One of the oldest surviving Korean Buddhas discovered so far is the Yŏn'ga (Revised Romanization: Yeon-ga) Buddha, an image that gives scholars a fair baseline for what images of the early 6th century looked like. The Buddha, the only one of a thousand commissioned to have survived, gets its name from the inscription on its back that mentions a previously unknown Goguryeo reign period. While it was excavated in Uiryong in Gyeongsangnam-do, former Silla territory far from the borders of Goguryeo, the inscription clearly states the statue was cast in Nangnang (present-day Pyongyang), Goguryeo. The statue is valuable because its inscription states a site of manufacture and date of manufacture, generally agreed to be 539. Additionally, the image is clear evidence that statues could move beyond national borders to neighboring states.
