The exhibition, which includes dozens of works of art, serves as a sobering reminder of how widespread and damaging looting in Italy has been. One display points out that when an item is looted, the problem isn’t just that it risks disappearing into the hands of a private collector, winding up abroad or being damaged. (One popular way to transport looted vases, for example, is to deliberately break them into shards and reconstruct them later, as fragments are easier to hide and move.) The irreversible loss is the item’s context. Without knowing where the piece was found, at what depth, or near which other objects, it is all but impossible to fully reconstruct the piece’s history, use and meaning.
