During World War II, a German military captain acquired a stolen erotic mosaic while stationed in Italy. The ancient artwork came from in or around Pompeii, the city buried by Mount Vesuvius’ eruption in 79 C.

The mosaic shows a pair of lovers who are partially undressed. The tile may have been in a bedroom floor, Pompeii officials said.

The mosaic, which depicts a couple in an intimate bedroom scene, is among thousands of artifacts stolen from the ancient Roman city.
