Elegantly worked, this charming ram is indicative of Song dynasty jade carving styles. Compare Song dynasty jade deer carved in a similar fashion, such as two illustrated in Yang Boda, ed., Zhongguo yuqi quanji [The Complete Compilation of Chinese Jades], vol. 2, Shijiazhuang, 2005, pls 122 & 123; the first with a very similarly shaped face to the present carving, the second with a body like the present. See also another from the Palace Museum, Beijing, illustrated in The Complete Collection of Treasures of the Palace Museum: Jadeware II, vol. 41, Hong Kong, 1995, pl. 54.
