In Egyptian mythology, Satis (also spelt Satjit, Sates, and Sati) was the deification of the floods of the Nile River, and originated in the region around Aswan, the southern edge of Egypt. Her name means ejaculation (i.e. that which is ejected out), as many Egyptians believed that the annual flooding of the Nile was due to the masturbation of Atum.
