) presence or absence of the external occipital protuberance, 3) mastoid size, 4) robusticity of the mandible, and 5) presence and size of the supraorbital ridges” (Bassett 1982:1039). 47 Individuals with ambiguous, contradictory, incomplete, or poorly preserved characteristics were assigned Male (?), Female (?), or just a simple (?). A sub-sample of 54 individuals from the Archaic (4000 – 2900 B.C.) period sample was examined, in this study. Of the 54 individuals, nine are infants (birth to 3 yrs), two are adolescents (12 to 20 yrs), nineteen are young adults (20 to 35 yrs), twenty are middle adults (35 to 50 yrs), and four are old adults (>50+ yrs). These age categories follow the standard age categories as described by Buikstra and Ubelaker (1994). There are twenty-six males: 1 adolescent, 12 young adults, 12 middle adults, and 1 old adult; seventeen females: 1 adolescent, 6 young adults, 7 middle adults, 3 old adults; nine juveniles, and two individuals of undetermined sex: 1 young adult and 1 middle adult, which results in the same ratio of 1.5 males to 1 female as that seen in the entire sample. Here, Bassett’s (1982) determination of sex and age were used as a reference point for the specimens and initial estimate. However, Bassett’s work was not tightly focused, due to his research being broad, including determining such factors as sex, age, disease, demography, growth, stature, dating techniques and a general description of the burials from the entire Carrier Mills Archaeological District, which consists of nearly 500 skeletons. Therefore, his sex determination and age estimates were reevaluated, resulting in some changes during this analysis. Of the 54 individuals in this research, the sex determination for five of them was changed. Burials 45, 66, 84, 86, and 89 were originally identified as male, but were reclassified as female based upon wide sciatic notches, small mastoids, and complete perforation of the olecranon fossa of the humerus. Age categories were also changed for eight of the 54 individuals. Burials 29, 45, and 94, originally categorized as young 48 adults, were changed to middle adults. Burial 50 was originally a middle adult and was changed to a young adult. Burials 66, 100, and 114, originally adolescents, were changed to young adults. Burial 103, a middle adult in Bassett's analysis, was reclassified as an old adult. These changes were not due to altered estimates of absolute age but to reconsiderations of the age ranges in each category. For example, Burial 29 was originally classified as a young adult (20-35), but upon examination of the age of the individual, which was determined to be approximately 44 years of age, this individual was reclassified as a middle adult (35-50). During the examination, data were entered into an Excel database using the skeletal code key, following the Standards For Data Collection manual (Buikstra and Ubelaker 1994). The following information was recorded in the Data Collection Worksheet: burial number, skeletal element, side, section, aspect, pathology, lesion location and lesion type. Also noted in the database are additional observations on diagrams, sketches of where the lesions occur if any, photographs taken of the pathological changes, and any comments regarding the examination. The teeth of the nine infants were visually examined, particularly the permanent incisors and permanent first molars, for the characteristic changes of congenital syphilis, including Hutchinson’s incisors, Mulberry molars and Moon’s molars. The canines were examined for evidence of hypoplasias as well. The teeth of the adults were also examined for pathological changes. Any abnormal shape in bone, size and formation, and bone loss specific to treponemal infection was recorded. All bones presenting these features were set aside, labeled and photographed. Photographs were taken throughout the data collection and at 49 the conclusion of the analysis. A Nikon Coolpix 7600 digital camera was used, uploading images into a computer with each image assigned a number, and the number recorded in the database. 3.3 Summary In summary, one third of the Archaic period skeletal sample of the Carrier Mills Archaeological District was examined, specifically those of the Black Earth site, for evidence of treponemal disease. These data were then used to address the following two questions: 1) Is there evidence of a treponemal disease within this sample? and 2) If there is a treponemal disease, which one is it? To determine if there is a treponemal disease in the Carrier Mills skeletal sample, twenty-eight different pathological features were first examined. After determining the presence and absence of these features, it was decided that five primary features should be used to determine the likelihood of treponemal disease within this sample. The five primary traits/markers were decided upon after consulting Ortner (2003) and Bogdan and Weaver’s (1992) diagram showing the distribution of the most frequent sites of skeletal lesions due to treponematoses. These five primary markers are 1) cranial 2) hand 3) tibial 4) fibular and 5) foot involvement. To answer the question of which treponemal disease is present in this sample, a differential diagnosis based on a profile of the effect of treponematoses on populations used by Rothschild et al. (2000) was utilized. This profile highlights the differences between yaws, endemic syphilis, and venereal syphilis through the comparison of cases 50 with confirmed disease. The differences include: hand and foot involvement, adult versus juvenile, and the average number of bone groups affected. In order to examine these questions, the data were summarized based on presence of periosteal and other lesions by: age group, sex, bones included, and uni- or bilaterality. The results of this study are presented in the following chapters. 51 Table 3.1.

The appendix contains the burial number, age/sex category of the individual, completeness of the skeleton, and degree of osteitis that the skeletal remains exhibit. Also contained in this appendix are the notes pertaining to the coding of the human skeletal remains as designated during this analysis. Of the total number of Archaic period skeletons, Bassett (1982) diagnosed 49 with slight osteitis, seven with moderate osteitis, and one male with severe osteitis. Of the subsample of 54 individuals that were examined in this study, Bassett (1982) diagnosed 23 of them with slight osteitis (12 males, 10 females and 1 of undetermined sex), 7 with moderate osteitis (5 males and 2 females), 1 male with severe osteitis, and 23 without any signs of osteitis. While the results presented here are similar in scope of affected individuals, there are some differences and a more detailed understanding of the pattern of affected bones. 4.1 Likelihood of Treponemal Disease 56 Determination of the presence or absence of a treponemal disease and which syndrome is present is based on the presence or absence of osteitis/periostitis changes in different bones and bone groups, by age, sex, and uni- or bilaterality. Tables 4.1 – 4.5 provide an initial summary of the presence of osteitis or other pathological feature of each burial, by bone/bone group, and sex for each age group in the Carrier Mills Archaic sample. All the tables contain the burial number, estimated age in years of the individual, sex of the individual, and the presence, absence, or observability of the 28 different pathological markers used in this study. Markers falling into the five primary sets of features for distinguishing treponemal disease from other diseases are numbered and in bold. These five primary marker sets are: 1) cranial involvement; 2) hand involvement; 3) tibial involvement; 4) fibular involvement; and 5) foot involvement. The tables also contain the number of pathological markers associated with each burial and the number of bone groups affected in each burial. Table 4.1 contains the information for the infants, Table 4.2 contains the adolescents, Table 4.3 consists of the young adults, Table 4.4 is the middle adults, and finally the old adults are in Table 4.5. By looking at Tables 4.1 – 4.5, it is immediately apparent that osteitis and related pathological lesions were widespread in this sample. The Totals column is the total number of individuals affected for each pathological marker. In Table 4.1 (Infants), of the 28 pathological markers, 17 are found on individual infants, while 11 are not. Of the 17 markers found, 10 markers occur on four or more affected individuals. Table 4.2 (Adolescents) shows