Shu is an ancient Egyptian deity, one of the earliest known gods in the Egyptian pantheon. He is typically depicted as a man wearing a headdress with two large ostrich feathers, often accompanied by his sister and consort, Tefnut, who is associated with moisture. Shu is the god of air and the dryness of the air, which distinguishes him from Tefnut, who represents moisture. Together, they are the children of Atum, the creator god, and are considered the parents of Nut (the sky) and Geb (the earth). The name "Shu" translates to שו in Hebrew, though it is not a commonly used term in modern Hebrew. In ancient Egyptian, his name is transliterated as Šw. Shu's role in Egyptian mythology is crucial as he represents the separation of the sky (Nut) from the earth (Geb), maintaining the order of the cosmos. This separation is a fundamental aspect of Egyptian cosmology, illustrating the balance and harmony that Shu embodies. His worship was widespread, and he was often invoked in rituals to ensure the stability and order of the universe.
