This book documents the extraordinarily significant transfers and cultural diffusion between the Mongol Yuan Dynasty of China and Central and West Asia, which had a broad impact on Eurasian history in the 13th and 14th centuries. The Yuan era witnessed perhaps the greatest inter-civilisational contacts in world history and has thus begun to attract the attention of both scholars and the general public. This volume offers tangible evidence of the Western and Central Asian influences, via the Mongols, on Chinese, and to a certain extent Korean, medicine, astronomy, navigation, and even foreign.
