Thirdly, the Gauls, who on the continent had both that name and the name of the older Celts[12], and must be regarded as the dominant sub-division of their race, impelled in their turn by pressure from the south and east, came over into these islands, and here were called Britons[13]. They squeezed out the earlier occupants from most part of the larger island, driving them north and west and south-west, as the Celtic inhabitants long before had driven the earlier race. When the Romans came, fifty years before Christ, these Britons occupied the land practically from the south coast to the further side of the Firth of Forth. There had been for some time before Caesar's arrival a steady inflow of Belgic Gauls, people from the eastward parts of what we call France; and these people, the most recent comers among the Britons, were found chiefly on the coasts, but in parts had extended to considerable distances inland. The Celts, to distinguish the preceding immigrants by that name, though in fact it does not properly convey the distinction, occupied Devon and Cornwall, South Wales, the north-west corner of North Wales, Cumberland, and the south-west of what we now call Scotland, that is, Wigton, Kirkcudbright, Dumfries, and part of Ayr. They occupied also a belt of Caledonia north of Stirling. They occupied at least the eastern parts of Ireland. Anglesey and Man were in their hands. The parts of Scotland north of Perthshire and Forfar may be regarded as the principal refuge of the remnant of the people whom we have described as the earlier race, before the Celts; and there were traces of them left in almost all the parts occupied by their immediate successors the Celts. The name by which we ought probably to call these latter, the Celts, in whatever part of the islands they might be, has been familiarly used in a sense so limited that it might cause confusion to use it now in its larger sense. I mean Gael, and Gaelic.
Now we gather from the records that before the Jutes and the Angles and the Saxons came, and in their turn drove the Britons north and west, the religion of Christ had spread to all parts of the territory occupied by the Britons, that is, to the towns in all parts. It may very well have been that in the country parts there were many pagans left even to the last, perhaps in towns too. Putting the commencement of the driving out of the Britons at about the year 450 after Christ, we know that less than a hundred years before that time the pagans were so numerous in Gaul, that when Martin became Bishop of Tours, the pagans were everywhere, and to work for their conversion would have been sufficient work for him. As for the towns in Gaul, Hilary, the Bishop of Poitiers, was a leading official in that town, and only became a Christian in the year 350, when he was about thirty-five years of age. Martin of Tours, too, was born a heathen. We may be sure that in Britain, so remote from the centres of influence, and so inaccessible by reason of its insular position, that state of things continued to prevail a good deal longer than in the civilised parts of Gaul. We must not credit our British predecessors with anything like a universal knowledge and acceptance of Christianity.
