What exactly took place at the time of the German revolt we shall never know; certain it is, however, that from about the year 300 B.C. onward the Celts appear to have lost whatever political cohesion and common purpose they had possessed. Rent asunder, as it were, by the upthrust of some mighty subterranean force, their tribes rolled down like lava-streams to the south, east, and west of their original home. Some found their way into Northern Greece, where they committed the outrage which so scandalised their former friends and allies in the sack of the shrine of Delphi (273 B.C.). Others renewed, with worse fortune, the old struggle with Rome, and perished in vast numbers at Sentinum (295 B.C.) and Lake Vadimo (283 B.C.). One detachment penetrated into Asia Minor, and founded the Celtic State of Galatia, where, as St. Jerome attests, a Celtic dialect was still spoken in the fourth century A.D. Others enlisted as mercenary troops with Carthage. A tumultuous war of Celts against scattered German tribes, or against other Celts who represented earlier waves of emigration and conquest, went on all over Mid-Europe, Gaul, and Britain. When this settled down Gaul and the British Islands remained practically the sole relics of the Celtic empire, the only countries still under Celtic law and leadership. By the commencement of the Christian era Gaul and Britain had fallen under the yoke of Rome, and their complete Romanisation was only a question of time. *Unique Historical Position of Ireland* Ireland alone was never even visited, much less subjugated, by the Roman legionaries, and maintained its independence against all comers nominally until the close of the twelfth century, but for all practical purposes a good three hundred years longer. Ireland has therefore this unique feature of interest, that it carried an indigenous Celtic civilisation, Celtic institutions, art, and literature, and the oldest surviving form of the Celtic language,(19) right across the chasm which separates the antique from the modern world, the pagan from the Christian world, and on into the full light of modern history and observation. *The Celtic Character* The moral no less than the physical characteristics attributed by classical writers to the Celtic peoples show a remarkable distinctness and consistency. Much of what is said about them might, as we should expect, be said of any primitive and unlettered people, but there remains so much to differentiate them among the races of mankind that if these ancient references to the Celts could be read aloud, without mentioning the name of the race to whom they referred, to any person acquainted with it through modern history alone, he would, I think, without hesitation, name the Celtic peoples as the subject of the description which he had heard.
