In Egyptian mythology, Isis is the wife of Osiris and mother of Horus.
Isis belonged to the Heliopolitan Ennead, the family of gods descended from the creator deity Atum or Ra. She was the sister of Osiris, Set, and Nephthys, and became Osiris’s queen. After Set murdered Osiris and, in some versions, scattered his body, Isis searched for and restored him with the help of Nephthys and other gods.
Their union produced Horus, who was born after Isis conceived him through magical means following Osiris’s death. She hid and protected the infant Horus in the Nile Delta while he grew strong enough to challenge Set and claim his father’s kingship. This made Isis an enduring symbol of motherhood, healing, magic, and loyal protection.
A common mix-up is Hathor, who was associated with motherhood and was connected with Horus in other traditions. Isis’s defining family role in the Osiris myth, however, is specifically Osiris’s wife and Horus’s mother.
