Osiris was the husband of Isis and the father of Horus. Osiris resided in the underworld as the lord of the dead, as after being killed by Set, even though he was a god, he could no longer dwell in the land of the living. After Osiris was killed, Isis resurrected him with the Ritual of Life, which was later given to the Egyptians so that they could give eternal life to all their dead.
Osiris was not only a merciful judge of the dead in the afterlife, but also the underworld agency that granted all life, including sprouting vegetation and the fertile flooding of the Nile River. He is described as the "Lord of love", "He Who is Permanently Benign and Youthful" and the "Lord of Silence".
Osiris was widely worshiped as Lord of the Dead until the suppression of the Egyptian religion during the Christian era.
