Jade Cong
Ancient China includes the Neolithic period (10,000 -2,000 B.C.E.), the Shang dynasty (c. 1500-1050 B.C.E.) and the Zhou dynasty (1050-221 B.C.E.). Each age was distinct, but common to each period were grand burials for the elite from which a wealth of objects have been excavated.
The Neolithic Period, defined as the age before the use of metal, witnessed a transition from a nomadic existence to one of settled farming. People made different pottery and stone tools in their regional communities. Stone workers employed jade to make prestigious, beautifully polished versions of utilitarian stone tools, such as axes, and also to make implements with possible ceremonial or protective functions. The status of jade continues throughout Chinese history. Pottery also reached a high level with the introduction of the potter’s wheel.
Neolithic Liangzhu culture
A group of Neolithic peoples grouped today as the Liangzhu culture lived in the Jiangsu province of China during the third millennium B.C.E. Their jades, ceramics and stone tools were highly sophisticated.
Cong
They used two distinct types of ritual jade objects: a disc, later known as a bi, and a tube, later known as a cong. The main types of cong have a square outer section around a circular inner part, and a circular hole, though jades of a bracelet shape also display some of the characteristics of cong. 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 alone had 25 bi and 33 cong. Spectacular examples have been found at all the major archaeological sites.
The principal decoration on cong of the Liangzhu period was the face pattern, which may refer to spirits or deities. On the square-sectioned pieces, like the examples here, the face pattern is placed across the corners, whereas on the bracelet form it appears in square panels. These faces are derived from a combination of a man-like figure and a mysterious beast.Cong are among the most impressive yet most enigmatic of all ancient Chinese jade artifacts. Their function and meaning are completely unknown. Although they were made at many stages of the Neolithic and early historic period, the origin of the cong in the Neolithic cultures of south-east China has only been recognized in the last thirty years.
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.
