It’s big, it’s heavy, and it’s beautiful. Dora Ching, the Associate Director of the Tang Center for Asian Art at Princeton University, has created a book that will surely become the volume to have if you are interested in Buddhist art from China or the history of photography. This book presents the art found in the Dunhuang (Mogai) Caves (now often called the Thousand Buddha Grottoes) of western China, which boast more than 500 cave temples, every one of them decorated with sculpture, various images of  the Buddha, a great number of murals and smaller-scale paintings, and some with caches of invaluable illustrated manuscripts.
