Vulcan

Vulcan is the Roman god fire of volcanoes, deserts, metalworking, and the forge.

Overview
Vulcan was often conflated with the Greek god Hephaestus, and was such seen as the son of Jupiter and Juno, who was sometimes said to be thrown down Mount Olympus by his mother for being a cripple.

He would eventually join the Roman gods again, and he would be married to Venus, the goddess of love and beauty. Despite being married, Venus would often cheat on Vulcan, notably with Mars, the god of war and agriculture.

He also was the father of Cacus, a fire-breathing giant who was killed by the demigod Hercules, who was Vulcan's half brother from Jupiter's side.

His festival was called Vulcanalia and was the annual festival held August 23, and received a sacrifice in the form a red bull and calf. This made him one of the gods who received a bull-sacrifice, alongside Jupiter, Mars, Neptune and Apollo.

Cultural comparisons
Like most Roman gods, Vulcan was equated with a Greek god, in this case Hephaestus, as well as several other deities, such as the Etruscan god Sethlans, the Slavic god Svarog and the Egyptian god Ptah.
