Ancient Egypt

Isis was the wife of Osiris. Ra made Osiris the god of the dead. That meant he would dwell forever in the land of the dead. Isis, his wife, would live forever in the land of the living. Isis knew that she would never see her beloved husband again. From then on, once each year Isis travels to the riverbank and cried. That is why the ancient Egyptians believed the Nile River flooded each year. When Isis cries, the Nile will rise! And that was a most important thing. The Legend of Isis and Osiris, Gifts of the Nile
