The use of seals for both administrative and private purposes to secure rooms, containers, and correspondence reached a high point in the Middle Kingdom, attested by the variety of private and institutional name and pattern seals and the use of complex systems including counterstamping. By comparison, sealing in the New Kingdom seems far simpler, with large assemblages like Malqata the exception, the abandonment of counterstamping and private-name seals, and a shift and apparent simplification in the different seal types used. This chapter compares and contrasts sealing during the two periods, suggesting both taphonomic and administrative reasons for the apparent shift in practices.
