In the versions of the battle given by Hesiod, Aeschylus and Pindar, Zeus' defeat of Typhon is straightforward, however a more involved version of the battle is given by Apollodorus. No early source gives any reason for the conflict, but Apollodorus' account seemingly implies that Typhon had been produced by Gaia to avenge the destruction, by Zeus and the other gods, of the Giants, a previous generation of offspring of Gaia. According to Apollodorus, Typhon, "hurling kindled rocks", attacked the gods, "with hissings and shouts, spouting a great jet of fire from his mouth." Seeing this, the gods transformed into animals and fled to Egypt (as in Pindar and Nicander). However "Zeus pelted Typhon at a distance with thunderbolts, and at close quarters struck him down with an adamantine sickle" Wounded, Typhon fled to the Syrian Mount Kasios, where Zeus "grappled" with him. But Typhon, twining his snaky coils around Zeus, was able to wrest away the sickle and cut the sinews from Zeus' hands and feet. Typhon carried the disabled Zeus across the sea to the Corycian cave in Cilicia where he set the she-serpent Delphyne to guard over Zeus and his severed sinews, which Typhon had hidden in a bearskin. But Hermes and Aegipan (possibly another name for Pan) stole the sinews and gave them back to Zeus. His strength restored, Zeus chased Typhon to mount Nysa, where the Moirai tricked Typhon into eating "ephemeral fruits" which weakened him. Typhon then fled to Thrace, where he threw mountains at Zeus, which were turned back on him by Zeus' thunderbolts, and the mountain where Typhon stood, being drenched with Typhon's blood, became known as Mount Haemus (Bloody Mountain). Typhon then fled to Sicily, where Zeus threw Mount Etna on top of Typhon burying him, and so finally defeated him.
