In his report on the archaic tablets from Jamdat Nasr (=Jemdet Nasr), S. Langdon has given an account of the tablet seal impressions that ‘a large number of tablets are impressed with roll seals, and as in the case of the Elamitic tablets, these impressions are rarely like those of the actual seals found at Jemdet Nasr and Susa.’Three decades after, the excavations controlled by Roger J. Matthews took place in 1988 and 1989, and yielded plenty of artefacts including one cylinder seal of baked clay, 17 sealings and a stamp seal. We have not had any cylinder seal with impressions similar to those of the tablets found by Langdon and of the sealings picked up by Matthews.Why cannot be picked up the cylinder seals with tablet seal impressions from Jamdat Nasr. That is a long-pending problem. This problem awaiting solution is especially important for Matthews who looks through the roles of cylinder seals, and so he examines many impressions of the tablets from Jamdat Nasr. The close examination of the tablet seal impressions that Matthews firstly did, has failed to reveal any traces of wood grain, and subsequently the idea that he has thought out, is that ‘the tablet seal impressions were impressed at some unknown external site whence the tablets … were exported to Jemdet Nasr.’We cannot accept his idea. We suppose that these tablets are impressed in Jamdat Nasr with the wooden cylinder seals, of which designs have some characteristics of wood carving. We can make a conjecture of it, when we compare each stroke of the tablet seal impressions with those of the wooden cylinder seals from the royal tomb of the first half of the Egyptian First Dynasty at Abydos.It may be said at least with certainty that the cylinder seals of wood were used to make impressions on the tablets from Jamdat Nasr. And it will be so with the impressions of the Ur sealings from SIS 4-8 of the Early Dynastic I period.
