Augustine’s Enarrationes in psalmos, consisting of both spoken homilies and dictated clarifications in the style of sermons, comprises a thorough commentary on the Book of Psalms. Its rapid and widespread reception during the Middle Ages was due to its spiritual and moral exegesis, about which monastic circles were particularly interested. Considered as a whole, the work is a key text for the understanding of the history of biblical exegesis and early Christian rhetoric. This first complete edition, based on a text critical study and a scholarly analysis, aims to provide an alternative to the old Maurist text (Paris, 1681). Because of the extraordinary length of the complete corpus of the Enarrationes in Psalmos and its vast manuscript tradition, the editing project has been divided between two research teams (Vienna / Rome). The volume now being published (CSEL XCV/5), edited by Franco Gori in collaboration with Giuliana Spaccia, contains the last part of Augustine’s commentary, the Enarrationes 141-150. These sermons were delivered by Augustine in the North African cities of Hippo and Carthage, as well as in Utica between 397 and 418 (only the final homily, En. 150, was probably completed after 420).
