Hephaestus (Vulcan) was the god of fire and the protector of the metal workers. He was lame and deformed, but very powerful. His wife was Aphrodite. He made the golden throne of Zeus.
Hephaestus was married
to Aphrodite, but Aphrodite was not very faithful to him. So Hephaestus
attempted to rape Athena to aggravate Aphrodite. This resulted
in the birth of Erichthonios.
