"One of the landslides in the historiography of ancient and medieval philosophy is the recognition of the import and role of the medieval reception and reworking of Proclus’ Elements of Theology. The volume here reviewed, the first of a triad of essay collections on this topic, will no doubt contribute greatly to that recognition. [...] This is a book for specialists, and a scholarly Fundgrube, as shown by the fact that Latin and occasionally Greek quotations are not translated, the high density of information, and the appendices [...]. The book contains a number of invaluable resources [...] I cannot but conclude that this is an important volume [...] and further avenues of research clearly open up in the wake of this volume." – Marije Martijn, in: The International Journal of the Platonic Tradition, 06 October 2021."It must be clear by now that the collection under review constitutes a significant contribution to the exploration of how Proclus’ Elem. theol. and the Book of Causes were received in the Latin West and in Byzantium. This volume of contributions by an interdisciplinary group of experts covers centuries of Proclean influence and familiarizes the reader with a vast array of complex philological and philosophical issues, ranging from details about manuscripts to the most complicated doctrinal controversies." – Sokratis Athanasios Kiosoglou, in: Aestimatio ns 2.2, 31 July 2022.
