Mythological Tales The creation of the world was instigated by the sun-god creating himself in the beginning. When this first step had been completed he produced two other gods, Shu, the air, and Tefenet, humidity, by masturbation. These two in turn united to create Geb, the earth, and Nut, the sky. Nut arched her back over Geb and, in the most obvious fashion, they became the parents of Osiris, Isis, Seth and Nephthys. With the later addition of Horus, son of Isis and Osiris, nine gods had now been created in the world: the Ennead. Other gods arrived and the scene was set for the play of which the very human characteristics of the gods were the origin.
