Giles of Rome

Giles of Rome O.S.A. (Latin: Aegidius Romanus; Italian: Egidio Colonna; c. 1243 – 22 December 1316) was a medieval philosopher and Scholastic theologian and a friar of the Order of St Augustine, who was also appointed to the positions of prior general of his order and as Archbishop of Bourges. He is famed as being a logician, who produced a commentary on the Organon by Aristotle, and as the author of two important works: De ecclesiastica potestate, a major text of early-14th-century papalism, and De regimine principum, a guide book for Christian temporal leadership. Giles was styled Doctor Fundatissimus ("Best-Grounded Teacher") by Pope Benedict XIV.

Writers in 14th- and 15th-century-England such as John Trevisa and Thomas Hoccleve translated or adapted him into English.
