Thomas de Aquino Byzantinus

Scholastic thought in Late Byzantium is an area which remains largely unexplored. The influence of Thomas Aquinas' (1225-74) writings on Byzantine intellectual circles, both Latinophile and Orthodox, has recently attracted revived interest among scholars. The project aims to contribute to the scholarly discussion by producing the source material for the study of this important subject, namely critical editions of Greek translations of, and commentaries on, various works by Thomas Aquinas composed by Byzantine scholars and theologians between the late thirteenth and fifteenth centuries. The majority of these texts remain hitherto unpublished, or partially edited, or published on the basis of a limited number of manuscripts, often lacking information on sources cited therein. Following standard modern methodology, the critical editions, prepared by doctoral students and scholars participating in our project, are based on all extant manuscripts; they comprise a short introduction on the text and the manuscript tradition, while the text is accompanied by an apparatus fontium identifying sources and an apparatus criticus recording all palaeographical and textual phenomena. An index verborum, an index locorum and facsimiles of selected folios of the extant manuscripts are also included. The editions of these texts will shed more light on the philosophical and theological dialogue among distinguished scholars and theologians in the Greek East and the Latin West in a period of intensive intellectual creativity. In this sense, the publication of these texts, in both printed and electronic form, will become an indispensable tool for scholars and students of Byzantine and Western European history and thought.
