Liuyi zhiyi lu 六藝之一錄

Liuyi zhiyi lu 六藝之一錄 is a compendium of "one of the six arts", namely calligraphy (or writing), compiled during the high Qing period 清 (1644-1911) by Ni Tao 倪濤 (1669-1752), courtesy name Kunqu 崑渠 or Kunshen 崑深, from Qiantang 錢塘 (today part of Hangzhou 杭州, Zhejiang). Of his writings, the books Shuijingzhu leichao 水經注類鈔, Wulin shike ji 武林石刻記 and Wenfang sipu 文房四譜 have survived.

The main text has a length of 406 juan, while the appendix (Xubian 續編) has 12/14 fascicles. The book was produced under precarious conditions, and Ni's wife and daughter helped him with the manuscript. Its edition in the imperial series Siku quanshu 四庫全書 was based on this manuscript. The original manuscript was later owned by Pan Hongcha 潘紅茶, but the preserved versions are all incomplete.

The Liuyi zhiyi lu consists of six parts or "collections" (ji 集), each representing one aspect of calligraphic art. These are inscriptions on bronze vessels (Jinqi kuanzhi 金器款識), stele inscriptions (Keshi wenzi 刻石文字), model calligraphies and their theory (Fatie lunshu 法帖論述), writings styles through the ages (Gujin shuti 古今書體), calligraphy theory in history (Lichao shulun 歷朝書論), and notes on calligraphy (Lichao shupu 歷朝書譜). Ni's book covers so many aspects and quotes from an abundant treasure of literature that it can be called a kind of encyclopaedia on traditional calligraphy, all the more as Ni's guiding principle was not to add his own commentaries. Another principle was, however, not to critically change original texts, for which reason the compiler also recorded mistakes and contradicting statements.

The appendix of the Siku quanshu edition has a length of 12 juan, but that in the Siku quanshu zhenben chuji 四庫全書珍本初集 is arranged in 14 juan.
