Wedjat ring
The wedjat eye is a symbol of the falcon-headed god Horus, who gave the eye to his father Osiris and by doing so brought him back to life. In another story, the eye of Horus was injured and the time required for it to heal was likened to the cycle of the moon. The symbol may be translated as "the whole or restored one."
