Art treasures should be accessible to the greatest number of people and to scholars, and in practice this means retaining them in the great museums of the world. Returning treasures to their original context is impossible, too much has changed physically and culturally over the centuries for them to speak more clearly in their country of origin than they do in museums, where they can be compared to large assemblies of objects from a wide variety of cultures. In any case, perfect laser-cut copies could be placed on the Parthenon and in other original locations, if it were so desired.
