In ancient Egypt, Osiris was a very popular god. He became increasingly important and became one of the greatest and most important gods in Egypt. His death is described in one of the most famous myths of Ancient Egypt: the Osiris myth. Osiris was the god of the dead and eternal life in the hereafter. Osiris was also often identified with the god Wenen-nefer, "who is constantly youthful," which fits with a dying and reviving god. Like a phoenix, he is a clear example of resurrection after a period of symbolic death or sleep.
