Hephaestus is the son of Zeus and Hera. Sometimes it is said that Hera alone produced him and that he has no father. Hephaestus is the only god to be physically ugly and is also lame. Accounts as to how he became lame vary. Some say that Hera, upset by having an ugly child, flung him from Mount Olympus into the sea, breaking his legs. Others that he took Hera's side in an argument with Zeus and that Zeus flung him off Mount Olympus. He is the god of fire and the forge. He is the smith and armourer of the gods. He uses a volcano as his forge. He is the patron god of both smiths and weavers. He is kind and peace loving. His wife is Aphrodite. Sometimes his wife is identified as Aglaia.
