Ptah is the creator god or maker of things in Egyptian mythology. A patron of craftsmen, especially sculptors; his high priest was called "chief controller of craftsmen." The Greeks identified Ptah with Hephaestus (Vulcan), the divine blacksmith. As the god who created all the other deities, Ptah is worshipped as the patron of craftspeople and architects. He is credited with inventing masonry. The famed architect Imhotep claimed to be his offspring. The Apis bull was considered to be a part of Ptah, and lived in his temple in Memphis.
