Zen Buddhism doesn’t adhere to characters, but leaves the most written records among all Buddhist schools; the Zen masters didn’t leave a footprint, but left unique heritages on the history of calligraphy. For instance, Chinese literati Zhao Mengfu(趙孟頫)left a significant work which was a written message to his master, The Letter to Chūhō Minpon(中峰明本), but the response letter was drawn in history. Meanwhile, the authentic works of Cyūhou Minpon are only conserved in Japan.
In the Chinese context, the term “Calligraphy Heritage(墨蹟)” can only refer to “manuscript” or “the authentic work of paintings and calligraphies”. However, in the Japanese context, the term “墨蹟(Bokuseki)” specifically denotes the works of Zen masters. Their works in the Song and the Yuan Dynasty (Kamakura period in Japanese History) were perfectly conserved in Japan and considerably affected various aspects of everyday life, including religion, calligraphy, Teaism, etc. This article delves into the study of two iconic Zen Masters: Syūhō Myōchō and Ikkyū Sōjun. Based on one-by-one introductions to their calligraphy works, this study aims to narrate how did the tradition of Bokuseki conservation in Japan substantially influenced the calligraphic expression of the descendants.
