 A Latin "vita" was written likely in the 11th century, during a flurry of activity which was part of a monastic reform in Brittany under the supervision of the great Benedictine abbeys in the Loire Valley.This reform prompted the writing of a large number of "vitae" of Breton saints, many of which were written by bishops who produced hagiographies themselves in the absence of a monastic cadre.The account is retained (only) in an 18th-c transcription of a 17th-c copy of an unknown text.
