Book excerpt: This volume proceeds from a workshop at the XVIII International Conference on Patristic Studies (Oxford, 2019) and presents developments in recent and ongoing research on the complex tradition of Psalter catenae. The twelve contributions cover a wide range of topics, presenting methodological developments and challenges of catena research as well as fresh insights on specific subjects, such as new manuscript finds and the publication of illustrations and captions in catena manuscripts. The studies range from the first Palestinian stages of Psalter catenae to later Byzantine compositions, and beyond: the Oriental versions receive particular attention. The volume offers students and scholars who are less familiar with research on Psalter catenae a taste of its diversity. Those who have already dealt intensively with this tradition and related topics will find useful research tools and interesting new results. Most of the volume is written in English; two contributions are in French and two in German. The printed volume is accompanied by two databases that are made available online, which allow for more complex search queries.
