In Ancient Egypt, where the earliest written cultural records exist, the serpent appears from the beginning to the end of their mythology. Ra and Atum ("he who completes or perfects") became the same god, "Atum", the "counter-Ra", associated with earth animals, including the serpent: Nehebkau ("he who harnesses the souls") was the two-headed serpent deity who guarded the entrance to the underworld. He is often seen as the son of the snake goddess Renenutet. She often was confused with (and later was absorbed by) their primal snake goddess Wadjet, the Egyptian cobra, who from the earliest of records was the patron and protector of the country, all other deities, and the pharaohs. Hers is the first known oracle. She was depicted as the crown of Egypt, entwined around the staff of papyrus and the pole that indicated the status of all other deities, as well as having the all-seeing eye of wisdom and vengeance. She never lost her position in the Egyptian pantheon.
