吐魯番=Turpan; 大桃兒溝第9窟=cave 9 at the Great Peach Valley Grottoes; 八十四大成就者=Eighty-Four Mahasiddhas; 敦煌=Dunhuang; 回鶻文《八十四大成就者傳》=Biography of Eighty-Four Great Mahasiddhas in Uighur
There are images depicting the motif of the Eighty-Four Mahasiddhas drawn in cave 9 at the Great Peach Valley Grottoes. The names of many of the siddhas have been verified by analyzing the images and consulting Uighur manuscripts, while the identities of others require further investigation. By comparing these images with descriptions found in the Uighur texts unearthed from the northern area of the Mogao Grottoes,researchers were able to reconstruct the original order and positioning of the siddhas in this cave. On the basis of the above analyses, two conclusions have been reached that shed light on the history of artistic production and the structure of the regional belief system. Firstly, the images of the Eighty-Four Mahasiddhas in cave 9 are based on the text of Biography of Eighty-Four Great Mahasiddhas, which was unearthed from the northern area of the Mogao Grottoes. Secondly, the consistency between the image of the great siddhas in cave 9 and the description of the same motif in the Biography of Eighty-Four Great Mahasiddhas indicates that belief in the EightyFour Mahasiddhas was the same in both Turpan and Dunhuang.
