What is the Roman name for the Greek god Hephaestus?

The Roman name for the Greek god Hephaestus is Vulcan. Hephaestus, known in Greek mythology as the god of fire, metalworking, stone masonry, and the art of sculpture, was highly regarded for his craftsmanship and skill as a blacksmith. The Romans adopted many aspects of Greek mythology, including the pantheon of gods, but often assigned them different names. In this case, Vulcan embodies the same attributes as Hephaestus, representing the fire and forge, and was similarly celebrated in Roman culture, particularly in the context of craftsmanship and volcanic activity.

Vulcan was also associated with destructive fire, including that of volcanoes, establishing a multi-dimensional persona in both mythology and Roman religion. While Neptune (the equivalent of Poseidon) governs the sea, Mars (the god of war) and Pluto (the god of the underworld) pertain to entirely different domains, making it clear that Vulcan is the accurate answer connecting directly to Hephaestus.
