Benedictine of the Congregation of Saint-Maur; b. in Compiègne, France, April 30, 1654; d. in Abbey of Saint-Germain-des-Prés, near Paris, Oct. 18, 1721.

Before his death he published only one volume, containing letters from 67 to 440, titled Epistolae Romanorum Pontificium et quae ad eos scriptae sunt a S. Clemente I usque ad Innocentium III … (Paris 1781). (see maurists).
