This blog "Le Moyen Âge pour Laboratoire" presents and records the sessions of the eponymous seminar coordinated by Florent Coste, Nathalie Koble and Amandine Mussou and supported by Université Paris Diderot and ENS Paris. Between 2018 and 2020 (7 sessions per year), the seminar focuses on how medieval literature could help us make literary theory differently. It aims at fully assuming this theoretical creativity in an experimental and joyful way, in order to read medieval texts in a new way, in their own astonishing actuality. It adresses not only medievalists, but also specialists from other periods and non-specialists curious about literary questions. The seminar notebook will be used above all to announce and report on the monthly meetings. It also gathers reading notes or informations on publications or correlated event.
