The old man holding a staff and herding the goats shown here can be identified as Su Wu (142–60 BCE), the Chinese envoy who tried to negotiate peace with the Xiongnu, the ancestors of the Mongols. The king of the Xiongnu wanted Su Wu to defect, but he refused. As a result of Su Wu’s loyalty to China, the Xiongnu ordered him to herd goats by the shores of Lake Baikal, saying he could return to China “when the male goats give birth.” During the next nineteen years, Su Wu used his official staff to herd goats in the freezing climate and was sometimes reduced to eating snow and wool.
Finally Su Wu was released. He had left China in his prime but returned an old man. He became a national hero, and his loyalty provided a model for later generations.
