Late Romans mostly Celt?

[ambrosius]

I give up I say...Celts are the real (late)Romans.

Agree with you, there, bro'! 8)

In as much as Gaul, Spain and Britain had been thoroughly Romanized
by the 5th c. then, absolutely, the native Celtic populations had become
the real late-Romans. Modern historians call 5th c. natives of Gaul
'Gallo-Romans', and the invading Anglo-Saxons called the native
population of 5th c. Britain (often claimed to be exclusively 'Celtic' by
many - which ignores all their recent Roman cultural assimilations)
'Wealas', which has the connotation of 'Romanized people'. :wink:
