In Egyptian mythology, Tefnut is a goddess of water and fertility, indeed her name means moist waters (i.e. rain). She was created by Atum (a solar god, as were Ra, Horakty, and Khepri) from the semen which resulted from his primordial act of masturbation or autofellatio (Heliopolitan version of the Myth), or from his mucus, a mythology that may be related to the alternative translation of her name - spat waters. Another version (the Memphite version of the myth) states that Atum sneezed once and Tefnut's brother Shu was born, and when he coughed to clear his throat Tefnut was born.
