Experts say loss of 1,500 items reveals lax cataloguing and boosts case for returning objects to countries of origin

Close observers of the antiquities market tend to be a cynical bunch, having witnessed any number of scams, dubious practices and illicit trading. Yet there was a collective expression of shock among them last week when news emerged of the unexplained absence of a reported around 2,000 items from the British Museum’s priceless collection of ancient and historical artefacts, leading to the resignation of director Hartwig Fischer.

“The volume of missing objects is huge,” says Christos Tsirogiannis, a forensic archaeologist who works with Trafficking Culture, which researches global traffic in looted cultural objects. “No experts were expecting this to happen in one of the world’s biggest museums.”
