An ancient stone was found in the Tang capital of Changan in the early 1620s containing an inscription in Chinese and Syriac. The inscription was identified to have been composed in 781 by the Church of the East. This splendid edition, by a Japanese scholar whose lifework was Christianity in China, contains the full text of the inscription, a translation into English, critical and historical notes, and several forewords. Also included is an introduction describing the Church of the East, the original discovery of the stone, its protection at the end of the Ching Dynasty, and the course of Nestorian Christianity in China from its first settlement to its transformation as a secret society.
