God of the residence city Memphis. Originally, Ptah was probably the divine craftsman. This is confirmed by his role as the patron of the workmen in workshops and tomb builders, including at Deir el-Medinah, and by the title of the High Priest of Memphis, who is called the leader of the craftsmen. It is assumed that Ptah acquired his role as creator god through this function. Various sources, for example the Coffin Texts and the Shabaka stone, contain a version of creation by the god using his heart and tongue - thoughts that were spoken came into being. Ptah is also supposed to be the one who designed the Opening of the Mouth ritual. In the Memphite triad, Ptah is the husband of Sakhmet and the father of Nefertem. Imhotep, the deified architect of the Step Pyramid of Djoser in Saqqara, is also considered to be his son. Ptah had close links with various other gods, the best known being Tatenen and Sokar, the funerary god of Memphis. Ptah was linked with the latter since the Old Kingdom, which eventually resulted in the creation of the god Ptah-Sokar. Later on the god Osiris was added, leading to the funerary god Ptah-Sokar-Osiris. Ptah is depicted in human form, with his body being that of a mummy. His hands appear out of the bandages and hold one or more staffs, usually an ankh-sign, a was-sceptre and a djed-pillar. On his head he wears a blue cap. He often stands on a podium in the form of the hieroglyph for Maat.
