Born in Rome in 1360, Favaroni entered the Studium at Bologna in 1384, and was bacchalarius formatus in 1389, after having reading his Sentences during 1388-1389. This date is also confirmed by the colophon at the end of his first Principium on folio 159ra (qui legit Bononine 1388 et 1389); in 1392 he became master of theology.
After finishing his studies, we find Favaroni very active in different Augustinian Studia in Italy (Bologna, Lecce, Perugia), during which period he also focused on writing, mainly sermons and a commentary on the Apocalypse, a text that treats the relation between Christ and the Church. In the third tractatus of De principatu pape, dedicated to Cardinal Cosma Magliorati (archbishop of Bologna), who later became Pope Innocent VII, Favoroni develops a different conception than that presented by the likes of Dante in his Monarchia.
In 1416 Favaroni was a professor in the Faculty of Theology of Florence, and during this period he wrote a commentary on books I and II of the Ethics. Another important moment of his life came in 1430, when Pope Martin V empowered Favaroni's confessor, Pietro Assalhit, to go to Ostia and search for St. Monica’s relics for their translation to Rome. Pietro Assalhit took Augustinus Favaroni with him. The same year is also important because of Favaroni's involvement in a process of condemnation. Some propositions from his treatise De sacramento unitatis Christi et Ecclesiae were jugged as being too close to the doctrine of John Huss. These propositions were the object of a second examination in 1436. Therefore, Favaroni defended his position in two different texts: Contra quosdam errores haereticorum and in Defensorium sacramenti unitatis Christi et Ecclesiae. From 1432 to 1435 he participated to the Council of Basel. He spent the last years of his life in Tuscany, and he died in 1443 in Prato, where he is also buried.
