Sealing without seals
– an explanation
“Once upon a time...” or rather during the period 30 Aug. – 5 Sept. 1987 was
in Athens held the conference Sixth International Colloquium on Aegean Prehistory. The Prehistoric Aegean and its Relations to adjacent Areas the papers
of which have not yet been published. Fourteen years is a long time and much
research concerning Minoan and Mycenaean seal administration has been
published during those years, while the topic of my paper “Sealing without
seals” has not received much attension. The paper may therefore still be of
interest for those working on Minoan and Mycenaean administration, and I am
grateful to the Centre of Cultural Research at the University of Aarhus for
making it available in their series “Work in progress” and on the Internet.
In the following I present the original paper as it was delivered for the proceedings of the congress. I have, however, added a plan of the LM I settlement
of the GSE and in square brackets [...] given a few comments and references
to relevant publications which have appeared since 1987:

SEALING WITHOUT SEALS
by
Erik Hallager
By the phrase "sealing" is here meant the deliberate securing of the contents
of an object (including a document) in such a way that the "sealing" must be
physically broken to get at the contents.
The finds from the MM IIB Room 25 at Phaistos are a good example of
how the Minoans by the end of the Old Palace period used clay and seals in a
way very similar to that which we find in the Eastern Mediterranean to secure
property and to control access to storerooms. Then, it seems, sealings sealed
objects rather than documents. About 10% of the sealings had secured various
kinds of identifiable goods such as jars or rush matting, while about 90% sealed either flaring wooden pommels or small wooden cylindrical pegs, both
wrapped around with cords. Characteristic for all these sealings is the repeated
use of one seal all over the clay lump which sealed the object or peg.
When we get further down in time in MM III(/LM IA) at Knossos and
Mallia this sealing system seems in part to continue, but two new sealing types
are introduced:
l. A crescent-shaped sealing pierced with stringholes [Single-hole and twohole hanging nodules, cf. Hallager 1996, fig. 2; Schnur-plombe and Schnur-
* I wish to express my gratitude to the Director of the excavation, Dr. Yannis Tzedakis, for his
agreement to the presentation of this material before the final publication, and to Dr. Maria Vlasaki for her agreement to the mentioning of the LM I vases to which the different clay stoppers
fitted. Also a warm thanks to Ms's Helle Vandkilde and Vanna Ninniou for their agreement to the
inclusion of the relevant fragments of pithoi. I wish to thank Dr. Geoffrey Bibby for correcting the
English text. Finally I wish to express my gratitude to the Danish Research Council for the Humanities, which granted me the scholarship under which it was possible to carry out this study.

end-plomben, cf. Müller in Pini 1997, Tabelle 1; CMS 6.2, Tableau 1-2],
which according to Weingarten is the new way of sealing objects – the clay no
longer being pressed against the object [for a different opinion Hallager 1996
I, 197-199], and
2. A flat-based nodule, where the clay has been pressed down directly onto
leather strips which have very reasonably been interpreted as parchment docu-
4
ments [Flat-based nodules, cf. Hallager 1996, fig. 2; Päckchenplomben, cf.
Müller in Pini 1997, Tabelle 1; CMS II.6, Tableau 4].
Those two types in a developed form became the most common types in
the LM I period and we find – again according to Weingarten – : "a change of
emphasis, now on sealings which authenticate, rather than sealings which
prove the storeroom or container is intact".1
When we get down into LM IB it seems that the above two main types,
with the addition of some "unusual clay nodules" [the nodulus] which had not
been fastened to anything,2 were the only sealings in use in the Minoan administration. Such sealings or nodules have been found all over the island and
with this "The switch from Phaistos, from Near Eastern sealing habits, is complete."3
The change is undeniable, but evidence from the Greek-Swedish Excavations at Khania (Fig. 1) may raise the question of whether the change was so
profound as published evidence seems to indicate.
For sealings other than those usually used one may call attention to The
Master Impression, which does not fall into any of the known categories and
which may have sealed a written document rolled up from two ends and bound
by a string which was then sealed.4
Another unusual sealing – also from the GSE – is a triangular clay bar with
twelve seal impressions, ten of which are different.5 We do not know what it
sealed. Dr. Pini has suggested that it was pressed against leather or
parchment. The "package" was securely tied up by several strings, the impressions of which are seen on the reverse.6 This clay bar came from a cupboard

6 It is probable that most of one side of the sealed object was covered by the clay (to judge from
the bent edges). [In Hallager 1996 I, 103 it is argued that the clay bar sealed a large parchment
document].

