Following on from last year's lecture (" La peste noire "), and the three study days that accompanied it (" Nouvelles recherches sur la peste noire "), this year's lectures will attempt to draw out all the consequences from the point of view of the narrativity of historical narrative and its causalities. Delving into the archival and textual memory of the event (the Black Death between 1347 and 1352, understood as the paroxysmal moment of the second plague pandemic), but also into the archives of the living world and all those now made available by the environmental sciences, last year's reflections subjected the traditional narrative to a number of disciplinary overflows. From this point of view, the question arises : at what level should we tell this story, which is both global and discontinuous ?
We will attempt to answer this question by drawing on fresh research into the political, economic and social, as well as spiritual and religious, context of the time of the plague. It embraces both questions that historiography has been asking for a long time (the crisis of the late Middle Ages, its relationship with the reorganization of public authorities) and more recent ones, relating in particular to landscapes and habitat, to the environment in general, and to the history not only of demographics but also of the health of the surviving populations. It proposes to grasp this history not only after the plague, but " depuis " as an event, a duration and a temporality.
