theologian. He taught in the cathedral school at Laon. His lectures on the Bible discussed points of interest as they arose; after his death these lectures were reworked and enlarged into systematic Summae. He was traditionalist in his views, but his methods were new. The corpus of his work is not settled, but he certainly arranged commentaries on the Psalter, the Pauline Epp., and Jn., which are the foundation of the Glossa Ordinaria.
