Tanis, Egypt, circa 1939. On the brink of World War II, an excavation team led by French archaeologist Pierre Montet unearthed an intact royal burial chamber containing treasures that rival the riches found in Tutankhamun’s tomb almost two decades before. But while the Tut discovery created an international sensation, the opening of the tomb in Tanis made barely a ripple in a world focused on impending war.

In 2009, archaeologists discovered an underwater graveyard of five Roman shipwrecks off the coast of Ventotene, a small Italian island with a notorious past. It was one of the biggest archaeological finds in recent history. The vessels’ well-preserved cargo indicates that these ships did not break up on the island’s rocks, but instead sank to the seabed intact and upright. They were laden with exotic goods including wine, olive oil, and the ancient delicacy garum; a condiment highly prized among ancient Romans. These sunken treasures are providing researchers with insight into the wreck, how the Romans lived, and Ventotene’s intriguing past.
