Mount Vesuvius is a volcano in the Gulf of Naples, Italy. It is best known for its eruption in in AD 79 that caused the destruction of the Roman cities of Pompeii and Herculaneum. The cities were abandoned and forgotten until a chance discovery in the 18th century. It is the only volcano on the European mainland to have erupted in the last hundred years, although it is currently innactive.
During the start of the Third Servile War, Spartacus and his small rebel force used an abandoned temple at the base of the mountain for training.
Claudius Glaber managed to overwhelm the rebels and drove them to the top of the mountain, planning to starve them towards surrendering.
