Eye of Horus
Horus was an ancient Egyptian sky god in the form of a falcon. The right eye represents a peregrine falcon's eye and the markings around it. This includes the "teardrop" marking sometimes found below the eye. As the wadjet (also udjat or utchat), it also represented the sun, and was associated with the Sun God Ra (Re). The "mirror image", or left eye, represented the moon and the God Tehuti (Thoth).
