Set or Seth (both: sĕt or sāt) [key], in Egyptian religion, god of evil. Set was a sun god of predynastic Egypt, but he gradually degenerated from being a beneficent deity into being a god of evil and darkness. In a widespread Egyptian myth he murdered his brother Osiris and was in turn defeated by Horus, the son of Osiris. The Greeks identified Set with Typhon.
