Aspects of the Breton transmission of the Hibernensis

Brittany played a major role in the early transmission of the Collectio canonum hibernensis. In total, seven copies of the Hibernensis (and a fragment) were written in Brittany or copied from Breton exemplars, and all complete copies of the Hibernensis but two have Breton connexions. The present paper examines how the Hibernensis figured in ninth-century Breton ecclesiastical politics, and introduces new evidence pertaining to individual Breton copies of the Hibernensis and their relationship.
