This thesis contains the critical edition of manuscript O [Bibliothèque Nationale de France, fr. 12583] of the Roman de Renart, accompanied by a philological, linguistic and literary introduction, a series of notes on the text, an index of proper names, a lexicon and a bestiary of anonymous animals present in the Roman. Compared to the other manuscripts that make up the Renardian tradition, this late text shows a certain originality since the scribe mixes the multiple manuscript sources. It also offers many independent lessons: interpolations. Their study allows us to grasp the strong variation of medieval stories, the inscription of writing in an essential fluctuation. -[Abstract]
