1657-1709. French Benedictine scholar. Born at Reims, he studied in his native city before entering the Benedictine abbey of St.-Remi in 1674. Eventually he went to the monastery of St.-Germain-des-Prés, the great center of Maurist* learning. Here he became a pupil and friend of Jean Mabillon, with whom he collaborated in producing volumes VIII and IX of Acta sanctorum ordinis sancti Benedicti (1701). Ruinart's quiet life in the monastery enabled him to pursue his academic aims, and among other books he wrote A Life of Jean Mabillon, A Life of Pope Urban II, and An Apology for the Mission of St. Maurus.
