According to a study in the journal Levant by archaeologists Michael Freikman and David Ben-Shlomo, of the University of Ariel and Yosef Garfinkel of the Hebrew University of Jerusalem, excavations at the prehistoric Israeli village of Tel Tsaf have uncovered a 7,000-year-old piece of clay bearing the impressions of at least two seals inscribed with geometric patterns.
Of the nearly 150 seals that have been uncovered at the Tel Tsaf site, this one is the only stamped one. Additionally, it is the oldest stamped seal ever recovered in Israel.
In the 5th millennium B.C.E., Tel Tsaf wealthy inhabitants had the means to purchase goods from Mesopotamia, Turkey, Egypt, and the Caucasus. According to the research, the stamped seal could be a sign of the region’s rich trade system, and that it was related to administrative practices. A seal would have been used to identify an individual, so it may have been used to authenticate documents.
The stamped seal’s dark grey clay consists of two distinct designs: a geometric impression with nearly a dozen horizontal lines crossing a long vertical one, and another with parallel zigzag lines. An impression of rope on the underside indicates it was “applied to some hard and flat surface bound with rope before being impressed by two or three different seals,” the researchers write. Since it was found in a storage room, they believe it may have been “intentionally kept as a record of previous trade, or as proof of completion of a transaction.”
During previous excavations at Tel Tsaf, pottery, beads, shells, animal bones, and flints, as well as a clay figure resembling a dog have been discovered. There have also been a number of uncovered burials, including one of a woman who was interred with a rare metal awl, obsidian beads, and an ornate belt made of 1,668 ostrich eggshell beads. Additionally, archaeologists have found small pieces of reshaped pottery, which they believe functioned “as mnemonic devices or tokens used to track the amounts and types of stored goods,” according to the Levant paper.
Archaeologists also believed the people who lived there had a surplus of grain, which may have been sold in exchange for certain goods based on the immense storage facilities. Seals like the newly found one may have been used on containers brought in and out of the village to mark them as shipments for transporting that grain. As the written language not yet invented, this stamps would have been an important form of communication, commerce, and property demarcation, especially for the hub of a local trading network.
