- "The "Dancing Feet" spell has its origins in ancient Italy, but is best remembered for its improper usage by Warlock Zaccaria Innocenti who is credited with conjuring a 'dance' within Mt. Vesuvius in 79 AD."
- —How Mt. Vesuvius erupted
Mount Vesuvius is a volcano in the province of Naples in Italy. In 79 AD, Zaccaria Innocenti made inappropriate use of the Dancing Feet Spell spell, "conjuring a 'dance'" within the volcano that resulted in its eruption. This disaster destroyed the Roman cities of Pompeii and Herculaneum, killing at least 1500 people, but made Innocenti's improper usage of the spell legendary.
