Just as the Celts pushed back the Iberian population of Gaul as far south as Aquitania, and swept round it into Spain, so they crossed the Channel and overran the greater portion of Britain, until the Silures,[1] identified by Tacitus with the Iberians, were left only in those fastnesses which were subsequently a refuge for the Welsh against the English invaders.

The Iberian populatian by that time had been driven as far as they could go to the west, not only in Spain and in Gaul, but also in Britain, and were restricted to those areas in which the ethnologist can trace their blood in the present population. Since that time, however, they must have been profoundly affected by the invasions of the various Germanic tribes, who settled in their land, and forced back upon them the Celtic and Belgic peoples, ever pressing them to the west.
Relation of Iberians to Ligurians and Etruskans.
