This study examines the motivations and doctrinal coherence of the Commentary on the Elements of Theology of Proclus written by Berthold of Moosburg, O.P. († c. 1361/1363). It provides an overview of Berthold’s biography and intellectual contexts, his manuscript remains, and a partial edition of his annotations on Macrobius and Proclus. Through a close analysis of the three prefaces to the Commentary, giving special attention to Berthold’s sources, it traces the Dominican's elaboration of Platonism as a soteriological science. The content of this science is then presented in a systematic reconstruction of Berthold’s cosmology and anthropology. The volume includes an English translation of the three fundamental prefaces of the Commentary.The publication of this volume has received the generous support of the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme through the ERC Consolidator Grant NeoplAT: A Comparative Analysis of the Middle East, Byzantium and the Latin West (9th-16th Centuries), grant agreement No 771640 (www.neoplat.eu)."This is, indeed, a precious insight into the spirit of Berthold’s philosophical thinking. Overall, the monograph’s ambition seems to be both to represent a starting point for new readers interested in Berthold, and to stress the philosophical value of the Commentary: both goals are most certainly reached."-Giuseppe Thomas Vitale, Thomas-Institut der Universität zu Köln, Recherches de Théologie et Philosophie médiévales 89.2
