Lurking beneath the blue waters of Lake Nemi lay the titans of Roman naval engineering--the Nemi Ships. These titanic luxury liners of the ancient world held inventions lost for thousands of years. But why were they built? Were they Caligula's notorious floating pleasure palaces--rife with excess and debauchery? Flagships of a giant sea force? It took the obsession of Mussolini with all things Roman to finally prise the two huge wrecks from the depths of Lake Nemi near Rome. Using an ancient Roman waterway, he drained the lake and rescued the ships, an accomplishment captured on film that we access to illustrate this astounding story. Sophisticated ancient technology was discovered in the boats that transformed the understanding of Roman engineering overnight--the Nemi ships were a breathtaking find. Yet by 1944, the adventure had turned sour and the retreating German Army torched the boats. We reveal the mysteries of the Nemi Ships and the ancient technology that made them possible.
