Egyptian Mythology
This symbol is associated with the falcon-faced Egyptian God Horus. As per the Egyptian mythology, Horus, who was the son of Osiris and Isis, was considered the Sun God. The right eye of Horus was white, and represented the Sun; and the left eye was black, and represented the Moon. Horus lost his left eye to his evil brother Seth, during a fight to avenge the death of his father. Even though, Seth lost the fight, Horus lost his left eye.
