Britain was directly Roman for fully four hundred years; longer than she has been Protestant, and very much longer than she has been industrial. What was meant by being Roman it is necessary in a few lines to say, or no sense can be made of what happened after, especially of what happened immediately after. Being Roman did _not_ mean being subject, in the sense that one savage tribe will enslave another, or in the sense that the cynical politicians of recent times watched with a horrible hopefulness for the evanescence of the Irish. Both conquerors and conquered were heathen, and both had the institutions which seem to us to give an inhumanity to heathenism: the triumph, the slave-market, the lack of all the sensitive nationalism of modern history. But the Roman Empire did not destroy nations; if anything, it created them. Britons were not originally proud of being Britons; but they were proud of being Romans. The Roman steel was at least as much a magnet as a sword. In truth it was rather a round mirror of steel, in which every people came to see itself. For Rome as Rome the very smallness of the civic origin was a warrant for the largeness of the civic experiment. Rome itself obviously could not rule the world, any more than Rutland. I mean it could not rule the other races as the Spartans ruled the Helots or the Americans ruled the negroes. A machine so huge had to be human; it had to have a handle that fitted any man's hand. The Roman Empire necessarily became less Roman as it became more of an Empire; until not very long after Rome gave conquerors to Britain, Britain was giving emperors to Rome. Out of Britain, as the Britons boasted, came at length the great Empress Helena, who was the mother of Constantine. And it was Constantine, as all men know, who first nailed up that proclamation which all after generations have in truth been struggling either to protect or to tear down.
