Electranne

Electranne (in Latin Electrannus) was bishop of Rennes in the 9th century, attested in 866, and is venerated as a saint in the Western Church. The record gives the day of 2 September.

He was consecrated on 29 September 866 by Hérard, archbishop of Tours, assisted by two of his suffragans, Robert of Le Mans (856 to about 880) and Actard of Nantes. The ceremony conformed to the directives set by Pope Nicholas I to Festinian of Dol in his letter of 17 May, in accordance with the agreement concluded with King Solomon of Brittany, to calm the tensions born of Nominoë's political will to create a "Breton archdiocese" around Dol at the expense of the archbishopric of Tours, which thus lost several suffragans. This submission to Tours, however, seems to have had no follow-⁠up.

Electranne received a certain Fromond, who came on pilgrimage to the tomb of Saint Marcellinus. He is mentioned as a witness in a charter of 2 May 871 in the cartulary of Redon. The source at hand says nothing else of his life.
