An shigao （n.d.）， whose real name was Anqing 安清， his pen name being 世高. A Parthian monk who is one of the earliest recorded translators and transmitters of Buddhism into China. He is said to have arrived to Loyang during the reign of Huan （in 148）， and is credited with having translated a large number of sutras. This number， however， varies greatly according to the different canonical catalogues， so it is likely that a large number of these are attributions. He is said to have stayed in China for approximately twenty years.
