Concept
Bi (jade)
Summary
The bi is a type of circular ancient Chinese jade artifact. The earliest bi were produced in the Neolithic period, particularly by the Liangzhu culture (3400–2250 BCE). Later examples date mainly from the Shang, Zhou and Han dynasties. They were also made in glass.
A bi is a flat jade disc with a circular hole in the centre. Neolithic bi are undecorated, while those of later periods of China, like the Zhou dynasty, bear increasingly ornate surface carving (particularly in a hexagonal pattern) whose motifs represented deities associated with the sky (four directions) as well as standing for qualities and powers the wearer wanted to invoke or embody.
As laboriously crafted objects, they testify to the concentration of power and resources in the hands of a small elite.
Later traditions associate the bi with heaven, and the cong with the earth. Bi discs are consistently found with heaven and earth-like imagery, suggesting that the disk's circular shape also bears symbolic significance as this description explains:
It is found that these objects testify to early stages of development of cosmological concepts that remained important in Chinese culture during the Warring States and Han periods: the notion of a covering sky (gaitian) that revolves around a central axis, the cycle of the Ten Suns, and the use of an early form of the carpenter's square. These objects were handled by shamans who were the religious leaders of Liangzhu society and the transmitters of cosmological knowledge.
From these earliest times they were buried with the dead, as a sky symbol, accompanying the dead into the after world or "sky", with the cong which connected the body with the earth. They were placed ceremonially on the body in the grave of persons of high social status. Bi are sometimes found near the stomach and chest in neolithic burials.
Jade, like bi disks, has been used throughout Chinese history to indicate an individual of moral quality, and has also served as an important symbol of rank.