that 17 of the 28 pathological markers are exhibited on individual juveniles. Table 4.3 (Young Adults) shows that 23 of the 28 pathological markers are exhibited on young adult skeletons; 6 of the pathological markers occur on 10 or more 57 affected individuals. From Table 4.4 (Middle Adults), it is clear that 24 of the 28 pathological markers occur on one or more of these skeletons, and 8 of the pathological markers are found on 10 or more affected individuals. Table 4.5 (Old Adults) shows that out of the 28 pathological markers, 18 affect old adult skeletons, with 13 of those affecting 2 or more individuals. This demonstrates that the skeletal remains for this subsample have a high frequency of bone infection. Table 4.6 contains a summary and the percentages of occurrence for these 28 possible pathological markers (either osteitis on a bone/group or other feature) found within the sample. The data are broken down into the numbers of infants, adolescents, young adults, middle adults, and old adults possessing each marker, but since treponemal disease also affects males more than females, the numbers of males, females, and unknown (adults of undetermined sex) exhibiting each marker are also included. Percentages were calculated based on the number of individuals affected for the juveniles (infants + adolescents), adults, males and females relative to the number preserving that bone for this sample. The adults are affected considerably more than juveniles in this study (see Table 4.6 and Figure 4.1). Focusing on the five primary markers, the cranium is affected far more in the adults (67%) than in the juveniles (36%). The hands are affected far more in the adult (72%) sample than in the juvenile (18%) sample. The bilateral tibiae are more affected in the adult (93%) versus the juvenile (100%) sample. The bilateral fibulae are affected in almost all individuals in which both are present, including 80% of the adults and 67% of the juveniles. Involvement of the feet is also seen considerably more in the adults (78%) than in the juveniles (43%). 58 The results in Table 4.6 indicate that males are generally affected more in this sample than are females (see also Fig. 4.2). Although the frontal/parietal region is affected in fewer males (37%) than females (54%), nasal/palatal involvement was seen in 38% of males, but no females. The hands are also affected more in males (75%) than in females (63%). Bilateral tibiae are affected in almost equal frequency in males (95%) and females (92%). Saber shin, however, is found in 29% of males, but no females. Bilateral fibulae involvement is again about the same in males (78%) than in females (77%). But the feet are affected far more in males (87%) than in females (67%). It is interesting that the male sample is affected more in the hands, feet and saber shin tibia deformity. This could be due to the absence of some of the skeletal elements or to observer error, but as reviewed earlier, treponemal disease generally affects males more than females (Aufderheide and Rodríguez-Martín 1998). The considerable differences in the adult versus the juvenile sample could be due to the frequent absence of hand and foot bones, tibiae, and fibulae in the juvenile sample. Table 4.6 further demonstrates the high level of occurrence of many pathological markers indicative of a treponemal infection, in addition to the five primary markers (in bold), although some (particularly dental features) are conspicuously lacking. While the absence of dental markers could be due to missing permanent incisors and first molars or to attrition in some cases, it may also be indicative that this infection could be nonvenereal in nature. Nonvenereal treponemal disease does not affect the teeth. Table 4.7 is a summary of the likelihood of the Carrier Mills Archaic burial subsample suffering from treponemal disease. Listed are the numbers of burials with a rating system as follows: ‘none’, ‘possible’, ‘highly likely’ and ‘certain’ for suffering 59 from treponemal disease. The ratings are based on the five primary markers of cranial, hands, tibiae, fibulae, and feet involvement. Thus, if a burial did not exhibit osteitis/pathology for any of these five primary areas, the individual was scored not to have a treponemal disease (“None”). If a burial had involvement in one, two or three of these areas, the individual was considered to have “Possible” treponemal disease. If a burial exhibited involvement in four or five of these areas, then it was considered to be “Highly Likely” that the individual had a treponemal disease. A “Certain” for treponemal disease was coded if the individual possessed all five of the markers, had lesions that perforated the cortex, and had the saber shin deformity. If an individual had fewer than five of the primary markers, but exhibited the saber shin deformity, that individual was also considered ‘certain’ for treponemal disease. As has been noted, most of the individuals in this study exhibited infection of the bone on at least one or more elements. Almost all of the 11% of individuals categorized as ‘none’ had at least one bone with osteitis , but since none of the primary marker elements were affected, they were placed in the category of ‘none’. A visual summary of the likelihood of treponemal disease in the Carrier Mills individuals is shown in Figure 4.3. Below is a discussion of the individuals included in each of the likelihood categories based on the five primary marker sets. In discussing individual burials, they will be abbreviated as Burial = B + number (Burial 38 = B38). 4.1.1 Certain Six individuals (11% of the sample) were diagnosed as ‘certain’ for treponemal disease, and all of these were males. The most severe case exhibited all 5 characteristic 60 markers on the skeleton, had lesions perforating the cortex, and had saber shin tibiae. B38 is a middle adult male approximately 40 years old, previously diagnosed as severe osteitis (Bassett 1982). This unfortunate individual had lesions on his entire skeleton. Of the five primary markers used for diagnosis of the skeletons, this individual possessed pathological lesions in all 5 areas of the skeleton: crania, hands, tibiae, fibulae, and feet involvement. This individual also exhibited saber shin deformity of the tibia, which was a bilateral phenomenon. The cranium of B38 exhibits lesions on the frontal, left parietal, left maxilla, left and right mandible, right nasal, left and right lacrimal, and occipital bones. The frontal contains 8 lytic lesions ranging in size from <0.5 cm to 2 cm in length. The left parietal contains ~6-10 small indentations on the top and sides. The occipital has depressions within the lambdoidal suture. The left maxilla has a lesion ~0.5 cm in length above the 2nd and 3rd molars. The mandible has two lesions: one (~1 cm in length) on the right lateral coronoid process that is surrounded by woven bone, and one (~1 cm wide) on the bottom left side close to the mental foramen. The right nasal contains a lesion that is ~ 2.5 cm in length. The lacrimal has one large lesion (~2 cm wide) on the right and five smaller lesions (<1 cm wide for each one) on the left. Figure 4.4 is a drawing of the cranium diagramming the locations of the frontal, parietal, nasal, lacrimal, maxillary, and mandibular lesions. Also seen in this figure is a large abscess above the right first molar. The left mandibular canine also exhibits a hypoplastic defect (not shown). The hands of B38 are also affected. One carpal and the trapezoid of both hands had unifocal bone loss. All of the metacarpals were affected in some way. Most of them had deposition of woven bone and at least one lesion. Some of the hand phalanges were 61 also affected. These were all in the forms of lesions. Figure 4.5 is the left third metacarpal showing one lesion surrounded by woven bone. The tibiae of B38 exhibit bilateral lesions. The right tibia has approximately 10 lesions on the surface that perforate the cortex. They range in size from ~0.5 cm to 1.5 cm wide. Eight of them are surrounded by woven and sclerotic reaction. This tibia also exhibits the most prominent marker of treponemal disease, the saber shin. Figure 4.6 shows the right tibia, posterior midshaft with six lesions surrounded by woven and sclerotic reaction. The left tibia also has approximately 10 lesions on the surface that perforate the cortex. They range in size from 1 to 1.5 cm long. Woven and sclerotic reaction also surrounds eight of them, and it also has the saber shin characteristic. The fibulae of B38 both exhibit lesions, woven bone, and