A conversation with Alessandra Bucossi (Ca' Foscari University of Venice) and Niccolò Zorzi (University of Padua) on three heresiological texts of the twelfth century, the challenges of publishing and studying them, and how their main concerns can be presented in a museum exhibition. Our discussion is followed by dedicated presentations on each of the three authors by Marco Fanelli (Ca’ Foscari University of Venice) on Zigabenos, Alessandra herself on Kamateros, and Ottavia Mazzon (University of Padua) on Choniates.
