The Eye of Ra or Eye of Re, usually depicted as sun disk or right wedjat-eye (paired with the Eye of Horus, left wedjat-eye), is an entity in ancient Egyptian mythology that functions as an extension of the sun god Ra's power, equated with the disk of the sun, but it often behaves as an independent goddess, a feminine counterpart to Ra and a violent force that subdues his enemies. This goddess, also known with the theonym Wedjat, can be equated with several particular deities, including Hathor, Sekhmet, Bastet, Raet-Tawy, and Mut. The eye goddess acts as mother, sibling, consort, and daughter of the sun god. She is his partner in the creative cycle in which he begets the renewed form of himself that is born at dawn. The eye's violent aspect defends Ra against the agents of disorder that threaten his rule. This dangerous aspect of the eye goddess is often represented by a lioness or by the uraeus, or cobra, a symbol of protection and royal authority. The disastrous fury and rampages of the eye goddess and the efforts of the gods to appease her are a prominent motif in Egyptian mythology.
The Eye of Ra was involved in many areas of ancient Egyptian religion, including in the cults of the many goddesses who are equated with it. Its life-giving power was celebrated in temple rituals, and its dangerous aspect was invoked in the protection of the pharaoh, of sacred places, and of ordinary people and their homes.
