As one of the representative caves of the Early Tang period at the Mogao Grottoes,Cave 220 has an inscription dating to the 16th year of the Zhenguan era as well as large-sized sutra illustrations that cover the entire walls,hence this cave has attracted wide attention.However,most research thus far is about the relationship between the Western Pure Land illustration on the south wall and the Amitayus Sutra.This paper mainly addresses how in the peaceful Later Tang period people’s opinions about Pure Land changed greatly,thus a new style of Buddhist art was created,completely free from the Sui Dynasty Buddhist art influence,as verified by cave 220 and especially the Western Pure Land illustration on the south wall of this cave.
