Wadjet (/ˈwɑːdˌdʒɛt/ or /ˈwædˌdʒɛt/; Egyptian wȝḏyt, "green one"), known to the Greek world as Uto (Οὐτώ//ˈuːtoʊ/ or Βουτώ/Buto /ˈbuːtoʊ/) among other names, was originally the ancient local goddess of the city of Dep (Buto). It became part of the city that the Egyptians named Per-Wadjet (House of Wadjet) and the Greeks called Buto (Desouk now), which was an important site in the Predynastic era of ancient Egypt and the cultural developments of the Paleolithic. She was said to be the patron and protector of Lower Egypt and upon unification with Upper Egypt, the joint protector and patron of all of Egypt "goddess" of Upper Egypt. The image of Wadjet with the sun disk is called the uraeus, and it was the emblem on the crown of the rulers of Lower Egypt. She was also the protector of kings and of women in childbirth.
