Thomas Aquinas was a Dominican friar, theologian and philosopher whose writings became foundational to Catholic scholastic thought. He served in the intellectual world of the papal court and composed liturgical texts for the feast of Corpus Christi at Urban IV’s request. The Saracen portrays him as Fra Tomasso d’Aquino during the debate over a Christian–Mongol alliance.
Aquinas taught in Paris and Italy and produced a vast body of theological and philosophical writing, most famously the Summa contra Gentiles and the unfinished Summa Theologiae. Drawing extensively on Aristotle while engaging Islamic and Jewish philosophers, he developed influential accounts of natural law, ethics, metaphysics and the relation between reason and revelation. Canonised in 1323, he became one of the central authorities of later Catholic theology.
