But the Teutons might have done it a hundred years before that, when Rome was in a death agony, and Vitellius and Vespasian were struggling for the purple, and Civilis and the fair Velleda, like Barak and Deborah of old, raised the Teuton tribes. They might have done it before that again, when Hermann slew Varus and his legions in the Teutoburger Wald; or before that again, when the Kempers and Teutons burst over the Alps, to madden themselves with the fatal wines of the rich south. And why did the Teutons _not_ do it? Because they were boys fighting against cunning men. Boiorich, the young Kemper, riding down to Marius' camp, to bid him fix the place and time of battle--for the Teuton thought it mean to use surprises and stratagems, or to conquer save in fair and open fight--is the type of the Teuton hero; and one which had no chance in a struggle with the cool, false, politic Roman, grown grey in the experience of the forum and of the camp, and still as physically brave as his young enemy. Because, too, there was no unity among them; no feeling that they were brethren of one blood. Had the Teuton tribes, at any one of the great crises I have mentioned, and at many a crisis afterwards, united for but three years, under the feeling of a common blood, language, interest, destiny, Rome would have perished. But they could not learn that lesson. They could not put aside their boyish quarrels. They never learnt the lesson till after their final victory, when the Gospel of Christ--of a Being to whom they all owed equal allegiance, in whose sight they were all morally equal--came to unite them into a Christendom. And it was well that they did not learn it sooner. Well for them and for the world, that they did not unite on any false ground of interest or ambition, but had to wait for the true ground of unity, the knowledge of the God-man, King of all nations upon earth. Had they destroyed Rome sooner, what would not they have lost? What would not the world have lost? Christianity would have been stifled in its very cradle; and with Christianity all chance--be sure of it--of their own progress. Roman law, order, and discipline, the very things which they needed to acquire by a contact of five hundred years, would have been swept away. All classic literature and classic art, which they learnt to admire with an almost superstitious awe, would have perished likewise. Greek philosophy, the germs of physical science, and all that we owe to the ancients, would have perished; and we should have truly had an invasion of the barbarians, followed by truly dark ages, in which Europe would have had to begin all anew, without the help of the generations which had gone before.
