Sarah Kay is one of the most influential medievalists of the past fifty years, making vital, theoretically informed interventions on material from early medieval chansons de geste, through troubadour lyric, to late medieval philosophy and poetry, in French, Occitan, Latin, and Italian. This volume in her honour is organised around her six major monographs, published between 1990 and 2017. Its essays engage in critical, constructive dialogue with different aspects of Kay’s work, and envisage how these might shape medieval French as a discipline in coming years or decades. The subject matters demonstrate the richness of the discipline: animal studies, musicology, temporality, the material turn, medieval textuality, feminism, queer theory, voice, medieval and modern intellectual formations, psychoanalysis, philology, visual arts, transversal criticism, the literary object, affect, rhetoric, body, the past, modern responses to medieval forms and tropes, non-Christian texts and thought-patterns, politics. Reiterating Kay’s engagement with medieval literature’s complex philosophical debates and analytical scrutiny of human knowledge and affect, they follow her in emphasising how the pleasure of reading medieval literature depends crucially on that literature’s intellectual robustness. These essays shed new light on a range of canonical and less well-known medieval texts and artefacts, to present a fresh perspective on the field of medieval studies.
