This rubbing of a stone stele records the inspection of the Army of Inspired Strategy by the Tang emperor Wuzong (Li Yan). The text was composed by Cui Xuan and written by Liu Gongquan, both of the Tang dynasty. The stele was erected in the third year of the Huichang era (843 A.D.), but within a century was damaged by soldiers and soon disappeared. Because the stele was erected within the Imperial Palace, rubbings were not easily taken, even when it was still intact. These Song dynasty rubbings, also bound in the Song dynasty, are the only copy in existence. Of the original two volumes, only the first still exists. The provenance of this item is as follows: Jia Sidao (Southern Song); National Institute of History of the Hanlin Academy (Yuan dynasty); the Ming dynasty Palace Treasury; Zhu Gang, Prince of Jin (Ming dynasty); Sun Chengze, Liang Qingbiao, An Qi, and Zhang Rongfang (all of the Qing dynasty).
