Veneti
A Gaulish tribe living in Brittany, noted as mariners, considered still to be existing in the sixth century. The people were called Vendotii.
Traditionally, Trephina, daughter of their leader, Warok, marries Cunomorus.
Notes
In The Place-names in Wales (1912) Professor Rhys says:
“… the word Veneti is most likely of the same origin as the Anglo-Saxon wine, a friend, and meant allies; the Irish fine, a tribe or sept, is most likely related, and so may be the Welsh Gwynedd. The Veneti have left their name to the part of Brittany called by the Bretons Guened, Vannes, and it is this name probably that laid the foundation for the tales which trace an army of Cymry from Gwynedd to Guened.”
