It's good to be the king - or the emperor. Pleasure, power, and extreme wealth often come with the job. The exploits of Caligula are legendary, and he even took those activities to the water when he built two luxurious party ships and parked them on Lake Nemi near Rome. The Lake Nemi ships were intentionally sunk during the second half of the first century and were finally recovered during the 1930s. Artifacts from the ships went to a museum in Italy but many items were destroyed in World War II. Recently, a mosaic from one of the ships turned up in New York City, proving all is not lost for Caligula's sex ships, but it does raise interesting questions as to how it got there.
