This mural was found on the west wall of the tomb passage of Prince Zhanghuai of the Tang Dynasty. It vividly records the scene of a polo game, in which the competition is fiercely underway with the steeds galloping and the riders swinging their mallets. The combination of the static scenery of the mountains with ancient trees and the dynamic scene of the game forms a sharp contrast between movement and stillness, showing the unique artistic conception of the painter. The figures and horses are outlined to improve the texture, with the colors treated specially for better images and more intense contrast so that the painting stands out in a vigorous style. Polo originated in Persia (present-day Iran) and spread eastward to China via the Silk Road. It gained widespread popularity in the Tang period and was highly favored by the royals. This mural is the earliest and best-preserved visual record of polo in ancient China, offering a window into its popularity and the lifestyle of the Tang elite.
