Puduḫepa, the wife of Hittite King Ḫattušili III, was a dynamic and influential monarch in her own right. She held an equal position with Ḫattušili III, most likely serving as his co-regent. Her involvement in international relations between Egypt and Ḫatti was significant. Her sealing, along with that of her husband, appeared on the Hittite version of the peace treaty concluded between Ramesses II of Egypt and Ḫattušili III following the Battle of Kadesh. The peace treaty should have required an exceptional seal to sign it, which highlights the significance of studying this seal. Although the actual seal and its sealing have not survived, the ancient Egyptian translation of the Hittite version of the treaty provides detailed descriptions of it. This sealing is unique within the Hittite repertoire of glyptic art. It is of the "Umarmung" type and to date, no other Hittite queen has been known to possess a sealing of this type.
