My project centers on an unedited and largely unstudied late medieval lyric compilation, University of Pennsylvania Codex 902, produced at the French court during a crucial, failed attempt at peace in the Hundred Years War. Opening with a powerful set of lyrics that use imagery of female rape to reify internecine strife, this manuscript, I argue, plays with sophisticated internal organization of its lyrics, that it collects from all regions of Francophone Europe, in order to theorize the palliative role of poetic networks in war-torn medieval Europe. By exploring the anthology's content and organization, I argue for a reconsideration of late medieval courtly love lyric as a sophisticated medium in which repetitive poetic tropes created a unifying literary lingua franca in the face of disintegrating and divisive regional allegiances.
