Career
While King Louis of France was engaged upon his expedition in Palestine, he visited the king and queen at Joppa, Sidon, and Acre. King Louis desired him to make a visit to France. To ensure the presence of so distinguished a prelate at his own court, Pope Alexander IV made him Bishop of Vicenza, in 1256.
He wrote a commentary on the "Hierarchy" of Saint Dionysius the Areopagite, of two volumes of sermons, and some smaller works.
