Horus was the ancient Egyptian sky god who was usually depicted as a falcon, most likely a lanner or peregrine falcon. His right eye was associated with the sun god, Ra. The eye symbol represents the marking around the eye of the falcon, including the "teardrop" marking sometimes found below the eye. The mirror image, or left eye, sometimes represented the moon and the god Djehuti (Thoth). In one myth, when Set and Horus were fighting for the throne after Osiris's death, Set gouged out Horus's left eye. The majority of the eye was restored by either Hathor or Thoth (with the last portion possibly being supplied magically). When Horus's eye was recovered, he offered it to his father, Osiris, in hopes of restoring his life. Hence, the eye of Horus was often used to symbolise sacrifice, healing, restoration, and protection.
