Scholastic theologian. An Englishman by birth, he studied and taught at Paris. In 1142 he went to Melun, where he directed a school; in 1148 he took part in the condemnation of Gilbert de la Porrée at the Synod of Reims. He became Bp. of Hereford in 1163. His Trinitarian doctrine was influential. According to him power is to be especially attributed to the Father, wisdom to the Son, and goodness to the Holy Spirit, without, however, robbing the other two Persons of the quality predicated in a particular way of the one.
