Hugolino of Orvieto, O.S.A. was an important Scholastic theologian and Augustinian friar of the fourteenth century, representing the Augustinian School of thought within the theological and philosophical spheres. Later, in 1368, Hugolino was elected as prior general of the Augustinian Order, and later on in 1370, he was consecrated Bishop of Gallipoli. A year later in 1371, Hugolino was appointed as the Latin Patriarch of Constantinople by Pope Gregory XI, and was made the administrator of the diocese of Rimini.
