The center of his cult was in Lemnos. Hephaestus' symbols are a smith's hammer, an anvil and a pair of tongs, although sometimes he is portrayed holding an axe. Hephaestus is the only Olympian God to have been exiled from Olympus and return. In a Homeric version of Hephaestus' myth, Hera, mortified to have brought forth such grotesque offspring, promptly threw him from Mount Olympus. He fell nine days and nights and landed in the ocean. Hephaestus, being the most unfaltering of the gods, was given Aphrodite's hand in marriage by Zeus in order to prevent conflict over her between the other gods. However, this did not stop her from having secret affairs with other men, be it mortal or god. It was Ares she was attracted to the most, something that Helios told Hephaestus after catching them in an affair.
