Attested: Dubglas, one of the battle sites attributed to Arthur by the Historia Brittonum (“Nennius”), written probably in about AD 830, referring to events in about AD 500.
Where: Winterton Beck, in northern Lincolnshire, around SE905172, flowing into the Humber past the much studied Romano-British settlement at Dragonby, and the large deposits of iron ore that supported Scunthorpe steel production until recently. Near Winteringham Haven Roman-era travellers heading north on Ermine Street would have taken a ferry to cross the Humber to Petuaria.
Name origin: Dub- survives in northern English, meaning ‘a deep dark pool in a river or stream’, presumably from PIE *dheub- ‘deep’. Back in Arthur’s day glas was related to Latin glaesum ‘amber’, and referred to the rusty colour of water of water with a high iron content (usually due to human activity) and to its ochre deposits. It did not take on the Celtic meaning of green/blue/grey until centuries later.
Notes: Generations of historians have failed to understand the true regional origin of Arthur’s battles because they insisted on trying to interpret a few place names inappropriately with the aid of later Celtic languages!
