Osiris and Isis
Osiris was the son of Re who married Isis and became a sole ruler of Egypt after Re. Everyone loved him, except his brother Set. Set tricked Osiris and killed him, leaving poor Isis devastated. However, she managed to put his body back together with magic and embalmed and buried him.
The embalming Isis has used on Osiris’ body is the reason the Egyptians embalmed their dead, so that their souls would return to the earth when Osiris’ son Horus avenges his father.
