Most of the items were found during restoration and refurbishment work in buildings dating from the Mediaeval period, around the time the city was founded (11th-12th centuries).
Finds from the Roman era can be dated between the 1st century BC and the 4th century AD. The oldest is the lid of a sandstone cinerary urn, with an inscription written in Latin and Umbrian alphabet; it dates from between the 2nd and 1st centuries BC. The Statue of Hercules, believed to be a copy of a Greek piece from the 4th century BC, dates from the 1st century BC. Hercules is shown naked, leaning on a gnarled club with his right hand. The ‘leonte’ (the skin of a Nemean lion) on his left arm and the apples of the Hesperides in his left hand, recall two of the twelve labours performed by the hero. The white marble statue was restored, probably in the 18th century, using pieces of Italic marble.
