LIANGZHU CULTURE, CIRCA 3300-2300 BC

Compare with an example, similar to the present lot, with only one register of masks and linear designs of Liangzhu jade cong, in the Zhejiang Provincial Institute of Cultural Relics and Archaeology and illustrated in Liangzhu wenhua yuqi, Hong Kong, 1989, p. 30, no. 39. Compare also another similarly carved Liangzhu cong of shorter height and wider width from the British Museum, which is included in Jessica Rawson, Chinese Jade-from the Neolithic to the Qing, London, 1995, pl. 3:2, p. 126.
