Professor Rhys also puts forward evidence to show that the Goidels and the Brythons had already separated before they first left Gaul for our islands.[15] He finds them as two distinct peoples there. We do not expect so much nowadays from “the merest school-boy” as we did in Macaulay’s time, but even the modern descendant of that paragon could probably tell us that all Gaul was divided into three parts, one of which was inhabited by the Belgae, another by the Aquitani, and the third by those who called themselves Celtae, but were termed Galli by the Romans; and that they all differed from one another in language, customs, and laws.[16] Of these, Professor Rhys identifies the Belgae with the Brythons, and the Celtae with the Goidels, the third people, the Aquitani, being non-Celtic and non-Aryan, part of the great Hamitic-speaking Iberian stock.[17] The Celtae, with their Goidelic dialect of Celtic, which survives to-day in the Gaelic languages of Ireland, Scotland, and the Isle of Man, were the first to come over to Britain, pushed forward, probably, by the Belgae, who, Caesar tells us, were the bravest of the Gauls.[18] Here they conquered the native Iberians, driving them out of the fertile parts into the rugged districts of the north and west. Later came the Belgae themselves, compelled by press of population; and they, bringing better weapons and a higher civilization, treated the Goidels as those had treated the Iberians. Thus harried, the Goidels probably combined with the Iberians against what was now the common foe, and became to a large degree amalgamated with them. The result was that during the Roman domination the British Islands were roughly divided with regard to race as follows: The Brythons, or second Celtic race, held all Britain south of the Tweed, with the exception of the extreme west, while the first Celtic race, the Goidelic, had most of Ireland, as well as the Isle of Man, Cumberland, the West Highlands, Cornwall, Devon, and North Wales. North of the Grampians lived the Picts, who were probably more or less Goidelicized Iberians, the aboriginal race also holding out, unmixed, in South Wales and parts of Ireland.
