Biography/Description |
|
Famous author of the Speculum iudiciale, the most widely used procedural treatise of the Middle Ages. He was born near Beziers in Southern France, in 1236. He studied canon law at Bologna under Bernardus Parmensis and later taught at Modena. Pope Clement IV (1265–68) made him auditor generalis of the Rota, which gave him the practical experience reflected in his chief work. G. attended the Second Council of Lyon in 1274 and later wrote a commentary on the council’s constitutions. The peak of his administrative career was reached when he became rector generalis of the papal states in 1278, which he then exchanged for the rectorship of the new French papal provinces (1281–82). Guillelmus became bishop of Mende in 1286. He died at Rome ten years later. |
