Reading Explanations of the Ch'i-heng t'u: An Initial Discussion of New Evidence Regarding the Origins of the Khai Tien Theory

七衡圖是中國古代宇宙論之一的蓋天說解釋天地距離，太陽運行與人際關係的圖象。這種說法有人認為可能早自殷末，現在又從殷虛得到兩種新例，故其來源可能比殷末更早。

The Ch'i-heng t'u is a pattern representing one of the Ancient Chinese cosmic theories, explaining the distance between the earth and the heavens, the movement of the sun and human relationships. While some scholars maintain that explanations such as these may have existed as early as the late Yin period, two instances of new evidence from Yin-hsü illustrate the fact that the origin of these patterns may be traced back to a time preceding the late Yin period.
