<Li> The Osismii, who lived in the western part of Brittany . Their territory comprised the Finistère département and the western extremity of Côtes - d'Armor and Morbihan . </Li> <Li> The Redones (or Rhedones), who lived in the eastern part of the Ille - et - Vilaine département . They gave their name to the city of Rennes (Roazhon in Breton language, in the center of the département) and to the town of Redon (in the south of the département, bordering the département of Loire - Atlantique in the administrative région of Pays de la Loire, where its suburb town of Saint - Nicolas - de-Redon is located; however the city of Redon was founded around AD 832 under the initial name of Riedones, long after the Redones people were assimilated to Bretons; the cultural link between Riedones and the former Redones people is highly probable but difficult to recover and the name of Riedones may have been written from a local usage preserving the name of the former people in the vernacular oral language from a reading of an ancient Greek othography). </Li> <Li> The Veneti, who lived in the present Morbihan département and gave their name to the city of Vannes . Despite confusion by the classical scholar Strabo, they were unrelated to the Adriatic Veneti . </Li> <P> Those people had strong economic ties to the Insular Celts, especially for the tin trade .

The last four peoples mentioned by Caesar were respectively located in Cotentin (Lower - Normandy), pays de Caux (Upper - Normandy), Limousin (Aquitany) and the location of the Ambibarii is unknown . The Caletes are sometimes also considered as Belgians and" Lemovices" is probably a mistake for" Lexovii" (Lower - Normandy). </P>
