The Eye of Horus
In a savage struggle with Set, Horus's left eye was torn out and shredded. The wisdom god Thoth (Hathor by one account) recovered the pieces one by one and healed and restored it, and this eye made whole again is the "Eye of Horus," the wedjat. It became ancient Egypt's most powerful amulet, a sign of healing, wholeness, and protection, seen everywhere on amulets, coffins, and offering lists. The six parts of the eye were even used as fraction signs. An eye lost and regained in violence became the whole civilization's token that what is broken can be repaired.
