 abstract={Archaeological research and architectural studies carried out in the ducal part of the stronghold in Ostrów Tumski in Poznań unearthed remains of a duke’s palace (Fig. 1). A unique clay container was found in a chamber adjoining the palace hall on the north (Fig. 2). Judging by the imprints on the inside walls of the object, it could have been made to protect a seal affixed to a document by a cord (Fig. 3). The surface was stamped with imprints of a crouching dog, guard of the seal. This finding, together with matrices and a lead ducal bulla, suggests the presence of a chancery in the Poznań stronghold, where documents were not only stored, but also drawn up},
