Osiris

Osiris, one of the principal gods of Egypt, the husband of Isis, who was his sister and the father of Horus, who avenged the wrongs he suffered at the hands of the Earth, his mother, in whose womb he was born and in whose womb he was buried; he was the god of all the earth-born, and subject to the like fate.
