weapon, the thunderbolt, which had been hidden by Gaia. A great war was begun, the Titanomachy, between the new gods, Zeus and his siblings, and the old gods, Cronus and the Titans, for control of the cosmos. In the tenth year of that war, following Gaia's counsel, Zeus released the Hundred-Handers, who joined the war against the Titans, helping Zeus to gain the upper hand. Zeus cast the fury of his thunderbolt at the Titans, defeating them and throwing them into Tartarus. A final threat to Zeus' power was to come in the form of the monster Typhon, son of Gaia and Tartarus. Zeus with his thunderbolt was quickly victorious, and Typhon was also imprisoned in Tartarus. Zeus, by Gaia's advice, was elected king of the gods, and he apportioned various honors among the gods. Zeus then married his first wife Metis, but when he learned that Metis was fated to produce a son which might usurp his rule, by the advice of Gaia and Uranus, Zeus swallowed Metis (while still pregnant with Athena). And so Zeus managed to end the cycle of succession and secure his eternal rule over the cosmos. The genealogies The first gods The world began with the spontaneous generation of four beings: first arose Chaos (Chasm); then came Gaia (Earth), "the ever-sure foundation of all"; "dim" Tartarus, in the depths of the Earth; and Eros (Desire) "fairest among the deathless gods". From Chaos came Erebus (Darkness) and Nyx (Night). And Nyx "from union in love" with Erebus produced Aether (Brightness) and Hemera (Day). From Gaia came Uranus (Sky), the Ourea (Mountains), and Pontus (Sea). Children of Gaia and Uranus Uranus mated with Gaia, and she gave birth to the twelve Titans: Oceanus, Coeus, Crius, Hyperion, Iapetus, Theia, Rhea, Themis, Mnemosyne, Phoebe, Tethys and Cronus; the Cyclopes: Brontes, Steropes and Arges; and the Hecatoncheires ("Hundred-Handers"): Cottus, Briareos, and Gyges. Children of Gaia and Uranus' blood, and Uranus' genitals When Cronus castrated Uranus, from Uranus' blood which splattered onto the earth, came the Erinyes (Furies), the Giants, and the Meliai. Cronus threw the severed genitals into the sea, around which foam developed and transformed into the goddess Aphrodite. Descendants of Nyx Meanwhile, Nyx (Night) alone produced children: Moros (Doom), Ker (Destiny), Thanatos (Death), Hypnos (Sleep), Oneiroi (Dreams), Momus (Blame), Oizys (Pain), Hesperides (Daughters of Night), Moirai (Fates), Keres (Destinies), Nemesis (Retribution), Apate (Deceit), Philotes (Love), Geras (Old
