Saint Bertulf of Bobbio was a 7th-century missionary and abbot who served the monastery at Bobbio for seventeen years. Born in Metz to an Austrasian nobleman, he entered the Luxeuil monastery in 620 before traveling to Italy with Attala. As the third abbot of Bobbio, he governed the community according to the strict rule established by Columbanus. During his leadership, he worked to combat Arianism and maintained the monastery's independence through direct contact with the papacy.
