Overview
Wadjet (; "Green One"), known to the Greek world as Uto or Buto among other renderings including Wedjat, Uadjet, and Udjo, was originally the ancient Egyptian local goddess of the city of Dep or Buto in Lower Egypt, which was an important site in prehistoric Egypt.
Wadjet was closely associated in ancient Egyptian religion with the Eye of Ra, a powerful protective deity. The hieroglyph for her eye is shown below; sometimes two are shown in the sky of religious images. Buto also contained a sanctuary of Horus, the child of the sun deity who would be interpreted to represent the pharaoh. Much later, Wadjet became associated with Isis as well as with many other deities.
History
Wadjet was said to be the matron and protector of Lower Egypt in her cobra form, and upon unification with Upper Egypt, the joint protector and patron of all of 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. Wadjet was said to be the nurse of the infant god Horus. With the help of his mother Isis, they protected Horus from his treacherous uncle, Set, when they took refuge in the swamps of the Nile Delta.
