Introduction In the First Dynasty Saqqara Mastaba 3505,Walter Emery found a group of seal-impressions1 in the fill of the staircase and in the nearby east corridor.He classified these seal-impressions and stated that they were the first type(domeshaped and composed of grey-black clay).2 One of the seal impressions of this type had a surface of yellowish colored clay.These seal impressions are preserved because they were inadvertently burnt when the tombs were destroyed.
