This thesis results of a comparative study of painting and poetry of the XVIth and XVIIth centuries. In this document, painting and poetry throw light on each other, thanks to an analysis of discrepancies and similarities about a same theme, which is the baroque satirical portrait. Our study sets out an aesthetical approach of the baroque visual universe, while it puts an emphasis on the reception of the work of art. The poetry we are about to analyse is straying from classical satire as it is to be found in satirical writing, which uses a colourful and often obsene language. Our thesis is divided into five chapters. First, we will give a definition of the portrait in painting and poetry. We will then show that depicting a human being also means revealing his soul, and that, in these tormented times, the souls appear through ugliness and deformity in social and misogynist portraits. The third chapter will be dedicated to the notion of paradoxical aesthetic, that is to say showing the man and the universe in a reversed way- like an echo to the shattered world at the turn on the XVIth century- with the consequences it implies on the reader. We will then analyse more deeply the misogynist poetry of Sigogne, before ending with the study of the fantasy world of his poetry and of the baroque poetry in general.
