The Memorial of the Propagation in China of the Luminous Religions from Daqin was inscribed on a stone stele erected in 781 in one of China’s ancient capitals, Chang’an (now Xi’an). The stele was discovered in the seventeenth century and has given historians and archaeologists their first insights into early Christianity in China, which had arrived from Syria (“Daqin”) and was embraced by the emperors of the T’ang Dynasty. The excerpts express Christian doctrine about the creation of the world, the birth of Christ, and the arrival of Christian monks in China. Section 23 is a poem of praise that recapitulates many of the assertions of the text and summarizes how, under a succession of T’ang emperors, Christianity brought light and truth to the people of China.
