In 79 AD, the eruption of a nearby volcano, Mount Vesuvius, buried Pompeii in millions of tonnes of ash and debris. Now, archaeologists are working to uncover the dark side of this idyllic Roman city by finding the room of an enslaved person.

New discoveries uncover how the Romans ruled the seas for four centuries. Archeologists dive a small cargo ship wrecked off Sukosan, Croatia, from the 1st Century CE; test two replica small river patrol boats in Gunzenhausen, Germany, from the 2nd and 4th Centuries CE; and explore the Roman harbor at Puteoli, Italy, the largest transit port for Rome at the beginning of the 1st Century CE.
