Cosmogony and Castration of Ouranós
Khaos was the first to come to be, followed by Gaia, Tartaros and Eros. From Khaos came forth Erebus and Nyx, and from Nyx and Erebus came Aether and Hemera. From Gaia came Ouranós, the Ourea and Pontus.

Gaia then lay with Ouranos and bore Oceanus, Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe and Tethys. After them Cronos was born. After that she mated with Ouranos once again, and bore the Cyclopes; Brontes, Steropes and Arges, who made thunder for Zeus. She also had the Hecatonchires; Kottos, Briareos, and Gyges. Ouranós was disgusted with them and hid them away in the Earth. She asked the Titans to punish their father. Cronos volunteered and castrated him with the sickle his mother had given him.
