Vulcan is the god of beneficial and hindering fire, including the fire of volcanoes in ancient Roman religion and Roman Neopaganism. He is also called Mulciber ("smelter") in Roman mythology and Sethlans in Etruscan mythology. He was worshipped at an annual festival on August 23 known as the Volcanalia. The god belongs to the most ancient stage of Roman religion: Varro citing the Annales Maximi, recalls that king Titus Tatius had dedicated altars to a series of deities among which Vulcan is mentioned. Vulcan was identified with the Greek god of fire and smithery, Hephaestus.
