عين حورس
The Egyptians often referred to the sun and the moon as the "eyes" of particular gods. The right eye of the god Horus, for instance, was equated with the sun, and his left eye equated with the moon. At times the Egyptians called the lunar eye the "Eye of Horus" and called the solar eye the "Eye of Ra"—Ra being the preeminent sun god in ancient Egyptian religion. Both eyes were represented by the symbol known as the "wedjat" eye, a stylized human eye that incorporates the facial markings of the falcon that was a symbol of Horus. The Egyptologist Richard H. Wilkinson believes the two Eyes of Horus gradually became distinguished as the lunar Eye of Horus and the solar Eye of Ra; however, Rolf Krauss argues that no text equates the Eyes of Horus with the sun and moon until late in Egyptian history, so the Eye of Horus must have originally had some other significance.
