Ambrose, Autpert a French Benedictine monk, and abbot of St. Vincent de Voltorne, about 760, in the time of Pope Paul, and Desiderius, king of the Lombards, as he himself tells us. He died July 19, 778. He wrote a Commentarius in Apocalypsin (Colossians 1536, fol.), also published in the Bibl. Patrum. 13, 403, and some other works, viz., Commentaries on the Psalms and Song of Solomon, the Combat between the Virtues and Vices, which goes under the names of St. Ambrose, and is inserted in the works of Augustine; a Homily on the Reading of the Holy Gospel (among the works of St. Ambrose), and another on the Assumption of the Virgin (which is the eighteenth of Augustine de Sanctis), and others.
