Samcheonsa Temple (三川寺) was situated on Mt. Bukhansan in Eunpyeong-gu, Seoul, which was known as Namgyeong during the Goryeo dynasty. It is believed that the stele for National Preceptor Daeji (大智國師) was erected during the reign of King Munjong (文宗, r. 1046‒1083), the eleventh king of the Goryeo dynasty, and the text was composed by Yi-Yeonggan (李靈幹) and written by King Munjong himself in regular script (楷書, Kr. haeseo) in the style of eminent Tang scholar Quyang Xun (歐陽詢). Samcheonsa Temple was at its zenith after the Goryeo period, but is believed to have been destroyed after the Japanese invasion of Joseon. The stele provides valuable information for studying the development of Buddhism in Korea during the early Goryeo period.