in our House I, Room D, which also revealed several other interesting sealings.7
One of them showed evidence that objects continued to be sealed, as indicated by a clay stopper (Fig. 9b)8 belonging to a Minoan flask with a broken
rim (Fig. 2).9 That it really sealed the flask although no stringholes were seen
is not only indicated by the seal impressions but also by the thickness of the
fracture along the edge (which also broke one of the seal impressions!), indi7 Among others the two of the "unusual clay nodules" (cf. n.2) [noduli], briefly mentioned in E.

cating that the clay lump had enveloped tightly both the remaining part of the
rim and the handles.
We have two more clay stoppers with seal impressions (Fig. 3).10 They are
of a slightly different type, in that the clay had not only surrounded the rim of
the spout, but was further secured by a string being wound four times over the
stopper before more clay and the seal impressions were added. Those two
stoppers, however, come from LM IIIA:2/IIIB:1 contexts and may not have
been part of the LM I deposits.
If we return to House I, Room D, we shall also find evidence that the
Minoans sealed or secured the contents of containers with clay – but without
using a seal! In 1976 we found two curved triangular pieces of terracotta,11
which had been placed – perhaps with a thin piece of intestine below – on the
flat rim of a small stone vase12 measuring ca. 11 cms in diameter (Fig. 4). The
stone vase, found in 1973, had fallen from a cupboard in Room D.13 Neither

of the two sealing fragments bore traces of seal impressions. It is, however,
surmised that a string around the spout and the opposite handle had passed
through the clay to make it a real "sealing".
Excavating the ruins of the destroyed LM I buildings in the Square we
came in 1984 upon two other fragments of sealings. Both appear to have sealed pithoi. One of them14 had stood upright on the outer edge of a "square-rim"
pithos,and bore the imprints of very rough basketry and clear imprints of fingers from smoothing the clay on the outside (Fig. 5). The other one15 is somewhat different in that it sealed a pithos with another type of rim (Fig. 6). Here

bordering the Square, actually just below the earliest of the LM II layers in the reused street in the
plateia. For this see E. Hallager & Y. Tzedakis, "The Greek-Swedish Excavations at Kastelli, Khania 1984, AAA 18 (1985), 17-18. In Fig. 4 the sealing stands on pithos fragment 84-P 1822 coming
from the same context as the sealing.
15 Excavation no. GSE 84-TC 057, which was also found in the ruins of the LM I houses which
had bordered the square (see further above, n.14). In Fig. 5 the fragment has been placed on the
rim fragment of a pithos GSE 84-P 2011A which was found in the same general context as the
sealing.

the flat side of the sealing is the broader and the smoothing of the clay is found
on the upper part of the sealing. The lid was probably a spirally constructed
mat sewn with strips of palm leaves around the edge, as the impressions in the
clay seem to show. [A few parallels to this type of sealing is found among the
MM II Phaistos sealings.].
Here, then, are found two examples of a sealing procedure where pithoi
were sealed with clay, but where the use of a seal was apparently not needed
to secure the integrity of the contents. Against this it may perhaps be argued
that – as with the sealing on the stone vase – they were not complete, and that
one or more seal impressions may have been present on the missing fragments
– or that the use of clay in the examples given was just a practical precaution
to keep whatever covered the vase or object in place. Furthermore, impressions of strings – which would have indicated that the clay was really intended to seal the pithoi and the stone vase – were not found in any of the three
examples.
But that a sealing procedure without the use of seals was ordinarily practiced in Khania seems strongly indicated by a small clay nodule16 discovered
during the excavation in 1987. It had been incorporated as a pebble in a pebble-floor of the IIIB:2 period, which gives the terminus ante quem. Shape, clay
and fabric, however, strongly recalls another clay nodule with a seal impression, probably of LM I date (Fig. 7a,b).17 The exact date of the nodule found
in 1987 must remain uncertain, but it was clearly used to seal something,
because in the hole which can be seen on its surface was found the imprint of
a knot from a string, and it can be seen how the loose ends from the string had
made small holes in the clay (Fig. 7c,d). Clearly this small clay object had the
same practical function as Weingarten's nodules type 6 to 11, which all secure
a string. And, as is the case with the ordinary nodules, we cannot be sure what
was being sealed by this object.
Apart from the above examples, the GSE has provided definite evidence
that identical objects were secured in an identical way but that seals were rarely used; and here we may return to our House I, Room D, where three more
clay stoppers were found. None of those bore seal impressions, and the vases

This sealing [GSE 84-TC 046; Mus.no. 1565, cf. CMS V, Suppl. 1A, Nr. 146] was actually
found in an LM II context, but may very well have belonged to the destruction level in House IV.

found in a conical cup and might originally have covered the spout of a small
stirrup jar, one of which was found in a neighboring room. The two remaining
clay stoppers20 (Figs. 8a and 9d) could have been placed in larger vessels with
an oval spout – probably flasks or smaller amphorae.
Two of the three stoppers from Room D (Fig. 8a,d) could not have sealed
the vases, but must have functioned as "lids" for the spouts. The third stopper,

