據敦煌本〈捉季布傳文〉文末記載：「具說《漢書》修製了，莫道詞人唱不真。」可見詞人的講唱底本是源自於《漢書》，然經比對《史記》與《漢書》季布傳，《漢書》內容幾乎因襲《史記》而來，僅是用字減省的差異，故追本溯源，乃採《史記．季布傳》為研究文本之一。而本文是運用互文性理論，依據互文性要素，探究敦煌本〈捉季布傳文〉與《史記．季布傳》兩文本的互文性關係。又敦煌本〈捉季布傳文〉是講唱文學的代表，屬於俗文學的範疇，而《史記．季布傳》則是史傳文學，所以文中兼論俗文學對史傳文學的傳承與創新。

According to the Dun-Huang version of the ＂Catching Ji Bu＂, ＂the poem's speech is derived from the＂ History of Former Han＂, however by comparing Biology of Ji Bu in the ＂Record of Grand Historian＂ and ＂History of Former Han＂ we found that the content was almost from the ＂Record of Grand Historian＂ only to reduce some script, so we trace back the source to investigate Biology of Ji Bu in ＂Record of Grand Historian＂ as one of the research texts. The intertextuality theory is used to explore the intertextuality between Dun-Huang version of the ＂Catching Ji Bu＂ and Biology of Ji Bu in ＂Record of Grand Historian＂. Moreover, Dun-Huang version of the ＂Catching Ji Bu＂ is one of the representative of singing literature, belongs to the category of popular literature, in the other hand, Biology of Ji Bu in ＂Record of Grand Historian＂ belongs to literature of historical biology, so we also analyze innovation of the popular literature and the inheritance from the literature of historical biography.
