Chinese Literature
Canshu 蠶書 "The Book of Silkworms"

The Canshu 蠶書 "The Book of Silkworms" is an agricultural treatise compiled by the Northern Song period 北宋 (960-1126) scholar Qin Guan 秦觀 (1049-1100), courtesy name Qin Shaoyou 秦少遊 or Qin Taixu 秦太虛, style Huaihai jushi 淮海居士. He came from Gaoyou 高郵 (modern Gaoyou, Jiangsu) and was famous as a friend of the writer Su Shi 蘇軾 (Su Dongpo 蘇東坡). In the early Yuanyou reign 元祐 (1086-1093) he became proofreader (zhengzi 正字) of the Palace Library (mishusheng 秘書省) and junior compiler (bianxiuguan 編修官) of the Historiography Institute (guoshiyuan 國史院) as a retainer of Su Shi who was himself appointed professor (boshi 博士 "erudite") in the National University (taixue 太學). In 1094 he was appointed controller-general (tongpan 通判) of Hangzhou 杭州, then of Leizhou 雷州. When Emperor Huizong 宋徽宗 (r. 1100-1125) ascended to the throne, Qin Guan retired and lived in Tengzhou 藤州, where he died. His collected writings are entitled Huaihai ji 淮海集 and Niyou ji 逆旅集.
The book Canshu was written on the base of observations Qin Guan made in Yanzhou 兗州 near Gaoyou, and as a result of talks he had with the women occupied with the raising of silkworms and spinning yarn. In that region, nearly all women engaged in silk production, as the preface says. A closer investigation shows that the text was only brought into the shape of a book by Qin Guan's son Qin Zhen 秦湛, courtesy name Qin Chudu 秦處度. The Canshu is divided into ten chapters talking about the treatment of the moth's eggs (Zhongbian 種變), (Shishi 時食), (Zhiju 制居), cooking the cocoons (Huazhi 化治), (Qianyan 錢眼), (Suoxing 瑣星), (Tianti 添梯), (Che 車), sacrifices to the Goddess of Silk Can Shen 蠶神 (Qishen 祈神), and silk production along the citystates of the Silk Road (Rongzhi 戎治). The text is very short and clear, but comprehensive, so that the statements in the Canshu can be compared with those in the chapter Cansang 蠶桑 of the contemporarian book Nongshu 農書 by Chen Fu 陳旉. It was therefore appended to this book in its edition in the imperial collectaneum Siku quanshu 四庫全書.
The Canshu is China's earliest preserved book describing the business of silk production as a whole. Statements in the early treatises Fan Shengzhi shu 汜勝之書, Qimin yaoshu 齊民要術 or Sishi zuanyao 四時纂要 are very short and selective, and two Tang period 唐 (618-907) books with the title Canjing 蠶經 as well as Sun Guangxian's 孫光憲 book Canshu from the Five Dynasties period 五代 (907-960) are lost.
The Canshu is to he found in the collectanea Shuofu 説郛, Yimen guangdu 夷門廣牘, Bailing xueshan 百陵學山, Zhibuzuzhai congshu 知不足齋叢書, Longwei mishu 龍威秘書, Qingzhaotang congshu 清照堂叢書, Nongxue congshu 農學叢書 and Congshu jicheng 叢書集成.
