A prince studying the Koran

A Mongol prince studying the Koran. Original size: 20.3 cm x 26.7 cm. p. 8 no.1. This seems to be a tent mosque. The inscription above the arch on the left, which is either the entrance or the Mihrab, reads 'Allah is the ruler' (or similar). Note: the proportions given in the source seem rather inconsistent with those of the image.
