It’s time for the Elgin Marbles to go home. For Britain’s sake. “The marbles in the British Museum are performers, trained as actors in a ceremony. But this is not the Panathenaic Procession. It is a Great British ceremony, about an imperial splendour which thought of itself as universal rather than merely national. In the Duveen Gallery, within the British Museum, these figures no longer deliver Athens any more than the bagpipers who tramp round banquets at Windsor Castle deliver Scotland. They are guests from Greece who became so well known during the 19th century that they were adopted into the family.”
