Horus the great falcon God, son of Osiris and Isis the child of the holy triad family. His right eye is the sun representing power and true essence of spirit, his left eye the moon representing healing and magic. Horus took revenge on Set his uncle who killed Horus's father Osiris, Set was eventually overcome by Horus but in the melee Horus's left eye (the moon) was damaged. Thankfully, Thoth the great God Of healing and Magic was able to heal it, this became a metaphor to explain the phases of the moon. This moon eye became known as the eye of Horus which represents self-sacrifice, healing, protection and regeneration. It is a sacred holy symbol that has been revered for millennia.
