Acquired in London in the beginning of the 1970's this bi disc is carved from a beautiful light celadon jade. On one side is a qilong, a symbol of dynamism and flexibility holding a branch of lingzhi fungus (Longevity) in its mouth. The other side shows eight finely carved stylized bird-like creatures which may be phoenixes. The phoenix symbolizes 'Happiness and Prosperity' and is also said to be able to influence fertility. The style of this disc points at a late Ming (1368-1644 AD) to an early Qing (1644-1912AD) date. Diameter 6.2 cm. Thickness 1.2 cm. Weight 77.0 grams.
