Book excerpt: This classic guide to Chinese jade is of great interest to art collectors and casual readers alike. First published in 1936 and since then a collector's item of increasing rarity, Chinese Jade Throughout the Ages comprises a review of the characteristics, decorations, folklore, and symbolism of this esteemed mineral that has always held a proud place among gems of the world. The book presents a full descriptive account of the significance and meaning of the carvings produced in this prize stone by Chinese craftsmen from the earliest times, through the Chou and succeeding dynasties, down to the twentieth century. The text is illustrated with a magnificent series of more than 350 reproductions in color, black and white, and line drawings of choice pieces selected from the chief Asian, European, and American collections. In addition the Chinese art history book explains no only the wealth of symbolic designs used in the decoration of jade but also a large number of the marks and devices by which collectors identify the origin and the date of valued pieces.
