Eye of Horus
The ancient Egyptian god Horus was a sky deity, and many Egyptian texts say that Horus's right eye was the Sun and his left eye the Moon. The solar eye and lunar eye were sometimes equated with the red and white crown of Egypt, respectively. Some texts treat the Eye of Horus seemingly interchangeably with the Eye of Ra, which in other contexts is an extension of the power of the sun god Ra and is often personified as a goddess. 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. Other Egyptologists, however, argue that no text clearly equates the eyes of Horus with the Sun and Moon until the New Kingdom (c. 1550–1070 BC); Rolf Krauss argues that the Eye of Horus originally represented Venus as the morning star and evening star and only later became equated with the Moon.
