Stephen of Autun

Bishop, liturgical writer, b. at Bangé (hence surnamed Blagiacus or de Balgiaco) in Anjou; d. at the abbey of Cluny, 1139 or early in 1140. Of his younger days nothing is known except that he was the son of Gaucerannus, lord of Bange, and the uncle of Humbert, Archbishop of Lyons. He appears in history (1112) as Bishop of Autun. As such he was present (1115) at a synod of Tournus. A letter is in existence of the year 1116, written to him from the Lateran by Pascal II in which the pope places the Diocese of Autun under his special protection and confirms to Stephen various privileges. In 1129 Stephen was among the prelates who assisted at the coronation of Philip, eldest son of Louis VI of France. He built a cathedral, beginning in 1120, which was solemnly consecrated (1131) by Pope Innocent II. He always showed a great admiration for the religious state, and in 1136 resigned his see and entered the monastery of Cluny. The abbot, Peter the Venerable, under whom he entered and died, gives great praise to his learning and piety. His "Tractatus de Sacramento Altaris", printed together with some other documents relating to Stephen, in P.L., CLXXII, 1371, is an ascetico-liturgical treatise, consisting of twenty chapters and a preface, in which he speaks of the ordination and duties of each of the Minor and Major Orders; and of the Holy Sacrifice of the Mass and gives a literal and allegorical explanation of the Canon. He is one of the earliest writers using the term transubstantiation . This treatise, published in 1517 by Montalon, canon of Autun, was ascribed by some to Stephen II of Autun (d. 1189), but is vindicated for the earlier bishop by Mabillon, "Annales O.S.B.", VI, 270.
