The disc in the photos shows age. In his book ‘Jade flowers and floral patterns in Chinese Decorative art’, Prof. Cheng Te-Kún (see introduction) discusses a disc with two bands of fourteen conical depressions one inside the other which according to him may be taken to represent the twenty eight constellations or mansions of the zodiac. This particular disc was found in a Taoist (Daoist) tomb from the Jin dynasty (1115 – 1234 AD). Taoist priests used to decorate their ceremonial robes with such designs as ‘ruyi’ and Yin & Yang symbols and there is no doubt that these patterns, though basically floral, were closely associated with Taoism. Taoists believe that all the elements in nature are evolved from the movement and interacting of the two forces of nature, the Yin and the Yang. This perpetuates a moving power which may be symbolized by a whirling circle. The middle decorative zone of our disc is occupied by twenty eight grooves, fourteen long ones on the outer band and fourteen shorter ones in the centre, whereas the outer rim consists of eight ‘ruyi’ symbols just like the Jin-disc. It is interesting to note that discoidal rosettes of this type were common elements during the Yuan period (AD 1272 – 1368) and it is to this period that we assign our disc although an earlier date cannot be excluded. A similar type of flower (nr 418) is depicted in professor Cheng Te-k’un’s book ‘Jade Flowers and Floral Patterns in Chinese Decorative Art’。
