136. The establishment of the Britons in Gaul is proved in
the sixth century by Procopius [Bell. Goth. iv. 20], Gregory
of Tours, the second council of Tours (A.D. 567), and the
least suspicious of their chronicles and lives of saints.
The subscription of a bishop of the Britons to the first
council of Tours (A.D. 461, or rather 481), the army of
Riothamus, and the loose declamation of Gildas (alii
transmarinas petebant regiones, c. 25, p. 8), may
countenance an emigration as early as the middle of the
fifth century. Beyond that era the Britons of Armorica can
be found only in romance; and I am surprised that Mr.
Whitaker (Genuine History of the Britons, p. 214-221) should
so faithfully transcribe the gross ignorance of Carte, whose
venial errors he has so rigorously chastised.
