This calligraphy was written by Lanxi Daolong (1213-78), a monk from the Southern Song Dynasty China and the founder of Kenchoji Temple in Kamakura, Japan. It is said that his arrival in Japan and naturalization brought authentic Song Zen to Japan. In 1253, the regent Hojo Tokiyori established Kenchoji Temple in Kamakura with Lanxi as its founder, and Lanxi had earned the deep trust of Tokiyori. The calligraphy contains a prayer for the peaceful continuation of the reign of Tokiyori’s son, the regent Tokimune (1251-84).
