It’s one of the most famous natural disasters in history. On August 24, 79 A.D., Mount Vesuvius erupted, sending floods of ash, pumice and other debris onto the city of Pompeii, located at the volcano’s southeastern base in the Campania region of Italy. By the next day, the eruption had buried the city and its terrified inhabitants under nearly 20 feet of debris, where they would remain frozen in layers of ash for the next 1,500 years. Now, a team of French archaeologists working in Pompeii has made a remarkable find: a perfectly preserved pre-Roman tomb dating to the 4th century B.C., when Pompeii was home to the Samnite people.
