Redones
The Redones or Riedones were a Gallic tribe dwelling in the eastern part of the Brittany peninsula during the Iron age and subsequent Roman conquest of Gaul. Their capital was at Condate, the site of modern day Rennes.
In 57 BC they were subjugated by the Romans under forces led by Publius Licinius Crassus, the son of the triumvir Marcus Licinius Crassus, but they provided men to the Gallic coalition led by Vercingetorix at the Battle of Alesia in 52.
Name
They are mentioned as Redones by Caesar, Rhedones by Pliny, Rhiḗdones, Rhḗdones and Rhēḯdones by Ptolemy, and as Redonas in the Notitia Dignitatum. Their chief town is also attested on inscriptions as civ]itas Rieditas Ried.The Gaulish ethnonym Rēdones means 'chariot-drivers' or 'horse-riders'. It stems from the Celtic root *rēd- attached to the suffix -ones.
The original Rēdones led to a form Riedones after diphthongisation. Following the discovery of inscriptions featuring this variant in the 1960s, some historians, including Anne-Marie Rouanet-Liesenfelt and Louis Pape, have argued that the form Riedones should be preferred over Redones in scholarship, which is not necessary according to linguist Pierre-Yves Lambert.
The city of Rennes, attested ca. 400 AD as civitas Redonum is named after the Gallic tribe.
Geography
They lived on the peninsula of Brittany in the region which was known at the time as Armorica. Although they controlled a narrow coastline in the southern part of the Mont-Saint-Michel Bay, they did not have a direct opening to maritime trade. Caesar mentions them among the civitates maritimae or Aremoricae. Their territory was located east of the Coriosolites, north of the Namnetes, west of the Aulerci Diablintes, and southwest of the Venelli and Abrincatui.Their capital was known as Condate Redonum, and was at the site of modern day Rennes.
