  Giles of Rome (who died in 1316 as archbishop of Bourges) was one of the most productive and influential thinkers active at the end of the 13th century, who played a major role also in the political events of his time. Giles of Rome was an extremely prolific author and left a very large corpus of writings, encompassing commentaries on Aristotle, theological treatises, questions, and sermons. In the last couple of decades, a research group originally led by Francesco Del Punta (Scuola Normale Superiore, Pisa, Italy; died in 2013) has been devoting a lot of energy to the project of publishing his Opera Omnia and deepening our knowledge of his thought. Although this group has produced extremely significant results, enriched by the contributions of other scholars, an assessment of Giles’ whole work is still in progress. For this reason, the present entry only aims at providing insight into an ongoing process of research.
