Volcanology has a background of superstition and mythology

In Roman mythology, Vulcan was the god of fire, the blacksmith of the gods.

• Poets identified Vulcan's workshop with various active volcanoes in the belief that the "smoking" mountain was the chimney of Vulcan's forge.
• In ancient mythology, Vulcan's forge was located on the island of Vulcano, one of the Lipari islands off the coast of Sicily.
• Based on this relationship, the name "volcano" was applied to all mountains which give off "smoke and fire".
