There is a roaming display of artwork from the caves of Dunhuang on display at the Seattle Art Museum. The exhibit contains Buddhist artwork and photographs of the caves of Dunhuang, an ancient and strategic location on the Silk Road. (The Silk Road is a network of trade routes that linked the Roman Empire with China for the trade of silk, spices and other commodities such as cotton and jade). A photojournalist called James C.M. Lo, and his wife Lucy, made several arduous journeys to the caves in 1943 during World War II, to systematically photograph the interiors and exteriors of the caves, and to draw attention to their historical significance.
