Bobbio

A description of miracles of Columbanus written by an anonymous monk of Bobbio is of much later date.

In the second volume of his Acta Sanctorum O.S.B., Mabillon gives the life in full, together with an appendix on the miracles of the saint, written by an anonymous member of the Bobbio community.

Jonas entered Bobbio after Columbanus' death but relied on reports of monks who still knew Columbanus.
