Abbot of Bobbio, date of birth unknown; died 639 or 640. He was the son of a pagan nobleman in Austrasia and a near relative of Saint Arnulf, Bishop of Metz, whose pious example had such an influence on Bertulf that he became a Christian and in 620 entered the monastery of Luxeuil. A few years later he became acquainted with Abbot Attala, who had come to Luxeuil on a visit, and, with permission of Abbot Eustace of Luxeuil, joined Attala’s community at Bobbio in Italy. Upon the death of Attala, in 627, Bertulf was elected by the monks of Bobbio as their abbot. Like his holy predecessor, he insisted on the observance of the austere rule introduced by Saint Columban, the founder of Bobbio, and preached fearlessly against Arianism, which had gained a firm foothold in Italy under the Lombard kings. When the Bishop of Tortona endeavoured to bring Bobbio under his own jurisdiction, Bertulf hastened to Rome, where Pope Honorius received him kindly and granted the monastery entire exemption from episcopal jurisdiction. Jonas, a monk of Bobbio, who accompanied Bertulf on his journey to Rome, relates that, while returning to his monastery, Bertulf was attacked by a deadly fever, and cured miraculously by Saint Peter. The same author ascribes a few other miracles to the prayers of Saint Bertulf. Most martyrologies give him the title of saint. His feast is celebrated on 19 August.
