OSIRIS, the god of the Underworld

OSIRIS (Asar, Aser, Ausar, Ausir, Wesir, Usir, Usire or Ausare) was an Egyptian god, usually called the god of the Afterlife, underworld or dead.

Osiris is one of the oldest gods for whom records have been found. He was widely worshiped until the suppression of the Egyptian religion during the Christian era.

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. The Kings of Egypt were associated with Osiris in death - as Osiris rose from the dead they would, in union with him, inherit eternal life through a process of imitative magic. By the New Kingdom all people, not just pharaohs, were believed to be associated with Osiris at death if they incurred the costs of the assimilation rituals.

Osiris was at times considered the oldest son of the Earth god, Geb, and the sky goddess, Nut as well as being brother and husband of Isis, with Horus being considered his posthumously begotten son. He was later associated with the name Khenti-Amentiu, which means 'Foremost of the Westerners' a reference to his kingship in the land of the dead.
