Thoth with Wadjet-eye

The most common amulet is the eye of Horus, a human eye with the markings of a falcon's face. Mythology was central to ancient Egyptian magic, and this image is based on the myth of the destruction of one of the falcon-headed god Horus's eyes by the god Seth and its restoration to wholeness (wedja) by the god Thoth, a great magician, The wedjat-eye represented both wellbeing and the constantly renewed victory of the positive forces of the universe over evil or destructive forces.
