Osiris (Usire)
Egyptian god of the underworld and of vegetation. Son of Nut and Geb and brother of Nephthys, Set and brother-husband to Isis. His birthplace was said to be Rosetau in the necropolis west of Memphis. Osiris was depicted in human form wrapped up as a mummy, holding the crook and flail. He was often depicted with green skin, alluding to his role as a god of vegetation. He wore a crown known as the 'atef,' composed of the tall conical whittle crown of Upper Egypt with red plumes on each side. Osiris had many cult centers, but the most important were at Abydos (Ibdju) in Upper Egypt, where the god's legend was reenacted in an annual festival and at Busirs (Djedu) in the Nile delta.
