Hephaestus is the Greek god of artisans, blacksmiths, carpenters, craftsmen, fire, metallurgy, metalworking, sculpture and volcanoes. Hephaestus's Roman counterpart is Vulcan. In Greek mythology, Hephaestus was either the son of Zeus and Hera or he was Hera's parthenogenous child. 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.

Zeus is the sky and thunder god in ancient Greek religion and mythology, who rules as king of the gods on Mount Olympus. His name is cognate with the first syllable of his Roman equivalent Jupiter.
