Osiris was the Egyptian god of vegetation and civilization. He was one of the children of Geb and Nut, and married to his sister Isis. Osiris represented the male productive force in nature.

Osiris was murdered by his evil brother Seth, who also tore his body to pieces and scattered them. Isis, however, found and enbalmed his scattered remains with help of the god Anubis. Her powerful charms resurrected Osiris. Their son Horus then killed Seth in revenge and became the king of Egypt.

Osiris became the ruler of the dead and the god of the underworld after his death. Even though he lived in the underworld beyond the western horizon, he was also regarded as the source of renewed life through his son Horus.
