As archdeacon at Turin he was a member of the commission appointed by Pope Clement VIII to edit the Liber Septimus decretalium (later known as the Constitutiones Clementinae); and he also wrote Paratitla on the five books of the Decretals of Gregory IX.
His collection was published by John XXII on 25 October 1317, under the title of "Liber Septimus Decretalium", but it is better known under the name of "Constitutiones Clementis V" or "Clementinæ".
A private individual, Pierre Mathieu of Lyons, also wrote a "Liber Septimus Decretalium", inserted in the appendix to the Frankfort (1590) edition of the "Corpus Juris Canonici".
