(Also: Duranti or Durantis). Canonist and one of the most important medieval liturgical writers; born about 1237, at Puimisson in the Diocese of Béziers, Provence; died at Rome, 1 November, 1296. He was called Speculator from the title of one of his works, Speculum Judiciale. He studied law at Bologna under Bernard of Parma and then taught it at Modena. Clement IV (Guy Foulques, 1265-1268, also a Provençal) summoned Durandus to Rome, ordained him subdeacon, and gave him titular canonries at Beauvais and Chartres. He was then attached to the papal curia as Auditor generalis causarum sacri palatii. He accompanied Gregory X (1271-1276) to the Second Council of Lyons (1274) and as the pope's secretary, drew up its decrees. In 1279 he was made dean of Chartres, but did not reside there. At about the same time he went to Romagna as papal governor and succeeded in subduing a rebellion under Guy of Montefeltro. He destroyed Guy's fortress della Ripa and founded in its place the town of Urbania In 1286 he was elected bishop by the chapter of Mende (Mimatum) in the province of Narbonne, but did not go into residence till 1291. Meanwhile his diocese was administered by his nephew, William Durandus the younger. In 1295 he was again in Italy (under Boniface VIII, 1294-1303) as governor of Romagna and Ancona, where the Ghibellines were again in rebellion. He refused the pope's offer to make him Archbishop of Ravenna, came to Rome, and died there. There is no reason to suppose that Durandus belonged to any religious order, though he has been claimed by both the Dominicans and the Austin Canons. He is buried at Rome in Santa Maria Sopra Minerva, where a long epitaph tells the story of his life and gives a list of his works.
Of these works the most famous is the Rationale divinorum officiorum (first ed. by Fust and Schoeffer at Mainz, 1459, and reprinted frequently). It was written in 1286. Its eight books contain a detailed account of the laws ceremonies, customs, and mystical interpretation of the Roman Rite.
