An Shigao
An Shigao (, Korean: An Sego, Japanese: An Seikō, Vietnamese: An Thế Cao) (fl. c. 148-180 CE) was an early Buddhist missionary to China, and the earliest known translator of Indian Buddhist texts into Chinese. According to legend, he was a prince of Parthia, nicknamed the "Parthian Marquess", who renounced his claim to the royal throne of Parthia in order to serve as a Buddhist missionary monk in China.