a sclerotic reaction. The right fibula is bowed medio-laterally and it has five lesions, which are all approximately 1.5 cm long. The left fibula has one long lesion (~11 cm in length) that is best described as a cloaca that is surrounded by sclerotic reaction. Figure 4.7 is a closeup of the lateral left fibula showing the cloacae and the surrounding sclerotic reaction. The feet of B38 are severely infected. Of the tarsals, the right side is affected. The calcaneus has lesions and osteophytes. All the metatarsals of both feet are affected. The right metatarsals have lesions and woven bone. The first metatarsal is fused with the first phalanges. The left metatarsals are swollen with woven bone and sclerotic reaction, trabecular coarsening and cortical thinning. Figure 4.8 shows the plantar surface of the first left metatarsal showing woven and sclerotic reaction. The other five burials are not as severely affected as B38. These five burials are B104, B25, B48, B33 and B65. B104 is a middle adult male of 46 years exhibiting 62 involvement of all of the five primary markers and the characteristic saber shin deformity. In the hands, the metacarpals exhibit bone loss, woven bone and deposition of bone. The hand phalanges also exhibit deposition of bone and bone loss. The carpals exhibit bone loss as well. The tibiae have woven bone and sclerotic response anteriorly as well as striations medially. The left tibia has two lesions on the lateral surface at the proximal end and the saber shin deformity. The right tibia has one lesion proximal laterally and also has the saber shin deformity. The fibulae also exhibit woven bone and sclerotic response along with striations on the entire shafts. The foot phalanges have bone deposition and loss. B25, a young adult male of 33 years, shows involvement of the hands, tibiae, and fibulae. The hands have woven bone on the phalanges along with bony growths. The metacarpals are misshapen, like they have been twisted. The right tibia has a concentration of woven bone on the anterior midshaft along with the saber shin deformity. The left tibia has striations, osteitis, and the saber shin deformity. B48 is a young adult male, aged 20-35 years, possessing markers on the tibiae, fibulae, and feet. The right tibia exhibits striations on the shaft medially and the saber shin deformity. The left tibia has striations medially on the shaft and has a patch of woven bone on the distal 1/3 of the shaft along the postero-medial surface, as well as the saber shin deformity. Both fibulae exhibit striations along the entire shaft. In the feet, the tarsals have bone loss and the fifth intermediate and distal phalanges are fused on one foot (side unclear). B33 is a middle adult male, 35 years of age. This particular individual has involvement of the palate, hands, tibiae, fibulae, and feet. There is pitting on the palate. 63 Three hand phalanges exhibit unifocal bone loss. The right tibia exhibits a slight saber shin, with both tibiae having striations on the medial shaft but no apparent thick spongy growth on either tibia. The fibulae have striations on the shaft and are flattened, while the right fibula has sclerotic reaction on the medial surface of the distal shaft. The metatarsals have bone loss and woven bone present. Both ulnae are bowed at the distal end. B65 is a middle adult male of 49 years who exhibits involvement of the hands, tibiae, fibulae, and feet. The intermediate and proximal hand phalanges look swollen and have spicules along the shafts. The right tibia has the saber shin deformity, a thick spongy patch of bone on the medial surface of the proximal end, and striations on the medial shaft. The left tibia is missing. The fibula is not smooth, but exhibits osteitis that is bubbly in appearance. The metatarsals have bone loss, woven and sclerotic reaction on the shafts. Both ulnae and radii are bowed on the distal end. 4.1.2 Highly Likely Out of the 54 individuals examined, 15 (28%) were scored as ‘highly likely’ for displaying pathological lesions consistent with treponemal disease. One of the infants fit into this category with four of the primary markers. B32 (age 0.8 yrs) had cranial, tibial, fibular, and foot involvement. On the cranium, the left orbit exhibits extensive woven bone, while the left temporal also has extensive woven bone present. The tibiae from B32 exhibit woven bone, as well as the fibulae. One of the adolescents, B89 (female, 16 years), had four of the five primary markers, including involvement of the hands, tibiae, fibulae, and feet. 64 Of the young adults, three were ranked as ‘highly likely’ for having treponemal disease, with each having four of the five primary markers. These three burials are B35, B82, and B84. B35 (male, 21 years) had involvement of the crania, hands, tibiae, and feet. B82 (undetermined sex, 25 years) had involvement of the hands, tibiae, fibulae, and feet. B84 (female, 29 years) had involvement of the crania, hand, tibiae, and fibulae. Six of the middle adults were ‘highly likely’ to have been affected by treponemal disease. Four of these burials had four primary markers, B7, B91, B99, and B110. B7 (female, 47 years) exhibited involvement of the crania, hands, tibiae, and feet. B99 (female, 35 years), and B110 (male, 36 years) both exhibited involvement of the hands, tibiae, fibulae, and feet. B91 (male, 42 years) had involvement of the crania, hands, tibiae, and fibulae. The other two burials had five of the primary markers, B86 (female, 35 years), and B93 (male, 42 years). Although B86 and B93 possessed all five traits, they were not categorized as certain for having a treponemal disease because neither of them showed signs of saber tibia. All four of the old adults were categorized as ‘highly likely’ for suffering from treponemal disease. B1 (female, 56 years), and B4 (female, 58 years) possessed all five primary markers, but again they were not categorized as ‘certain’ for having a treponemal disease because neither of them showed signs of saber tibia. The other two burials, B51 (male, 51 years), and B103 (female, 53 years), both had involvement of four of the primary markers: hands, tibiae, fibulae, and feet. 4.1.3 Possible 65 The majority of the individuals in this study were considered ‘possible’ for treponemal disease (28 out of 54, or 52%). Individuals with one, two or three of the five primary marker sets were categorized as ‘possible’ for having suffered from treponemal disease. Of the infants examined, five were scored as ‘possible’ cases for treponemal disease. B77 (1.3 years) had hand involvement, while B30 (0.2 years) and B40 (0.6 years) both had cranial involvement. B62 (0.4 years) had cranial and tibial involvement, while B87 (0.8 years) had tibial and fibular involvement. One of the two adolescents was scored as ‘possible’ for suffering from treponemal disease. B116 is a male of approximately 16 years of age. He possessed two of the primary markers; involvement of the fibulae and feet. Twelve of the young adults were scored as ‘possible’ for suffering from treponemal disease. Three young adults all exhibited only one of the primary marker sets. B39 (male, 22 years) and B109 (female, 21 years) both had hand involvement. B83 (female, 20 years) had tibial involvement. B69 (male, 29 years) possessed two of the primary markers, involvement of the hands and feet. The other eight of the young adults all possessed three of the five primary markers. B66 (female, 21 years) had cranial, tibial, and fibular involvement. B105 (male, 27 years) had involvement of the hands, fibulae, and feet. B50 (male, 34 years), B95 (male, 34 years), and B100 (male, 20+ years), B111 (female, 22 years), B113 (male, 26 years), and B114 (male, 20 years) all possessed markers on the tibiae, fibulae, and feet. Ten of the middle adults were scored as ‘possible’ cases of treponemal disease. Four of these ten possessed two of the primary markers. B29 (male, 44 years) had cranial and tibiae involvement. B85 (female, 40 years) had involvement of the fibulae and feet. 66 B94 (undetermined sex, 44 years) had involvement of the hand and foot. B121 (male, 39 years) had cranial and hand involvement. The other six individuals all had three of the five primary markers. B17 (female, 50 years) exhibited involvement of the tibiae, fibulae, and feet. B45 (female, 37 years), B49 (male, 46 years), and B72 (male, 38 years) all suffered from hand, tibiae, and fibulae involvement. B106 (female, 47 years) had cranial, tibiae, and fibulae involvement, while B124 (male, 42 years) exhibited involvement of the hands, tibiae, and feet. 4.1.4 None Of the 54 individuals examined, 5 (9%) were scored as having no signs of treponemal disease, although these individuals did exhibit infection. Of the infants examined, B21 (1.7 years), B46 (0.1 years), and B63 (0.4 years) did not contain any of the five primary markers and therefore were scored as ‘none’ for having treponemal disease. Two of the young adults were scored as ‘none’ for suffering from treponemal disease. B3 (male, 27 years) and B41 (female, 18-35 years) did not have any of the five primary markers. 