ISIS have marred cultural treasures in Iraq and Syria, taking sledgehammers and drills to statues at the Mosul Museum and delivering numerous blows to the ancient site of Palmyra. A number of projects that engage with existing and developing technologies have emerged in recent years to trace the histories and even reconstruct destroyed objects. While many of these respond to cultural loss from human conflict, still others are concerned with ever present sources of erasure, from looting and illicit dealing to weather and the passing of time. The Missing: Rebuildng the Past examines how artists and scholars use creative means to protest preventable loss. Co-curated by Erin Thompson and Jessica Carlisle, the exhibition premiered at the Anya and Andrew Shiva Gallery at John Jay College of Criminal Justice, New York City in February 2016. Its London edition will coincide with the unveiling of a life-sized replica of the Palmyra Arch in both Trafalgar Square on 19th April.
