After a major eruption of Mount Vesuvius in 1858, local farmers began hearing terrifying screams every night that prevented them from sleeping. Unable to find the source, they called upon a witch named Mattavona who lived on Vesuvius's slopes. After reciting incantations, the screams stopped, allowing the people to sleep peacefully once more. The legend of the witch of Vesuvius was inspired by depictions in Mickey Mouse comics and an animated film about a young storyteller in 18th century Naples.
