Osiris - God of the Dead
dressed in white with crook and flail and white crown

Crrok and flail Osiris is shown as a man with a beard wearing white mummy wrappings. His crown is the white crown of Upper Egypt surrounded by red feathers. His skin is green to represent vegetation. He holds the symbols of supreme power, the flail and crook. The crook is used by shepherds to catch their sheep. The flail is used in threshing, to separate the grains from the outer husks. Osiris was the God of the Dead. You would expect that such a god would be gloomy or even evil, but the Egyptians thought about death a lot. They mummified their dead and buried them with their belongings so they could enjoy themselves in the afterlife.

Osiris This story begins on Nut and Geb's page. Osiris ruled over the Egyptians and taught them farming. His brother Seth had always hated him, and wanted to kill him. Seth made a beautiful box, like a coffin, made to the exact measurements of Osiris. Then Seth invited Osiris and other people to a great feast. When everyone had finished eating, Seth displayed the box, and said that he'd give it to anyone who fitted inside. Everyone tried, but only Osiris fitted. While he was still inside, Seth and his friends quickly slammed on the lid and threw the box in the Nile river. But what happened next?
