Shu pu, completed in 687, and Xu shu pu, written in 1208, are outstanding among early treatises on calligraphy. Chang Ch'ung-ho and Hans H. Frankel introduce and provide translations and annotations for these important texts. The book 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.
