本文題為〈「〈離騷〉稱經」與漢代章句學〉，兩漢楚辭學者評論《楚辭》， 是將其與《詩經》平列比較看待，〈離騷〉一篇甚至因此而稱〈離騷經〉；但是， 將〈離騷〉一篇稱為「經」，是何人所為，卻成為《楚辭》學史中的公案。或 說是屈原，或說是宋玉、景差，或說是漢代淮南王劉安、劉向、揚雄、王逸等 人，更有說是王逸其後不知名之人所為，眾說紛紜，蔚為大觀。本文列舉各家 之說，加以評議；並分析漢代章句學的興起、章句體的特色與弊病，此為王逸 作《楚辭章句》的文化學術背景，而王逸稱〈離騷〉為經，亦與漢代章句學的 發展、章句體的形式密切相關。

As the title of the essay “Li-Sau as Gin” and Han’s Dynasty’s Poetics on Essays suggests, “Chu-Tze” has always been equally seen as “Shi-Gin” in the eyes of scholars on Chu-Tze. Thus, the “Li-Sau” chapter has been occasionally termed as “Li-Sau Gin.” However, who started to call “Li-Sau” as a “Gin” has become an issue of controversy ever since. It has been proposed that this person could have been Chi-Yan, Son-Yi, Jim-Chi, or Liuo-An, Liuo-Sien, Yang-Shon, and Wong-Yi from Han Dynasty; or some unknown person after Wang-Yi. In this paper, theories from all the above-mentioned authors will be presented as well as critiqued. Furthermore, the rise of poetics on essays of Han Dynasty will be analyzed, together with its characteristics and weaknesses, which in all had provided a cultural as well academic background for Wang-Yi’s “Poetics of Chu-Tze”. Thus, Wang’s calling “Li-Sau” as “Gin” is closely connected with the development of Han Dynasty’s poetics on essays as well as its formats.
