Albert the Great, Thomas Aquinas, Bonushomo Britto, and Florentius. This General Chapter established a ratio studiorum, or program of studies, which was to be implemented for the entire Dominican Order, that featured the study of philosophy as a preparative for those not sufficiently trained to study theology. This innovation initiated the tradition of Dominican scholastic philosophy which was to be put into practice in every Dominican convent, if possible, for example, in 1265 at the Order's studium provinciale at the convent of Santa Sabina in Rome. Each convent was expected to have an elected Lector to supervise the preparative studies and an elected Master for theological studies. In the next year he was assigned the title of Preacher General. In 1264 a new Master General of the Order of Preachers was elected, John of Vercelli. It was taken as an opportunity to engage in some academic politics, since Humbertus de Romans, Peter's patron, was dead.

In 1269 he was reelected to the office of Provincial of the French Province, and he held the post until he was named Archbishop of Lyons. On 6 June 1272, Pope Gregory X himself named Peter of Tarantaise to be Archbishop of Lyons, a post he held until he was appointed to be Bishop of Ostia. It is said, however, that Peter was never consecrated. He did, however, take the oath of fealty in early December, 1272, to King Philip III of France. Pope Gregory himself arrived in Lyons in mid-November, 1273, intent upon bringing as many prelates as possible to his planned ecumenical council. He met immediately with King Philip III of France. Their conversations were obviously harmonious, since Philip
