the earth, along with the Hundred-Handers, where Uranus had originally confined them) who then provide Zeus with his great weapon, the thunderbolt, which had been hidden by Gaia. A great war was begun, the Titanomachy, for control of the cosmos. The Titans fought from Mount Othrys, while the Olympians fought from Mount Olympus. In the tenth year of that great 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, with the Hundred-Handers as their guards. Homer Only brief references to the Titans and the succession myth are found in Homer. In the Iliad, Homer tells us that "the gods ... that are called Titans" reside in Tartarus. Specifically, Homer says that "Iapetus and Cronos ... have joy neither in the rays of Helios Hyperion [the Sun] nor in any breeze, but deep Tartarus is round about them", and further, that Zeus "thrust Cronos down to dwell beneath earth and the unresting sea." Other early sources Brief mentions of the Titanomachy and the imprisonment of the Titans in Tartarus also occur in the Homeric Hymn to Apollo and Aeschylus' Prometheus Bound. In the Hymn, Hera, angry at Zeus, calls upon the "Titan gods who dwell beneath the earth about great Tartarus, and from whom are sprung both gods and men". In Prometheus Bound, Prometheus (the son of the Titan Iapetus) refers to the Titanomachy, and his part in it: Apollodorus The mythographer Apollodorus, gives a similar account of the succession myth to Hesiod's, but with a few significant differences. According to Apollodorus, there were thirteen original Titans, adding the Titaness Dione to Hesiod's list. The Titans (instead of being Uranus' firstborn as in Hesiod) were born after the three Hundred-Handers and the three Cyclopes, and while Uranus imprisoned these first six of his offspring, he apparently left the Titans free. Not just Cronus, but all the Titans, except Oceanus, attacked Uranus. After Cronus castrated Uranus, the Titans freed the Hundred-Handers and Cyclopes (unlike in Hesiod, where they apparently remained imprisoned), and made Cronus their sovereign, who then reimprisoned the Hundred-Handers and Cyclopes in Tartarus. Although Hesiod does not say how Zeus was eventually able to free his siblings, according to Apollodorus, Zeus was aided by Oceanus' daughter Metis, who gave Cronus
