The SanXingDui Museum showcases the bronze and jade art of an ancient civilization in the Shu Kingdom, carbon-dated to approximately 1200-1100BCE. The archaeological site was unearthed in 1987 in a bend of the "Duck" River (YaZi He) in Sichuan Province, at a point where three large barrows stood on the curving bank, much like stars near a crescent moon. The spot was always known as "Three Stars Mound", and after the discovery of bronze relics in the mounds, the forgotten people who once thrived there were given that name. The dates from the radio-carbon tests placed the SanXingDui in the kingdom of Shu which was conquered by the Emperor Qin in the 300's BCE. No record of the SanXingDui people existed in Chinese History during the Spring and Autumn period or during the Unification period. It seems the SanXingDui people were somewhat isolated; because their bronze technology was later than other bronze-age civilzations and because the style of their engravings and figures seemed only loosely reminiscent of earlier designs, the SanXingDui style is very distinct and unlike what most people would associate with typical "Chinese" style.