4.1.5 Differential Diagnosis and Summary There are five other diseases that have often been difficult to differentiate from treponemal disease in prehistoric populations: tuberculosis, leprosy, tumors, osteomyelitis, and Paget’s disease (see Chapter 2 for specific descriptions). As reviewed above, tuberculosis affects the spine of individuals; more than 40% of the skeletal lesions are seen in the spine (Aufderheide and Rodríguez-Martín 1998). 67 Most commonly the thoracic and lumbar vertebrae are affected. Collapse of the vertebral column may occur, usually involving, but not limited to, two or three vertebrae. The hip, knee and ribs may also be affected (Ibid.). In this study, some of the cervical, thoracic and lumbar vertebrae are affected in all of the age categories. The vertebrae that are affected do not have abscesses that progress horizontally to cause collapse of the vertebral body. Most of the vertebrae exhibit signs of degenerative arthritis and, in some cases, Schmorl’s nodes. Cranial involvement is generally characteristic of treponemal disease and not tuberculosis. In tuberculosis a single lesion that affects the inner and outer tables is often seen. This lesion is not accompanied by any bony reaction. In the cranial lesions observed in this study, there are multiple lesions affecting the outer table and they are accompanied by bony reaction. Leprosy (Lepromatous) most often affects the face in individuals (see Chapter 2). It causes a resorption of bone in the nasal spine. Leprosy also causes erosion of the maxillary bone and the palate, and it also affects the hands and feet. In this study, none of the individuals exhibited resorption of the nasal spine or of the vertebral column. The hands and feet of the individuals in this study were affected, but resorption of the distal phalanges of the hands was not seen, nor was the diagnostic club-shaped foot of leprosy recognizable in the feet of the individuals in the Carrier Mills sample. The lesions occurring in the individuals of this study also do not fit the profile outlined above (Chapter 2) for various tumors. Osteosarcoma involves only one bone, meningioma never affects the postcranial skeleton, metastatic carcinoma and multiple myeloma produce small lesions without regeneration of bone and the lesions are not necrotic. The individuals in this study have lesions that are large, surrounded by 68 regeneration of bone with some necrosis, and the lesions are multiple affecting the cranial and postcranial skeleton. Osteomyelitis produces sequestra, involucra, and cloaca in the postcranial skeleton and does not usually affect the cranium. In this study no sequestra or involucra were observed, and the cranium is affected in some individuals. Paget’s disease produces massive expansion of the skull vault and is a localized infection that may cause periosteal reaction, but this percentage is never greater than 1%. In this study no extreme expansion of the skull vault was observed. The infection in this study is widespread and affects far more than 1% of the sample. Thus it appears overwhelmingly likely that the Carrier Mills sample suffered from some type of treponemal disease. Eighty–nine percent of this sample possessed between one to five of the primary markers for treponemal disease. Some form of periosteal involvement was observed in all but one individual from this study, and this individual (Burial 41) was not complete. Now that it has been determined that a treponemal disease did exist in the Carrier Mills Archaeological District sample, the differential diagnosis of which syndrome of treponemal disease existed at Carrier Mills will be examined and determined. 4.2 Type of Treponemal Disease Distinguishing between the different syndromes of treponemal disease is a very hard task. Many of the bony alterations that occur in one syndrome also occur in the other syndromes. The saber shin deformity of the tibiae can be found in all of the 69 treponematoses that affect the skeleton. Deformity of the nasal-palatal region may also be seen as well as lesions affecting any bone of the body. The lesions are morphologically indistinguishable between the different syndromes. Caries sicca is one characteristic that is not seen in all of the treponematoses. This is the destruction of the cranium produced by venereal syphilis in the tertiary stage. According to Rothschild et al. (2004:64), “periosteal reaction diffusely affecting multiple bones of more than 2% of the population is basically a manifestation of treponemal disease.” A frequency of 2-14% indicates the presence of syphilis, while frequencies of 20-40% indicate the presence of either yaws or endemic syphilis (Rothschild et al. 2004). Rothschild et al. (2000) developed a rubric and summary table of differential diagnosis, relying on the frequency of occurrence in a sample, the ages affected, and the bone groups involved, using a specific set of bone groups. This study will draw on that table to determine which treponemal disease existed in this sample. 4.2.1 Bone Groups Tables 4.8- 4.12 contain data on the different bone groups affected within the sample. The tables are divided into the five different age categories; Table 4.8 is infants, Table 4.9 is adolescents, Table 4.10 consists of young adults, Table 4.11 is middle adults, and Table 4.12 contains old adults. Each table consists of the burial numbers for that age group, estimated age in years, sex of the individual, and then a listing of the bone groups showing osteitis or dental changes characteristic of treponemal disease. The different bone groups included are the nine defined and used by Rothschild et al. (2000): tibiae, fibulae, femora, humeri, radii, ulnae, hand bones, foot bones, clavicles, cranial, 70 plus one additional group added for this study, teeth. The “teeth" group includes only the incisors and the molars. This group is important for distinguishing the different treponemal syndromes; thus it is included in this study. If any bone in a particular bone group is affected, then it is indicated as present with an X. Multiple X’s are used for the hands and feet because the carpals, tarsals, metacarpals, metatarsals, hand and foot phalanges are each considered separate bone groups (following Rothschild et al. 2000). If no member of the bone group is affected, it is indicated with an N. If the bone group was not observable or missing, there is an O on these tables. The number of bone groups affected (marked with an X) for each burial is then totaled. The data presented in Tables 4.8 – 4.12 indicate that there are many bone groups affected in most members of this sample instead of just a few bone groups. This sample is thus polyostotic, meaning that when looking at the bone groups, an average number greater than three are affected (Rothschild et al. 2000). Table 4.13 is a comparison of the numbers of bone groups affected within the Carrier Mills Archaic burial sample and the numbers found in individuals with confirmed cases of syphilis, yaws and endemic syphilis summarized by Rothschild et al. (2000). The numbers of adults and juveniles evaluated are totaled and the percent affected is also shown. The Carrier Mills sample has unilateral tibial involvement, but it also has bilateral tibial involvement, which was not taken into account in the Rothschild et al. (2000) study because two of their five populations were from ossuaries, hindering the assessment of a disease process involving bilaterality of the tibia. Also shown in this table are the age (years before present), of the different sites/samples, average numbers of bone groups affected, whether or not the hands/feet are affected in greater than 5% of the 71 cases, and the distribution or number of individuals affected according to the different bone groups. It is clear from this comparison that the disease process which affected the individuals at Carrier Mills was not venereal syphilis. In fact, it is most like the pattern of involvement seen in yaws, but with far greater expression in terms of both numbers of individuals and average numbers of bone groups affected (see discussion in Chapter 5). 