Late Shang divination and religion
Although certain complex symbols painted on Late Neolithic pots from Shandong suggest that primitive writing was emerging in the east in the 3rd millennium, the Shang divination inscriptions that appear at Xiaotun form the earliest body of Chinese writing yet known. In Late Shang divination as practiced during the reign of Wuding (c. 1250–1192 bce), cattle scapulae or turtle plastrons, in a refinement of Neolithic practice, were first planed and bored with hollow depressions to which an intense heat source was then applied. The resulting T-shaped stress cracks were interpreted as lucky or unlucky. After the prognostication had been made, the day, the name of the presiding diviner (some 120 are known), the subject of the charge, the prognostication, and the result might be carved into the surface of the bone. Among the topics divined were sacrifices, campaigns, hunts, the good fortune of the 10-day week or of the night or day, weather, harvests, sickness, childbearing, dreams, settlement building, the issuing of orders, tribute, divine assistance, and prayers to various spirits. Some evolution in divinatory practice and theology evidently occurred. By the reigns of the last two Shang kings, Diyi and Dixin (c. 1101–1046 bce), the scope and form of Shang divination had become considerably simplified: prognostications were uniformly optimistic, and divination topics were limited mainly to the sacrificial schedule, the coming 10 days, the coming night, and hunting.
