In spite of a wide range of studies, the chancellor of the university of Paris Jean Gerson (1363-1429) remains quite unknow as a litterary author and his texts are mainly read in a theological or historical way. Thus, this study will focuse on a rhetorical and stylistic approach of the texts so that they can be understood in a litterary frame. Allegorical devices, images but also auctorial strategies are some of the elements that show the integration of court culture in the homely. In the same time, we will try to consider in a new way Jean Gerson's role and place in the intellectual context of late Middle Ages.