4.3 Comparison of Findings Bassett (1982) found that the most common sites of localized infection for the skeletons of the Carrier Mills sample were the temporal area, the shoulder region, and the tibiae. His findings were consistent for both males and females. The fingers and the os coxae were also affected in males. Bassett (1982) also found widespread infection throughout the skeletal sample, no matter the age or sex of the individuals. This infection consisted of periosteal involvement, lesions, and saber shins of the tibiae. Out of the nearly 500 individuals from the Middle Archaic (4500 – 3000 BC) to the Woodland (1000 BC – AD 1000) periods, Bassett (1982) diagnosed 122 cases of slight osteitis, characterized by slight periosteal involvement of the anterior and posterior tibiae, the fibulae, anterior femora, and slight remodeling of the periosteum. There were 35 cases of moderate osteitis, in which he included periosteal involvement of these same bones but also the posterior femora, humeri, radii, ulnae, clavicles, metatarsals, metacarpals, and in some instances the ribs. A diagnosis of moderate osteitis also included a thick spongy growth on the tibiae and noticeable saber shins (Bassett 1982). The individuals affected 72 the most were classified as having severe osteitis; there were 8 cases of these. This includes all the affected bones from the two previous classifications with the addition of deep lesions on the tibiae, other long bones, and crania. The saber shin became very obvious in these cases as well. Bassett (1982) suggested this infection was non-venereal due to symptoms occurring in young individuals as well as older individuals. The results of the present study mostly agree with the results of Bassett’s (1982) study. There is widespread infection present in all groups of this burial sample. Bassett (1982) diagnosed all infants in this study as having no osteitis. I would disagree. Of the nine infants examined here, 4 have cranial involvement, 3 have tibial involvement, 8 have involvement of the thoracic or lumbar vertebrae, and all 9 have involvement of at least one long bone. This disagreement could be due to difficulties in assessing the normal patterns of bone growth and development in infants. Another area of disagreement centers on the diagnosis of saber shins on some individuals. Bassett (1982) diagnosed Burials 1, 25, 33, 48, 65, 103, and 104 as having moderate osteitis. His diagnosis also included thick spongy growth on the tibiae and noticeable saber shins of these individuals. I did not categorize the disease process on these individuals in precisely the same way. Burial 1 has medial striations on both tibiae, and saber shin was not observed for either tibia. The left tibia did not have thick spongy growth although the right tibia did have spongy growth on the lateral surface of the shaft. Burial 25 does exhibit saber shin tibiae. The right tibia also has a concentration of woven bone at the midshaft that extends from the anterior to medial surface. Burial 33 has a slight saber shin of the right tibia. No thick spongy growth was observed on either tibia. Burial 48 exhibits saber shin on both tibiae. The tibiae both have striations on the shafts 73 medially, but there is not thick spongy growth visible on the right tibia. The left tibia has a patch of thicker spongy growth medial to posterior on the distal third of the shaft that is barely noticeable. Burial 65 has saber shin on the right tibia. There are striations on the medial shaft and a thick spongy patch of bone on the proximal third of the shaft medial. The left tibia is missing. Burial 103 may have slight bowing of the tibiae, but it is so slight that this burial is considered not to have saber shin tibiae. Both tibiae do have striations medially on the shafts, but there is not any thick spongy growth on either tibia. Burial 104 exhibits saber shin on both tibiae. There are striations on the shafts of both tibia medially, there is spongy bone on both anterior shafts, and both have lesions on the proximal shafts lateral, the left has two lesions, while the right has one lesion. Bassett (1982) diagnosed eight individuals with saber shin tibiae and the present study diagnosed six individuals with saber shin tibiae, including Burial 38. Most of the findings in Bassett’s (1982) original study of the Carrier Mills skeletal sample that pertain to the individuals in this sample were confirmed. There are differences pertaining to the infants and to the individuals diagnosed as having saber shin tibiae. These differences can be attributed to observer error (given the large amount of analysis undertaken at once by Bassett) and to the many new advances in paleopathology since 1982. 4.4 Summary Treponemal disease was determined to be present in this sub-sample based on the presence of osteitis/periostitis changes in different bones/groups by age, sex, and uni- or 74 bilaterality of the extremities. Five primary marker sets (cranial, hand, tibial, fibular, and foot) were used to determine the likelihood of a treponemal disease within this subsample. Thirty-nine percent of the sub-sample were categorized as highly likely - to certain for having treponemal disease, 52% were possible for exhibiting treponemal disease, and 9% had indications of a general infection, but were classified as not having had a clear indication of treponemal infection. Rothschild et al. (2004) concluded that 2% or more of a population with periosteal reaction is indicative of a treponemal disease. They also state that a frequency of 20-40% indicates either yaws or endemic syphilis in a population. The results of this study show that 91% of the sub-sample display some kind of periosteal reaction, which is a considerably greater amount than the 2% necessary to indicate treponemal disease. The present study also found that 39% of the individuals were categorized as highly likely - to -certain for treponemal disease. This would fall into the range of the 20-40% (at least) that is indicative of a nonvenereal treponemal infection, like yaws. From the comparison in Table 4.13, the profile of age and bone group involvement make it clear that the Carrier Mills Archaeological District suffered from a syndrome of treponemal disease most like yaws. When Carrier Mills is compared to the confirmed cases of yaws summarized by Rothschild et al. (2004), the number of individuals affected are higher in frequency, with much greater than 5% (in fact 99%) of the Carrier Mills sample affected as a whole (only one individual without evidence of bone disease), and the hands and feet are also affected with a much higher prevalence rate than 5%. Sixty percent of the individuals in this study had involvement of the hands, while 73% had involvement of the feet (see Table 4.6). This is a significant amount, too 75 high of a percentage to be considered venereal syphilis or endemic syphilis. What do these figures tell us about the Carrier Mills sample? In the Discussion and Conclusions Chapter, I will examine more closely: 1) the differential diagnosis of treponemal disease, 2) what life might have been like for the Archaic peoples of Carrier Mills, Illinois, and 3) what this study means in terms of the history and origin of treponemal disease. 76 Table 4.1.

