'In exploring the Latin and vernacular production and reception of Gertrud von Helfta's Legatus divinae pietatis, Racha Kirakosian is redefining late medieval authorship and the value of each redaction within the landscape of late medieval piety. Her book offers innovative and always exciting discoveries as she unpacks the vital transmission of Gertrud's Legatus combining the scribal nature of late medieval piety with the textile culture of religious communities. Groundbreaking research, brilliantly written, a scholarly masterpiece!' Hans-Jocher Schiewer, University of Freiburg
