The Titans play a key role in an important part of Greek mythology, the succession myth. It told how the Titan
Cronus, the youngest of the Titans, overthrew
Uranus, and how in turn Zeus, by waging and winning a great ten-year war pitting the new gods against the old gods, called the
Titanomachy ("Titan war"), overthrew Cronus and his fellow Titans, and was eventually established as the final and permanent ruler of the cosmos.
Hesiod and
Cristofano Gherardi, c. 1560 (Sala di Cosimo I,
Palazzo Vecchio) According to the standard version of the succession myth, given in Hesiod's
Theogony, Uranus initially produced eighteen children with Gaia: the twelve Titans, the three
Cyclopes, and the three
Hecatoncheires (Hundred-Handers), but hating them, he hid them away somewhere inside Gaia. Angry and in distress, Gaia fashioned a
sickle made of
adamant and urged her children to punish their father. Only her son Cronus was willing. So Gaia hid Cronus in "ambush", gave him an adamantine sickle, and when Uranus came to lie with Gaia, Cronus reached out and castrated his father. This enabled the Titans to be born and Cronus to assume supreme command of the cosmos, with the Titans as his subordinates. Cronus, having now taken over control of the cosmos from Uranus, wanted to ensure that he maintained control.
Uranus and
Gaia had prophesied to Cronus that one of Cronus' own children would overthrow him, so when Cronus married Rhea, he made sure to swallow each of the children she birthed. This he did with the first five:
Hestia,
Demeter,
Hera,
Hades,
Poseidon (in that order), to Rhea's great sorrow. However, when Rhea was pregnant with Zeus, Rhea begged her parents Gaia and Uranus to help her save Zeus. So they sent Rhea to
Lyctus on Crete to bear Zeus, and Gaia took the newborn Zeus to raise, hiding him deep in a cave beneath Mount Aigaion. Meanwhile, Rhea gave Cronus a huge stone wrapped in baby's clothes which he swallowed thinking that it was another of Rhea's children. Zeus, now grown, forced Cronus (using some unspecified trickery of Gaia) to disgorge his other five children. Zeus then released his uncles the Cyclopes (apparently still imprisoned beneath 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 an
emetic which forced him to disgorge his children that he had swallowed. According to Apollodorus, in the tenth year of the ensuing war, Zeus learned from Gaia, that he would be victorious if he had the Hundred-Handers and the Cyclopes as allies. So Zeus slew their warder
Campe (a detail not found in Hesiod) and released them, and in addition to giving Zeus his thunderbolt (as in Hesiod), the Cyclopes also gave
Poseidon his
trident, and
Hades his
helmet, and "with these weapons the gods overcame the Titans, shut them up in Tartarus, and appointed the Hundred-handers their guards".
Hyginus The Roman mythographer
Hyginus, in his
Fabulae, gives an unusual (and perhaps confused) account of the Titanomachy. According to Hyginus the Titanomachy came about because of a dispute between
Jupiter and
Juno (the Roman equivalents of Zeus and Hera). Juno, Jupiter's jealous wife, was angry at her husband, on account of Jupiter's son
Epaphus by
Io (one of her husband's many lovers). Because of this Juno incited the Titans to rebel against Jupiter and restore
Saturn (Cronus) to the kingship of the gods. Jupiter, with the help of
Minerva (
Athena),
Apollo, and
Diana (
Artemis), put down the rebellion, and hurled the Titans (as in other accounts) down to Tartarus. ==After the Titanomachy==
