In Egyptian religion, a goddess of the sky, vault of the heavens, often depicted as a woman arched over the earth god Geb. On five special days preceding the New Year, Nut gave birth successively to the deities Osiris, Horus, Seth, Isis, and Nephthys. These gods, with the exception of Horus, were commonly referred to as the children of Nut. In the Heliopolitan doctrine of the Ennead she was considered the daughter of Shu and sister-wife of Geb.
