Theologian. Educated at Chartres under Fulbert, he became director in 1029 of the school of Saint Martin of Tours, and in 1039 Archdeacon of Angers. His teaching concerning the Holy Eucharist was attacked by Hugues of Langres, but he appealed to the authority of Eriugena. Lanfranc, Abbot of Le Bec, declared Eriugena’s teaching heretical, and obtained the condemnation of Berengarius, who was cited before a Roman Council, but was unable to attend as King Henry I imprisoned him. He finally submitted after 1080, and retired into solitude on the island of Saint Cosme near Tours, and died reconciled to the Church.
