From the time of Julius Cæsar the island of Britain had been occupied by the Romans, and in consequence had become partly civilized and Christianized. Upon the fall of the empire, the Roman legions were withdrawn, and the people, left defenseless, became the prey of their own northern barbarians, the Picts and Scots; the drama of Southern Europe and the Goths being re-enacted on a diminished scale. In the fourth century the Britons implored the Angles and Saxons to come and protect them from these savages. Invited as allies, they came as invaders, and remained as conquerors, implanting their habits, speech, and paganism upon the prostrate island. It was the extermination of this exotic paganism which impelled to those deeds of valor recited in the Round Table romances, and which made King Arthur and his knights the theme of poet and minstrel for centuries. But the Saxon had come to stay, and Teuton and Kelt became merged, much as do the lion and lamb, after the former has dined! The Teutonic Saxon may be said to have dined on the Keltic Briton, and remained master of the island until the Normans came, six centuries later, and in turn dominated, and made him bear the yoke of servitude. Nor was this French-speaking Norman French at all, except by adoption; being, in fact, the terrible Northman of two centuries before, on account of whose ravages the noble had intrenched himself in his strong castle, and the wretched serf had in mortal terror sold himself and all that he possessed, for the protection of its solid walls and moat; and thus had been laid the foundations of feudalism. He it was who, with longhair reeking with rancid oil, battle-ax, spear, and iron hook--with which to capture human and other prey--had held France in a state of unspeakable terror for centuries, but who had finally settled down as a respectable French citizen in the sea-board province of Normandy, and in two centuries had made such wonderful improvement in manners, apparel, and speech that the simple Saxon baron stood abashed before the splendid refinements of his conquerors. The origin of this mysterious Northman is unknown; but whatever it was, or whoever he was, he certainly possessed Aryan germs of high potency. So the Saxon had built the solid walls of the racial structure upon a foundation of Britons; and, though with no thought for beauty, had built well, with strong, true structural lines. It was the Norman who finished and decorated the structure, but he did not alter one of these lines; the speech, traits, institutions, and habits of England being at the core Saxon to-day, while there is a decorative surface only of Norman.
