The Bolognese nun Diodata Malvasia was presumed to have authored only one work, The Arrival and the Miraculous Workings of the Glorious Image of the Virgin (1617). In her recently discovered second manuscript chronicle, A Brief Discourse on What Occurred to the Most Reverend Sisters of the Joined Convents of San Mattia and San Luca (1575), her writing demonstrates active resistance to Tridentine convent reform. Together, Malvasia’s works read as the bookends to a lifelong crusade on behalf of her convent.
