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.
