(Egyptian for “emptiness” and “he who rises up”) was one of the primordial Egyptian gods, a personification of air, one of the Ennead of Heliopolis. In some myths, Shu was the son of Atum and Iusaaset. In other versions, Shu and his sister Tefnut were created by Atum alone, via parthenogenesis. With Tefnut (“moisture”), Shu was the father of Nut and Geb and grandfather of Osiris, Isis, Set, Horus and Nephthys. His great-grandson is Anubis.
