The bronze heads to be seen at Vienna's Belvedere Palace until a few weeks ago represented the 12 heads of the 18th cent. zodiac circle of animals at Yuanmingyuan - the Palace of Calm Seas - in Beijing. Twelve figures adorned the water-clock fountain in front of the palace until 1860 when the site was destroyed by British and French troops during the Second Opium War and the heads were looted. Seven of the heads have since found their way back to China. Four recovered heads were in possession of a world famous fashion designer in Paris according to information available at the Belvedere. Five heads are still missing. May they return safely home. The artist is Ai Weiwei.
