Master of the Dominican Order from 1254 to 1263. He studied in Paris and joined the Order there in 1224. He made definitive contributions to the final codification of the Dominican liturgy and to the organization of the Dominican nuns. He was responsible for the incorporation of philosophical studies into the intellectual life of the Order and for the completion of its academic structure, and he skilfully steered it through the worst of the anti-mendicant controversy. His Opus Tripartitum was written for Pope Gregory V as a preparatory document for the Second Council of Lyons; the comments on the schism between Catholics and Orthodox were a factor in medieval and even modern attempts at ecumenism.
