in northern Brittany, sometime in the period 511–558, who killed the local
‘hereditary’ ruler Jonas and displaced him until Jonas’ son Idwal was instated.
Nowitso happens that Idwal’s dynasty was associated with the Breton province
of Dumnonia. Is it possible that the British Dumnonian king went adventuring
across the Channel? And is it possible that this, or a similar adventure, is
responsible for the transfer of the name ‘Dumnonia’ from the island of Britain
to the continental mainland?
73
The fact that we cannot be sure about so major an item as cross-Channel
political connections emphasises how little material we have from or about
Brittany in the sixth and seventh centuries. There is some background of
Armoricans ‘in revolt’ against imperial authorities in the fifth century and of
people coming from Britain to settle in the peninsula. There were certainly
enough Britons on the continental mainland by 461 to warrant representation
by their own bishop in the diocese of Tours; and by 567 there were enough
of them in Armorica to be a significant cultural group, distinguished from
the ‘Romans’.
74
Continental writers who died in the last decade of the sixth
century had the habit of calling the peninsula Britannia.
ForGregory of Tours Brittany began at the River Vilaine, the river that
rises well to the east of Rennes, runs through the city and then south to the
coast, 30 kilometres west of the Loire mouth; the Roman civitates of Riedones
and Namnetes, which approximate to the medieval counties of Rennes and
Nantes, and the modern d
´
epartements of Ille-et-Vilaine and Loire Atlantique,
largely lie to the east of that boundary. From Gregory we know quite a lot
about the problems that the Bretons had with the Franks in the 560s, 570s and
580s.
75
The Franks claimed to rule Brittany: they marched into it, and pitched
their tents along the Vilaine; they formally handed the city of Vannes to the
Breton ‘count’ Waroch, in return for an annual tribute; they took hostages
and sureties. The Bretons for their part attacked Rennes and Nantes again and
again, seizing the grape harvest from the Loire vineyards and rushing back to
Brittany with the wine; Waroch kept ‘forgetting’, as Gregory so disarmingly
puts it, the agreements he had made. The interaction was clearly violent and
disruptive. But it was equally clearly limited to quite a small area in south-east
Brittany. Nothing suggests that the Franks ever went to the west, or even the
centre, of Brittany (Gregory speaks of them reaching the Oust, a tributary
of the Vilaine, as if it were some far outpost) and they quite clearly did not
