Hephaestus

Hephaestus is the lame Greek god of fire and craftsmen, and was the blacksmith of the gods, creating stuff for them such as weapons and armour in his forge in the middle of a volcano.

He is the son of Zeus and Hera, (some say just Hera), but when Hera saw the ugly baby she threw him down Mt. Olympus. To get her back he made her a magical chair, which when she sat on it, did not allow her to leave it. The other gods begged him to release her, but he would not. Finally, Dionysus was sent down and intoxicated him with his wine. He brought him back up to Olympus on the back of a donkey.

He is married to Aphrodite the goddess of love, however, she is having an affair with Ares, the god of war. He once caught them in bed with an unbreakable net so small it was invisible and dragged them up to mount Olympus for all the gods to see. The gods laughed at the sight of the naked lovers, and Poseidon persuaded Hephaestus to release them.

His Roman counterpart is Vulcan.