Why unsealed stoppers were found in this cupboard without their containers cannot be securely answered. One explanation may be that the room had been looted before being set on fire and
that the containers were removed without their stoppers. Another conjectural hypothesis may be
that the stoppers were intentionally collected and stored in the cupboard, thus very strongly recalling the situation in Room 25 at Phaistos.

seal impressions.
however, (Fig. 9d) had so massive fractures at the side that one must suppose
that the clay had been packed tightly around the broken edge and in this way
functioned as a true "sealing".
Another clay stopper without seal impressions, but whose function as a
true sealing is proved by the string impressions (Fig. 9a), was found in House
I, Room M. It is a stopper of small size21 and could have sealed a small juglet
of a type found in several of the neighboring rooms. One further stopper (Fig.
8b) can be ascribed to Room M. It fitted the spout of an impressive stirrup jar
(Fig. 10).22 This stopper functioned only as a lid in the spout.

Also in House IV two clay stoppers were found, both without seal impressions. Parts of this house were thoroughly disturbed by modern wall foundations, whereby some of its content had been removed. It was, however, possible to fit one stopper (Fig. 8b) into a large stirrup jar (Fig. 11)23 which had fallen from the upper floor. In this case, as in several others where stoppers are
concerned, it was seen to fit a spout which was broken while the vase was still
in use. This too was a "lid" rather than a sealing. The other one,24 however,
appears to have been a true sealing, since a string hole passed through the
upper part on one side and a hole with the imprint from a knot was found on
the other (Fig. 9c).
Securely dated within the LM IB destruction level we have thus discovered 8

clay stoppers,25 four of which functioned only as reusable stoppers or lids (Fig.
8). The remaining four, however, appear to have been true sealings, as indicated by the thickness of the fracture, the stringholes and/or the seal impressions (Fig. 9). Further probable sealings, but without seal impressions, were
those from the pithoi and the small stone vase. True sealings, but of uncertain
date, are the unstamped clay nodule and the two stamped stoppers with stringholes.
The examples given above provide evidence that different objects of
varying sizes continued to be sealed in the Late Minoan I period, but only one
of the stratified "sealings" provided evidence that the contents were secured by
a seal.
25
Several of the stoppers, and especially clearly GSE 78-TC 017, had at the bottom, i.e. the part
inside the spout, clear imprints from being pressed against leather, clearly showing that a small
piece of leather covered the spout before the clay was pressed down into it. I am most grateful to
Dr. Enrica Fiandra who pointed this out to me.
15
Why is it that we have in Khania found continued evidence of direct sealing of objects, and why was the seal used in some cases and not in others? May
this reflect a difference between a household economy and a centralized economy?26 May it be that seals were only needed on objects which had come
from somewhere else?27 or were intended to be send somewhere else? One
may speculate at length on these matters. But it is worthy of mention that the
finds from Khania may perhaps be considered supporting evidence for the
view that seals in LM I authenticate rather than prove storerooms or containers
intact.
However, in the absence – to the author's knowledge – of parallels, it may
be sufficient to conclude that in two individual households in the LM I town
settlement at Khania the practice of sealing objects with clay did continue –
and that it seemed to be the usual practice NOT to secure the contents with the
protection of a seal impression.
26 It may in this connection be worthy of note that actual seals were found in the destroyed LM I
buildings. One small seal of bone (GSE 73-MISC 014; Mus.no. K 28; [CMS V, Suppl 1A, Nr.
121]) was found in House I, Room D, and a lentoid (GSE 74-S 006; Mus.no. L 3181; [CMS V,
Suppl. 1A, Nr. 118]) was found on the floor of House I, Room K. Another one (GSE 8- S 067;
Mus.no. L 3190; [CMS V, Suppl. 1A, Nr. 116]) came from House IV, Room C and a third (GSE
84-S 042; Mus.no. L 3189; [CMS V, Suppl. 1A, Nr. 120]) was found in the ruins East of House I.
For the last two see Hallager & Tzedakis (supra n.14), 13, 19, fig. 5. One further seal stone (GSE
78-S 020; Mus.no. L 3186; [CMS V, Suppl. 1A, Nr. 119]) was found sealed between two floors
of House I, Room H; E. Hallager, and Y. Tzedakis, "The Greek-Swedish Excavations Kastelli,
Khania (1978 and 1979)," AAA 15 (1982), 25. The same phenomenon may be observed in the LM
II deposits in the Unexplored Manson at Knossos, which revealed seals as well as sealings without
a seal, cf. Popham, M., The Minoan Unexplored Manson (BSA, suppl. vol. 17), Oxford 1984, pl.
88a-e.
27 In this connection it seems worthy of note that the clay of the stopper which bore seal impressions seems to be tempered differently from the others.
