Hephaestus is the Greek god of artisans, blacksmiths, carpenters, craftsmen, fire, metallurgy, metalworking, sculpture, and volcanoes. In Greek mythology, Hephaestus was the son of Hera, either on her own or by her husband Zeus. He was cast off Mount Olympus by his mother Hera because of his lameness, the result of a congenital impairment; or in another account, by Zeus for protecting Hera from his advances.

As a smithing god, Hephaestus created all the weapons of the gods in Olympus. He served as the blacksmith of the gods, and was worshipped in the manufacturing and industrial centres of Greece, particularly Athens. The cult of Hephaestus was based in Lemnos. Hephaestus's symbols are a smith's hammer, anvil, and a pair of tongs. In Rome, he was equated with Vulcan.
