In this seminar we will explore how premodern literary texts imagined experiences of ‘unknowing’: narrating scenes of astonishment, misapprehension, and disbelief. Our primary readings will draw on a rich tradition of vernacular writing in medieval England. We will read across that tradition’s genres, as writers experimented with ways to represent the wondrous, the occluded, the incomprehensible, and the horrific in a variety of forms, among them spectacular miracle plays, prose exercises in mystical negation, and the poetry of dreamworlds and alchemical secrecy.
