A remarkably preserved 2,300-year-old bronze wine vessel has been unearthed near a ruin of the Qin Great Wall in China. The Great Wall referenced is an early structure dating back to the Warring States period (325-251 BC), predating later fortifications. The discovery occurred in the Guyuan area of Gansu province, a location familiar to former leader Mao Zedong, who wrote of the Great Wall during the Long March. The vessel’s contents and construction are expected to reveal details about ancient Chinese winemaking techniques and practices. Experts believe this find offers a unique insight into the culture and technology of the Qin dynasty. Further analysis of the wine residue could unlock secrets about ingredients and fermentation methods employed over two millennia ago. This archaeological find links historical poetry with tangible evidence of the past.
