The influence of the celebrated Chinese Southern Song-dynasty (1127-1279) calligrapher Zhang Jizhi (1186-1266) in brush style and the red seals, "Rankei" and "Doryu," at the end of the scroll, indicate that the Zen priest Rankei Doryu (1213-78) copied this manuscript. Rankei Doryu was well known as having received the support of Hojo Tokiyori (1227-63) and becoming as the founder of Kencho-ji Temple in Kamakura.