Differentiating between the three syndromes of treponemal disease affecting the human skeletal system can be very challenging. The syndromes yaws, endemic syphilis, and venereal syphilis leave similar periosteal changes on the same bones, for the most part. Rothschild et al. (2000) suggest that an epidemiological approach can discriminate between the different syndromes of treponematoses. This chapter provides an epidemiological approach to discriminating between the different treponematoses as applied to the human skeletal remains from the Carrier Mills Archaeological District. Venereal syphilis was not the syndrome of treponemal disease affecting the Carrier Mills sample. This was concluded from comparing the confirmed cases of venereal syphilis in samples from the Rothschild et al. (2000) study to the present study (see Table 4.13). In the confirmed cases of venereal syphilis, prevalence in the population is small: very few adults have affected bone groups (5%), while none of the juveniles are affected. In the Carrier Mills sample, 98% of the adults have affected bone 110 groups, and 100% of the juveniles are affected. (Note that this comparison is based on the nine bone groups of Rothschild et al. plus teeth, not the five "primary markers" used earlier to indicate any evidence of a treponemal infection). The hands and feet are only affected in fewer than 5% of the sample of the confirmed cases of venereal syphilis. For the Carrier Mills sample, more than 5% of the hands and feet are involved. The average number of bone groups affected in the confirmed cases of venereal syphilis is few, at 1.9 (Rothschild et al. 2000). The average number of bone groups for the Carrier Mills study is much higher at 6.3. On the basis of both adults and juveniles affected, more than 5% of the hands and feet being affected, and the average number of bone groups being greater than 3, the Carrier Mills Archaic sample could not have suffered from venereal syphilis. By comparing the Carrier Mills sample to that of the confirmed cases of endemic syphilis (bejel), it is concluded that endemic syphilis was not the treponemal disease affecting this sample either. In the confirmed cases of endemic syphilis, 25% of the adults are affected and 10% of the juveniles are affected (see Table 4.13). In the Carrier Mills sample, 98% of the adults are affected, while 100% of the juveniles are affected. While it is true that greater than 5% of the juveniles are affected in the confirmed cases of endemic syphilis, it is still a very small percentage compared to ubiquity seen in the Carrier Mills juveniles. The hands and feet are affected in fewer than 5% of individuals of the confirmed cases of endemic syphilis (see Table 4.13). In the Carrier Mills study, the hands and feet are affected greater than 5%. The average number of bone groups affected in the Carrier Mills sample is 6.3, while the average number of bone groups in the confirmed cases of endemic syphilis is much smaller, at 2.0. Based on these figures, 111 endemic syphilis is not the treponemal disease affecting the Carrier Mills Archaic sample. The comparison of the confirmed cases of yaws to that of the Carrier Mills study strongly supports that the Carrier Mills Archaic sample suffered from a treponemal disease most like that of yaws, among known modern treponemal syndromes. In yaws, greater than 5% of the individuals have involvement of the hands and feet, there is a greater frequency of adults and juveniles affected, and the average number of bone groups affected is greater than three (see Table 4.13). This is the pattern seen in the Carrier Mills sample. It is overwhelmingly apparent that a treponemal disease resembling that of yaws affected the Carrier Mills Archaic sample. So what does this tell us about the life of the Carrier Mills Archaic people as compared to other contemporaneous North American sites located nearby and what does it mean in the context of the debate on the origin of treponemal disease? 5.2 Comparisons to Other Sites The findings of this research can now be compared to other nearby or Archaic sites. The first two sites are those of Moundville and Irene Mound. Powell (1991) found similar pathological evidence of nonvenereal treponemal disease at both of these sites. Moundville is a Mississippian (AD 1050-1550) period occupation site located in west central Alabama. The total number of excavated burials from this site is 1500; of these Powell (1991) selected 564 for her study. Irene Mound is also a Mississippian (AD 1110-1400) site located near the mouth of the Savannah River on the Atlantic Coast. 112 Two hundred and sixty-five individuals were selected from this site for analysis. Both of these samples revealed extensive periostitis on the long bone shafts of the tibia, fibula, radius, and ulna, along with saber shin deformity (Ibid.). In the Moundville sample, small, circular depressions were found on the cranial vaults. Skeletons from Irene Mound, on the other hand, exhibited evidence of gangosa. A young adult female from Irene Mound exhibited lesions of the frontal, palate, maxilla and extensive remodeling of the nasal aperture (Ibid.). When Carrier Mills is compared to Moundville and Irene Mound, there are clear similarities. Numerous foci of periostitis along the long bone shafts of the tibiae and fibulae, as well as saber shin deformity are found in the skeletons from all three sites. The Irene Mound skeletons display evidence of gangosa, while those from Carrier Mills do not, although at both Irene Mound (IM) and Carrier Mills (CM) there are lesions on the frontal bones of two individuals (a young adult female (IM) and a middle adult male (CM)). The differences in the disease profile between these sites could be attributed to the time span between the sites; Irene Mound and Moundville are both Mississippian, while Carrier Mills is Archaic. Pete Klunk Mounds in west central Illinois is a Late Archaic (900 BC) site (Cook 2002; Powell et al. 2005). This site only produced 22 individuals, with one of these, a young adult male 18-25 years, exhibiting evidence of treponemal disease. The characteristics of this individual include: thickened and rounded margins of the nasal aperture; small nasal spurs; the floor of the nasal cavity, the bony palate and the lacrimal canals displaying reactive new bone formation; the palate thickened with a small perforation; the anterior nasal spine somewhat resorbed, broad and irregular; and the 113 midline crest irregular, porous and raised (Cook 2002). All of these characteristics can be found in the gangosa deformity of yaws (Ibid.). Pete Klunk Mounds and Carrier Mills do not seem to have many similarities, except for the fact that the most severe case at both sites is male. Cook (2002) concluded that the characteristics found in the young adult male at Pete Klunk were those of gangosa from yaws. None of the individuals examined at Carrier Mills had the gangosa deformity. It is possible that the characteristics visible in the Carrier Mills site belong to a different syndrome of treponemal disease. Perhaps this syndrome is an earlier form of yaws that did not have advanced gangosa deformity. Eva II is a late Middle Archaic (5000-3000 BC) site in western Tennessee with approximately 71 adults and adolescents recovered from the site (Powell et al. 2005). Two burials exhibit characteristics of treponemal disease. Burial 11 is a middle adult male that exhibits the following characteristics: surface pitting, round depressions with radiating striae, and raised areas of bone with multiple shallow round depressions on the frontal and parietals; the palate is perforated; there is periostitis on the ribs, left humerus, left radius, left fibula, right clavicle, both femora, and both tibiae (Ibid.). The second is Burial 36, an adult of indeterminate age and sex, although Powell et al. (2005) state that this was probably a male. This adult exhibits several characteristics: the frontal and right posterior parietal have thickened cortical bone with circular depressions; there are also stellate scars, circumvallate lesions and areas of porosity on the cranium; 6 rib fragments have lesions on the dorsal surface which are circular depressions with woven bone; the left tibia and both femora exhibit nodular cavitation; the left clavicle has lesions that are 114 coalescing and penetrating; the distal metaphysis of the left humerus is thickened; and the midshaft of the right radius has reactive bone and superficial cavitation (Ibid.). Eva II (EII) and Carrier Mills (CM) have many similarities. All three burials with major symptoms appear to be males (EII 11, 36, and CM 38). The frontal and parietals have multiple shallow round depressions and surface pitting, and periostitis is seen in multiple long bones including the femora, tibiae, fibulae, and radii. The frontal lesions of CM Burial 38 show focal superficial cavitation. Powell et al. (2005) conclude that this is a non-venereal treponemal disease due to the fact that there is no evidence found for congenital cases or the characteristic dental stigmata of congenital syphilis. The Barrett site is in the Green River Valley of McLean County, Kentucky. This site includes 412 individuals: 237 adults, 41 children, 101 infants, and 33 individuals of undetermined age. The Archaic site dates to 5620 BP or 4520 BP according to new radiocarbon dates (Powell et al. 2005). Pathological changes in this sample include a high frequency of lesions involving the nasal cavity, palate and face that are resorptive in nature (Ibid.). The palates display pitting and a large incisive foramen. The crania exhibit lesions of the vault that include clustered pits, radial scars, circumvallate cavitation, and confluent clustered pits (Ibid.). The postcranial skeleton exhibits diffuse