Bobbio, situated in a gorge of the Apennines thirty-seven miles north-east of Genoa, was founded by Saint Columbanus, a disciple of Saint Comgall, founder of the great monastery at Bangor, in County Down, Northern Ireland. Columbanus died at Bobbio and was buried there in 615. This establishes at once a connection between Bobbio and Bangor, and an examination of the contents of the codex placed it beyond all doubt that it was originally compiled in Bangor and brought thence to Bobbio, although not in the time of Saint Columbanus: there is in the codex a hymn entitled ymnum sancti Congilli abbatis nostri, and he is referred to in it as nostri patroni Comgilli sancti. Again there is a list of fifteen abbots, beginning with Comgall and ending with Cronan, the fifteenth abbot, who died in 691; the date of the compilation, therefore, may be referred to 680-691.
