Perhaps one of the best know Egyptian deities, Osiris is a member of the Heliopolitan Ennead. He was the first child of Nut and Geb, and born in Upper Egypt, the region which he, and later, his son, would be associated with. Osiris succeeded his father and became king of Egypt, making his sister, Isis, his queen. Osiris brought civilization and agriculture to Egypt, and outlawed cannibalistic practices. It was under his reign that culture first began to appear. Osiris set out on many foreign campaigns to spread the new civil practices he first introduced to Egypt. Upon his return to Egypt, his brother, Set, began to plot against him. The resulting famous tale of fratricide, betrayal, and the ongoing struggle for power between generations is the most recognizable tale we have from ancient Egypt. In short, Osiris is murdered by his brother, dismembered, reassembled, and thus becomes associated with death and becomes the major god in the Hall of Judgment. Osiris also becomes the god of the Underworld, but because of his resurrection, he also becomes associated with regeneration and fertility. Osiris is portrayed as a man clad in white, or in mummiform, with a characteristic atef crown and usually green skin; green being the color that signifies death in ancient Egypt.
