Hephaestus had his own palace on Olympus, 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' armour, Diomedes' cuirass, Heracles' bronze clappers, Helios' chariot, the shoulder of Pelops, and Eros's bow and arrows. In later accounts, Hephaestus worked with the help of the Cyclopes—among them his assistants in the forge, Brontes, Steropes and Arges.
