The Egyptian god Seth was the brother of Isis and Osiris, and like them he was the son of the sky goddess Nut and the earth god Geb. Seth is the dark side of his brother and sister – Isis makes the crops grow, and Osiris is the god of the Pharaohs who maintain order, but Seth is the god of chaos. In some stories, Seth showed his bad side by ripping his way out of his mother’s side to be born instead of being born the normal way.
In paintings, Seth sometimes has red hair and red eyes, to show that he is weird and different. He also has an animal head, and sometimes takes the form of a crocodile, a hippopotamus, or a black pig – all dangerous animals.
In one story, Seth drowned his brother Osiris in the Nile River and cut his body into pieces. Osiris’ son Horus found his uncle Seth and fought him to avenge his father. In the battle, Horus lost his left eye, and Seth lost the ability to have children. (Does this story remind you of the Disney movie “Lion King”, which was also set in Africa? Also compare it to the West African story of Sundiata.)
In ancient Egypt, Osiris was identified with the constellation of stars we know as Orion, and the story may be a way of explaining why Orion appears in the sky and then seems to be pushed aside by other constellations as the earth goes around the sun.
In other Egyptian stories, however, Seth and Horus are sometimes different sides of the same god, and people prayed to them together.
