UGO d'AMIENS (*Hugo Ambianensis* or *Rothomagensis*). — Benedictine theologian and archbishop, born c. 1085, probably in the diocese of Amiens, died at Rouen on 11 November 1164.
A monk of Cluny, he subsequently became prior of Saint Martial (Limoges), abbot of Saint Pancras (Chichester), then of Reading; in 1129 he was appointed archbishop of Rouen. Following the advice of Saint Bernard (*esto patiens, quia es cum malis*) and Peter the Venerable, he governed with great prudence, succeeding in reconciling the freedom of the Church with the friendship of Henry I of England, who died (1135) in his presence after having received absolution. He labored tirelessly against the heresies of Henry of Lausanne and Peter of Bruys. He introduced the feast of the Immaculate Conception at Reading and Rouen.
He wrote several works in a clear style, free from the formalism of the schools: besides a modest collection of letters (PL 192, 1131-38; 179, 670; 186, 1399-1450); the *Vita s. Adiutoris* (PL 192, 1345-53); the *Tractatus in Hexameron* (of which only a small part remains, ibid. 1247-56); the *De memoria* (ibid. 1299-1324, predominantly theological); a brief commentary on the Creed and the *Pater noster* (ibid. 1324-46); *Dialogorum libri septem* (ibid. 1137-1248), in which he expounds the whole of theology with some personal insights; *Contra haereticos libri tres* (ibid. 1255-98), in which he treats with originality the charismatic aspect of ecclesiology.
