"Shu pu", completed in 687, and "Xu shu Pu", written in 1208, are among early treatises on calligraphy. This work introduces and provides translations and annotations for these texts. It also includes a facsimile and a transcription of the original "Shu pu" and a transcription of "Xu shu pu" (the original is not extant), together with a glossary of calligraphic terms, an appendix of persons mentioned, and a full bibliography. Because the concepts of calligraphy developed in tandem with theories on painting and literature, treatises on these three arts use similar ideas, terms, and images. The treatises in this volume should therefore be of interest to students in all these fields.
