Osiris was not only the redeemer and 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.
Osiris (Greek language, also Usiris; the Egyptian language name is variously transliterated Asar, Aser, Ausar, Ausir, Wesir, or Ausare) was the Egyptian god of life, death, and fertility.
Osiris is one of the oldest gods for whom records have been found; one of the oldest known attestations of his name is on the Palermo Stone of around 2500 BC. He was widely worshipped until the suppression of paganism by the early Catholic church under Theodosius I[1]. The information we have on the myths of Osiris is derived from allusions contained in the Pyramid Texts (ca. 2400 BC), later New Kingdom source documents such as the Shabaka Stone and the Contending of Horus and Seth, and much later, in narrative style from the writings of Greek authors including Plutarch[2] and Diodorus Siculus.[3]
