Mathieu Pernot joins the tradition of political art nourished by history and sociology. He proceeds with series, which include many analytical and successive points of view on the main political and social questions of identity and memory, alienation and progress. If he masters the agreements of the social documentary (series, frontality, precision, neutrality), it is to greater exceed them, in the tense images of the Hurleurs, or in the spectral details of the Témoins that reuse existing images.
