Yunshizhai bitan 韻石齋筆談

Yunshizhai bitan 韻石齋筆談 "Brush talks from Rhyme Stone Studio" is a "brush-notes"-style book (biji 筆記) written during the early Qing period 清 (1644-1911) by Jiang Shaoshu 姜紹書 (died c. 1680), who is also known for his art book Wusheng shishi 無聲詩史.

The book is divided into two juan, with a total number of 58 small chapters. It records observations on ancient artifacts, calligraphy, paintings, and curiosities, offering analyses of their merits and faults, comparisons of similarities and differences, and assessments of authenticity, all accompanied by discussions and commentary. The author quotes from older texts like the book catalogue Yuge cangshu 裕閣藏書, the encyclopaedia Yongle dadian 永樂大典 and stories about eminent persons. The second juan contains miscellaneous discussions, for instance, on music, white rabbits, sand pheasants (shazhi 沙雉; Gallinago spec.), and the jade belts worn by civil officials. These entries vary in relevance to the themes of the book's first part and seem to be casual notes recorded at will.

The structure of this book models Zhou Mi's 周密 (1232-1298) Yunyan guoyan lu 雲煙過眼錄, but whereas Zhou's book focuses on collectors, Jiang's book is based on the objects themselves. Jiang gives detailed accounts of the condition of the objects and the history of their acquisition and transfer among collectors. The map Tiancheng taiji tu 天成太極圖, for instance, was found by chance on a round stone, with black and white alternating structures in the area symbolising the taiji. This contradicts Zhu Xi's 朱熹 (1130-1200) claim that the taiji (Supreme Ultimate) was formless. The Cross Stele of Yanling (Yanling shizi bei 延陵十字碑) gives evidence disproving the claim that Confucius never visited the region of Wu 吳. The book also discusses the tripod Huangshi Wenwang ding 黃石文王鼎 attached to antiquarian illustrations in the book Bogutu 博古圖; the jades seal found in 1624 was not dating from the Qin dynasty 秦 (221-206 BCE), and the Hezhuang chunhua tie 河莊淳化帖 as not being a copy from Wang Zhu 王著 (d. 990), but rather a reprint from the Song period 宋 (960-1279). The book's arguments are well-supported with evidence and can be referenced for research.
