This volume is a pioneer study focused on a corpus of 89 fragments of exquisitely illuminated manuscripts that were produced under the patronage of the Turkic-speaking Uygurs in the Turfan region of East Central Asia between the 8th and 11th centuries CE. Through detailed analyses and interpretations aided by precise computer drawings, the author introduces an important group of primary sources for future comparative research in Central Asian art, mediaeval book illumination, and Manichaean studies.
