Bonaventure of Bagnoregio (Bonaventura, c. 1217–1274), known as the Doctor Seraphicus, was an Italian Franciscan theologian, philosopher, and cardinal. A student of Alexander of Hales at the University of Paris, he became regent master in theology there alongside his contemporary Thomas Aquinas. Elected Minister General of the Order of Friars Minor in 1257, he guided the Franciscans through a period of internal crisis and is often called the order's "second founder." His commentary on Peter Lombard's Sentences — composed in the late 1250s — remains the most influential medieval Franciscan systematic theology, and his shorter works (Itinerarium mentis in Deum, Breviloquium, the Legenda Maior of Francis) shaped Franciscan spirituality. Created Cardinal Bishop of Albano in 1273, he died at the Second Council of Lyon (1274); he was canonized in 1482 and named a Doctor of the Church in 1588.
