Osiris was the god of fertility, agriculture, the afterlife, the dead, resurrection, life, and vegetation in ancient Egyptian religion. He was classically depicted with a pharaoh's beard, partially mummy-wrapped at the legs, wearing a distinctive atef crown and holding a symbolic crook and flail. He was one of the first to be associated with the mummy wrap. When his brother Set cut him to pieces after killing him, Osiris's sister-wife, Isis, with her sister Nephthys, searched Egypt to find each part of him. She collected all but one – Osiris's genitalia. She then wrapped his body up, enabling him to return to life. Osiris was widely worshipped until the decline of ancient Egyptian religion.
