Primordial Egyptian god of the air and supporter of the sky. In the Heliopolitan creation myth, Shu was, with his sister Tefnut, one of the first deities created by the sun god Atum, either from his semen or from the mucus of his nostrils. Tefnut then became his consort, giving birth to the sky goddess Nut and the earth god Geb. Shu separated Geb and Nut (heaven and earth) by interposing himself between them. Depicted in human form wearing an ostrich feather, the hieroglyph for his name, with his arms raised to support the goddess Nut above the supine form of Geb.
