大秦景教流行中国碑
The Nestorian Stele was constructed in 781 as a monument to 150 years of early Christianity in China. It was buried in the ninth century during religious suppression and lay underground until it was discovered in 1625. The top of the monument is adorned not only with a cross but also with the Buddhist emblem of the lotus and the Taoist symbol of the cloud. The writer of the inscription was Jingjing (monk), a monk of the "Luminous Religion,"as well as Buddhism and the calligraphist was Huangbo Xiyun (these two are thought to have later collaborated on some Buddhist writing). It's unclear whether they were commentators or followers of Christianity.
