Jade. China, Han Dynasty, 2nd century BC 穀紋玉璧 - 漢代, 公元前2世紀 This and the following lot are examples of jade discs that were crafted during the Han dynasty and decorated with patterns derived from the previous Eastern Zhou period. Both sides of this very beautiful shiny disc are covered with a delicate motif of differently orientated incised scrolls framed by two narrow, plain bands that define the borders around the central perforation and the perimeter. The large hole is slightly off centre, thus the body of the disc shows some small variations in width. The disc is fairly uniform in thickness, except for a very noticeable section where the flat surface slopes down considerably towards the outer edge: here the jade is whitish and rough on both sides. The disc appears almost black in colour but when held to the light one can perceive that it is actually a beautiful shade of lighter green, with spots, lines and diffused striations of black that indicate the high content of iron. The many patches of white and light brown add a patina to the otherwise shiny surface of the jade. There are also some noticeable chips around the external border. From excavations, a similar disc was found in 1974 in tomb no.1 of the Zhongshan state royal cemetery at Nanqiji, in Pingshan county, Hebei province: it is published in Yang Boda (ed.), Zhongguo yuqi quanji: 3, Chunqiu Zhanguo中国玉器全集/3/春秋战国 (Chinese Jades: 3, Spring and Autumn and Warring States), Hebei 1993, no.212.
