In 1956, an exhibition of masterpieces of Chinese art took place in the museum of Asian art in Paris, the Musée Cernuschi. It soon emerged that these pictures were, in fact, forgeries. In this case, the sensitive issue was that the forger was none other than the most famous Chinese painter of the 20th century, Chang Dai-chien, whose works were being exhibited simultaneously at the Musée d'Art Moderne. He was considered the Pablo Picasso of China. And his meeting with Picasso that same year was celebrated as a summit between the masters of Western and Eastern art. Once it became known that the old masterpieces were his forgeries, the Western world regarded him as a mere fraud. Yet for Chang himself, they were anything but forgeries. In any case, most of these old pictures were no mere copies, but rather replicas of lost paintings that were known only from written descriptions.
