Among the noteworthy bishops are: Saint Felix (550-83), whose municipal improvements at Nantes were praised in the poems of Venantius Fortunatus, and who often mediated between the people of Brittany and the Frankish kings; Saint Pacharius (end of 7th century); Saint Gohard (Gohardus), martyred by the Northmen in 843, with the monks of the monastery of Aindre; Actardus (843–871), during whose time the Breton prince Nominoe, in his conflict with the metropolitan see of Tours, created a see at Guérande, in favour of an ecclesiastic of Vannes, in the heart of the Diocese of Nantes; the preacher Cospeau (1621–36).
