Purpose of my thesis is create a precise register of inversion in chante-fable from XIIIth century: Aucassin et Nicolette. Main point of view is connected with a converse of woman and man part. This noticeable destabilization brings an inversion of further rules defined by literary discourse of medieval literature, above all by courtly culture. The first part included a basic definitions of misogyny, courtly love, chivarly and carnival principle. Following analysis of Aucassin et Nicolette indicates medieval need to show aberrations from social order and tries to find way to cure that "illness" of age.