pitting, linear striations, periosteal plaques, remodeled and active lesions of which the tibia and fibula are the most affected (Ibid.). The skeletal materials from Barrett and Carrier Mills have a few similarities. Again they differ in the characteristics involving the face. The Barrett skeletal collection has many characteristics of the gangosa deformity, while Carrier Mills does not. Carrier Mills Burial 38 exhibits focal superficial cavitation and clustered pits on the cranium, 115 similar to what is seen at Barrett. Both Barrett and Carrier Mills individuals exhibit linear striations, periosteal plaques, and remodeled lesions of the tibiae, fibulae, and femora. The last site is that of Indian Knoll from the Archaic (3352-2013 BC) period located along the Green River in western Ohio County, Kentucky (Cassidy 1972; Powell et al. 2005). This site includes 1234 skeletons (Cassidy 1972). The original analysis of this site was performed by Snow (1948), who concluded that syphilis was present in this population based on 4 affected individuals. Burial 9 is that of a young woman with palatine and maxillae involvement; Burial 13 is that of a young woman whose nasal aperture exhibits scarred, rounded over borders; Burial 508 is that of a young man who has similar characteristics to those of Burial 9; and Burial 490, the most affected individual, has lesions on the frontal, maxillae, hard palate, humerus and radii (Ibid.). The humerus includes sinus formation and drainage, while the radii exhibit “lace-like fenestration” of bone (Snow 1948:506). Cassidy (1972) examined 285 individuals from Indian Knoll; 70 of those were affected in some way, and she diagnosed the characteristics as those of endemic treponematosis. The analysis revealed that 2.4 % of the Indian Knoll individuals were affected from all age groups (see Cassidy 1972 for a complete chart of the individuals affected). The characteristics found include: thickening of the periosteal surface, raised discolored vascular plaques, thickened cortexes, narrow longitudinal striations, smooth billowed areas, and swollen bones perforated by sinuses and bowed (Ibid.). The bones affected include the tibia, fibula, femur, ulna, radius, humerus, clavicle, ribs, zygomatics, and frontal (Ibid.). 116 Kelley (1980) conducted a study of 813 individuals from Indian Knoll. Twentyeight (3.4%) of these individuals were diagnosed as having characteristics of treponemal disease. Eight adults, 4 males and 4 females, between the ages of 20-35 years and 20 juveniles between the ages of 1-3 years exhibited destructive lesions of the nasal, palatal and calvarial bones, bowing and swelling of long bone shafts in children and infants, and saber tibiae (Ibid.). No dental stigmata were found, which the author concluded was indicative of nonvenereal treponemal disease (Ibid.). For a complete list of burials and their characteristics, see Kelley (1980). Indian Knoll and Carrier Mills also share similarities. Both have raised, discolored, vascular plaques, narrow longitudinal striations, swollen bones, bowed bones, sinus formation and saber shin tibiae. Neither site produced any evidence of dental stigmata. In comparing Carrier Mills to these other sites, there are many similarities and there are some differences. The biggest difference is the absence of nasal resorption or the characteristics of the gangosa deformity in Carrier Mills. Perhaps the Carrier Mills individuals suffered from another form of nonvenereal treponemal disease similar to yaws / endemic syphilis suggested for the other sites, but not quite the same. What is clear is that there was a nonvenereal form of treponematosis present and in fact widespread in this sub-sample from Carrier Mills. 5.3 Carrier Mills – Life in the Archaic Period 117 The majority of the burials from the Black Earth site of the Carrier Mills Archaeological District are dated to 4000 – 2900 BC, the Middle to Late Archaic periods. Before inferences can be made about life at Carrier Mills during the Archaic period, it is pertinent to give a general description of the Middle to Late Archaic periods. This description will aid in the understanding of life during the Archaic time period. 5.3.1 General Middle and Late Archaic Period Muller (1986) characterizes the Middle Archaic in the Lower Ohio River Valley as a time of increased sedentism, an increased use of a wider variety of plants, the exploitation of small game, and the cultivation of seeds, all occurring during a much drier and warmer climate than today. The Late Archaic period, according to Muller (1986), was a time when a more complex social and economic organization began to develop but without social distinction between people, and domesticated plants were utilized to a much greater degree. Long-distance exchange systems also began to develop. Evidence of these exchange systems is seen through the presences of such materials as conch shell and copper objects found at Carrier Mills. The Late Archaic was also a period when we begin to see the first archaeological evidence of cemeteries and perhaps (also indicative of increased sedentism), in some areas, the emergence of achieved status (Muller 1986). 5.3.2 Inferences of Life at Carrier Mills Life of the Carrier Mills Archaic peoples must have been very harsh. There were many changes occurring in the environment. People were accessing new resources and 118 learning how to better utilize older ones; small game animals, plants, and nuts. They were discovering that a sedentary lifestyle had fewer benefits than a hunter-gatherer lifestyle. Living in settled groups provided more protection from enemies, and better hunting strategies, but the availability of a broad range of foods decreased. People were forced to rely on certain crops and if these crops failed, malnutrition became a serious problem. Examining the paleopathological evidence from Carrier Mills, it can be concluded that this sample suffered from an endemic treponemal disease, very similar to yaws. This disease affected both juveniles and adults. In this study, the adults appeared to exhibit considerably more advanced stages of the disease than the juveniles, but in the overall skeletal sample of Carrier Mills there is evidence of a high infant mortality rate, with 27% of the population dying within the first year of life (Bassett 1982). It must be remembered that 100% of those dying as juveniles had some expression of bony effects from the disease (or other infection). Yaws is acquired in childhood and is seen more commonly in children and adolescents. In this study, there were not any children (aged 4-11 years) included and there were only two adolescents. Of the 9 infants that were examined, some of them were missing their hands, tibiae, fibulae, and foot bones. These factors could be the reasons why the adults show a considerably higher amount of infection than the juveniles – an artifact of preservation, sampling strategy, and overall illness of the population. Yaws would have been a major stressor in this population. In a study of the juvenile tibial growth patterns of the Carrier Mills sample, Anderson (1998) found that the growth patterns in the Carrier Mills juveniles closely resembled the tibial growth 119 patterns of children from South America suffering from chronic malnourishment. This form of stress then would be chronic, and not episodic, resulting in no recovery period from the stressor. Yaws would have infected this population for long periods of time. Thus, if a juvenile contracted the disease and lived into adulthood, the individual would have suffered through the three different phases of the disease. The individual would have had many lesions on the skin, with some of the lesions excreting pus. Since the disease affected the individual throughout his/her lifetime, there would not be time for periods of recovery from other stressors. In the study of the wild gorillas by Levréro et al. (2007), the third stage of yaws caused deep lesions to occur that cause necrosis of the surrounding tissues. The lesions found in the gorilla population were mainly located on their faces. These deep lesions produced gangosa, which results in death of the tissues of the nose and lips. Some deformities of the jaws were also recorded (Ibid.). Most (70%) of the gorillas suffered from type A lesions which are pinkish, smooth lesions with oozing surfaces (Ibid.). Only 19% of the affected gorillas suffered from type C lesions, which are deep, mutilating lesions. The gorillas with type C lesions exhibited difficulties in chewing, due to the absence of