Discovered among the ruins of the Villa of the Pisones, not far away from Punta Epitaffio, this lead water pipeline allowed for identifying the owners of the entire complex: the inscription on the artefact “L. Pisoni” allows us, in fact, to identify the submerged remains of walls and buildings of a gigantic villa owned by the Pisones family; following an unsuccessful conspiracy against the emperor Nero, the villa became part of the imperial possessions. For a place such as the Gulf of Naples, plenty of seaside villas owned by the most important families of the ancient Rome, a proof so certain as this inscription remains a precious rarity.
