The sacrificial record in burial pits of the late Shang Dynasty: evidences from the chroma and magnetic properties of the Sanxingdui site, Sichuan, China

Abstract

AbstractThe Sanxingdui site (4.4–2.9 ka B.P.) in southwestern China is considered one of the most significant archaeological discoveries of the twentieth century, which contains numerous codes for interpreting the origin and development of the Yangtze River civilization. Remains found in Sanxingdui burial pits are keys to deciphering some of these codes. From the characters of the charcoal fragments, ashes and jades in the Sanxingdui buried pits, at the same time, comprehensively analyzing archaeological evidence and previous research results, we speculate that the temperature of ancient Shu people burning sacrifices could be 600–800 ℃. However, the values of magnetic properties and chroma of soils near the ash layers in the pits, and Guanghan Clay near the pits, do not show obvious changes caused by such high-temperature annealing. Combined with the geographical location of the pits and the accumulation characteristics of ash layers and artifacts in the pits, we consider that the Sanxingdui burial pits were not trash pits but sacrificial pits, and they were used for burying sacrifice after burning sacrifice. Although the ritual of burying sacrifice after burning sacrifice dates back to the Longshan period (4.3–4.0 ka B.P.) in China’s Central Plain, the Sanxingdui sacrificial pits, which began to occur in the late Shang Dynasty (~ 3.0 ka B.P.) with such a large scale, and the sacrifices unearthed from the pits, are unique. So, we believe that although influenced by the Central Plain culture, the ancient Shu people in the late Shang Dynasty have unique characteristics of culture and religion.
