Uranus hid the youngest children of Gaia, the one-hundred armed giants (Hecatonchires) and the one-eyed giants, the Cyclopes, in Tartarus so that they would not see the light, rejoicing in this evil doing. This caused pain to Gaia (Tartarus was her bowels) so she created grey flint and shaped a great sickle and gathered together Cronus and his brothers to ask them to obey her. Only Cronus was willing to do the deed, so Gaia gave him the sickle and set him in ambush. Cronus jumped out and lopped off his father's testicles, casting them behind him. From his blood on the Earth came forth the Gigantes, Erinyes and Meliae. From the testicles of Uranus in the sea came forth Aphrodite. For this, Uranus called his sons Titans, meaning "strainers" for they strained and did presumptuously a fearful deed, for which vengeance would come afterwards. After Uranus was deposed, however, Cronus returned the Hecatonchires and Cyclopes to Tartarus.