lips, or in some cases deformities of the jaws (Ibid.). Locomotion was also hindered for some of the individuals due to their inability to rest their limbs on the ground because of the lesions. If we look back at this study of Carrier Mills, there are only six individuals with nasal/palatal involvement; 1 is a young adult and five are middle adults. This demonstrates that the individuals would have had the disease for a length of time because these characteristics are occurring in older individuals. Usually it is in the third stage that 120 we see destructive lesions, although in the Carrier Mills study, no extreme cases of gangosa were found. If the individuals were suffering from fleshy lesions on or around the nose and lips, this would hinder their sense of smell and their ability to eat, therefore resulting in chronic malnourishment. If the women were pregnant, suffering from the complications of eating, they would have been malnourished but their babies would have also been malnourished. Maybe this is one of the reasons for the chronic malnourishment found in Anderson’s (1998) study of the Carrier Mills individuals, although the level of oral infection was not high. Van Arsdale’s (1998), study of vertebral osteoarthritis at Carrier Mills found that adult males suffered harsher lifestyles than adult females. In this study, adult males are affected far more than adult females, but both sexes would have suffered consequences in providing for their families. The adult male life in the Archaic period must have been laden with disease, complicated by the stresses of hunting and other activities while dealing with the complications of a treponemal disease similar to yaws. Individuals whose hands and feet were affected would have had complications in walking, picking up tools, making tools, and the many different tasks associated with hunting such as preparing the kill for the journey back to the village. For women, the complications would involve problems with gathering berries, caring for the young, not being able to walk and difficulties in preparing food. Fishing may have also been an important activity for both sexes at Carrier Mills, one made more difficult for the many individuals with infected hands. Other complications that might arise would be with communication. Severe destruction of the face could result in a harsh voice (Powell and Cook 2005). Loss of 121 teeth and the hard palate would result in difficulty in speaking and eating. Nonetheless, the skeletons of most adults overall are those of robust and strong individuals (Bassett 1982; Clapper 2006). Levréro et al. (2007) state that yaws is rarely lethal. In their study of the gorilla population, only one female gorilla disappeared from the population being studied. Other gorillas survived as long as the two years and eight months of the study with serious handicaps (Ibid.). Perhaps then death resulted from general infection or maybe death was the result of chronic malnourishment. 5.4 History and Origin of Treponemal Disease This study of the Carrier Mills skeletal sample contributes to the hypothesis that a non-venereal form of treponemal disease existed in North America at least 3000 years before the present. The majority of the burials from the Black Earth site of Area A are dated to the Middle to Late Archaic, spanning a time period of 4000 – 2900 BC. This means that the most conservative date for the presence of a yaws type of infection in North America would be 4900 years before present, and the earliest date could be 6000 years before present. Therefore, a yaws-like treponematosis was likely in North America long before Columbus and his crew arrived in 1492 AD. Recently Rothschild (2003) suggested that the earliest evidence for treponemal infection similar to yaws was at the Windover site in Florida, 7900 years BP. However, the Windover site has not yet been confirmed as the oldest site in North America exhibiting treponemal disease by any detailed pathological analysis of the skeletal collection. Walker et al. (2005) propose that collections from the Santa Barbara Channel 122 Area of Southern California (4000 – 5000 years ago) are some of the oldest remains exhibiting evidence for treponemal disease in the Western Hemisphere. The presence of a yaws-like treponemal infection at Carrier Mills provides the earliest evidence for treponematosis in Illinois at 6000 – 4900 BP, and perhaps the oldest well-documented evidence in the Western Hemisphere. The second oldest site discussed in Illinois is the Pete Klunk site, which dates to 2900 BP (Powell et al. 2005). Other sites from Illinois include Morton Mounds, Fisher, Parker Heights, Rose Mounds, Gibson, J Gay, L Gay, Ledders, and Yokem all dating from 1000 BC to AD 1000 (Powell et al. 2005). As discussed in Chapter 2, the first hypothesis concerning the origin of syphilis is the “Columbian theory” whose supporters believe that Columbus and his crew brought venereal syphilis back to Europe from the Americas. The Carrier Mills study does not support this hypothesis, as it was a non-venereal form of treponemal disease that existed in this sample, namely yaws. Thus, unless yaws transformed to venereal syphilis in the ships crossing the Atlantic Ocean, Columbus and his crew could not have brought back venereal syphilis from North America to Europe. The second hypothesis, the “Pre-Columbian theory”, suggests that venereal syphilis existed in Europe long before Columbus’ journey to the New World and that Columbus brought the disease to the Americas. As detailed above, this study proves that a non-venereal form of treponemal disease, most like yaws, did exist in North America before Columbus’ journey. The Pre-Columbian theory can only be true if we include the evidence of non-venereal treponemal disease as evidence of the existence of the 123 treponematoses, which could include venereal syphilis, in North America before Columbus’ journey. The other three hypotheses; Livingston’s Alternative Hypothesis, the Unitarian and the Non-Unitarian hypotheses, are all hypotheses suggesting early presence of treponemal disease in the Old World. Was there only a single treponematosis existing in both the Old and New Worlds before Columbus’ journey that evolved into the other syndromes following the evolution of humans through time? Alternatively, was there one treponematosis that began as an animal infection, eventually infecting humans and evolving into the different syndromes of treponemal disease as a result of the pathogen adapting to different environmental circumstances? This study alone does not attempt to answer these questions. Perhaps if we examine a broad range of studies involving treponemal disease, these types of questions can be answered. Therefore, further research into the theories of development of treponemal disease needs to be undertaken. 5.5 Conclusions This study found that a treponemal disease likely did affect the Carrier Mills sample. This syndrome was most similar to that of yaws, but not precisely identical to the pattern of symptoms seen in modern yaws. Other researchers believe that it is possible that another form of treponematosis did exist thousands of years ago (Baker and Armelagos 1988), with many evolutionary changes having occurred since then. We know that gradual change does occur over time within plants, animals and even in bacteria, so it is possible that another form of treponematosis did exist thousands of years 124 ago. This would account for the many similarities found in the Carrier Mills individuals to the treponemal disease of yaws. The treponemal disease in this study is most like yaws, but it is more widespread, occurring in the population far more frequently. It is almost as if this treponemal disease was a “super-" or a "hyper-yaws”. Life in the Archaic of Carrier Mills must have been harsh, with a yaws-like treponematosis affecting all age groups, possibly causing high infant mortality rates but also affecting people throughout their lifetimes. As for the debate on the origin of treponemal disease, this research strongly favors the hypothesis that a non-venereal form of treponematoses existed in North America before Columbus’ historic journey. Therefore, Columbus most likely did not return to Europe with venereal syphilis contracted from the peoples of the Americas. However, it could be possible that Columbus and his crew returned to Europe with a non-venereal form of treponematosis from the Americas, but this would not explain the epidemic of venereal syphilis in 16th century Europe. 125 LITERATURE CITED Anderson LS. 1998.
