Osirus is the eldest son of Geb and Nut. He is a god of death
and rebirth. On the one hand, he is the Lord of the Underworld,
where he sits and passes judgment on the souls of the dead.
On the other hand, he is responsible for the periodic flooding
of the Nile River, and therefore, the fertility of the land.
He is typically depicted as a green-faced mummy wearing the
atef crown and carrying the crook and flail, all symbols of
a ruler. His brother Set is his enemy. His sister Isis is
his wife, and they have a child, Horus the Younger, who was
conceived magically after Osirus's death.
