Volcanology that Hephaestus, the god of fire, sat below the volcano Etna, forging the weapons of Zeus. The Greek word used to describe volcanoes was "etna", or "hiera", after Heracles, the son of Zeus. The Roman poet Virgil, in interpreting the Greek mythos, held that the giant Enceladus was buried beneath Etna by the goddess Athena as punishment for rebellion against the gods; the mountain's rumblings were his tormented cries, the flames his breath and the tremors his railing against the bars of his prison. Enceladus' brother Mimas was buried beneath Vesuvius by Hephaestus, and the blood of other defeated giants
Hephaestus containing his workshop with anvil and twenty bellows that worked at his bidding. Hephaestus crafted much of the magnificent equipment of the gods, and almost any finely wrought metalwork imbued with powers that appears in Greek myth is said to have been forged by Hephaestus. He designed Hermes' winged helmet and sandals, the Aegis breastplate, Aphrodite's famed girdle, Agamemnon's staff of office, Achilles' armor, Heracles' bronze clappers, Helios's chariot, the shoulder of Pelops, and Eros's bow and arrows. In later accounts, Hephaestus worked with the help of the chthonic Cyclopes—among them his assistants in the forge, Brontes, Steropes and Pyracmon.
