BERLIN (AP).- An American university returned a 15th century painting to a Berlin museum on Monday, more than six decades after the valuable piece was stolen in the chaotic aftermath of World War. The Flagellation of Christ was one of more than a dozen paintings that disappeared from Berlin’s Jagdschloss Grunewald museum during the summer of 1945, looted by British and Russian soldiers. The painting, which originally formed a wing of an altarpiece, was later sold and ended up in the Indiana University Museum of Bloomington. “One of the many tragedies associated with World War II was the loss of countless works of art that were stolen, confiscated, looted, pillaged or destroyed,” Michael McRobbie, the president of Indiana University, said during a handover ceremony at the German capital’s Charlottenburg Palace.
