Yuan An Stele
In 1929 a commemorative stele recording landmarks in Yuan An's life was uncovered at Yanshi (偃師) county, Henan province. It had been erected around 117, several decades after his death. The stele, 137.5cm tall and 71.5cm wide, is now held at Henan Provincial Museum. It provides dates of his appointments and death not found in his official biography in Hou Han Shu and is the earliest known example of a monumental stele in China. It matches a similar stele found in 1923, that of his son Yuan Chang. The two may have originally been erected at the same location.
