Epimenides (7th or 6th century BC) seemingly knew a different version of the story, in which Typhon enters Zeus' palace while Zeus is asleep, but Zeus awakes and kills Typhon with a thunderbolt. Pindar apparently knew of a tradition which had the gods, in order to escape from Typhon, transform themselves into animals, and flee to Egypt. Pindar calls Typhon the "enemy of the gods", and says that he was defeated by Zeus' thunderbolt. In one poem Pindar has Typhon being held prisoner by Zeus under Etna, and in another says that Typhon "lies in dread Tartarus", stretched out underground between Mount Etna and Cumae. In Aeschylus' "Prometheus Bound", a "hissing" Typhon, his eyes flashing, "withstood all the gods", but "the unsleeping bolt of Zeus" struck him, and "he was burnt to ashes and his strength blasted from him by the lightning bolt."
