Artist Gerry Judah has installed a pair of otherworldly sculptures in the nave in St Paul’s Cathedral in London, commemorating the 100th anniversary of the beginning of the First World War. Painted white, the giant crosses evoke the war graves of northern France but also the more rudimentary markers that are used to indicate makeshift graves all over the world. The strange appearance of the crosses is, on closer inspection, due to each carrying a series of recreations of bombed-out buildings and structures across its beams. “In the damaged buildings there is a further element, too, of revelation, for destruction is a kind of perverse archaeology,” says Judah. “Bombs expose the private, the personal, the intimate; the skin of a building ripped away to show lived lives ended in a single blast.” The Calcutta-born artist, who has lived in London since the early 1960s, had previously worked as a scenic artist for the theatre. Since focusing on the creation of public art, Judah has made pieces for numerous institutions such as the Holocaust Exhibition at the Imperial War Museum in London. Much of his recent three-dimensional work has focused on conflicts in Eastern Europe and the Middle East.
