Jade Cong

An important burial jade, carved with faces

A group of Neolithic peoples known today as the Liangzhu culture lived in the Jiangsu province of China from about 2500 BC. Their jades, ceramics and stone tools were highly sophisticated.

The Liangzhu people used two distinct types of ritual jade objects: a disc, later known as a bi, and a tube, later known as a cong, of square cross-section, pierced with a circular hole. They clearly had great significance, but despite the many theories the meaning and purpose of bi and cong remain a mystery. They were buried in large numbers: one tomb had twenty-five bi and thirty-three cong.

The corners of most cong are decorated with faces, indicated by eyes and parallel bars. This design is an abbreviated form of a complex figure with a monster face.

Cong were extremely difficult and time-consuming to produce, as jade cannot be split like other stones; it must be worked with a hard abrasive sand. This one is exceptionally long and may have been particularly important in its time.
