tribes, and prepared the way for that of the kingdoms. In the midst of this work of construction, so incomplete as yet, but so full of hope, of these birthpangs of a new life, the very existence of the country was threatened by the rise of a new Great Power. For so may we well designate the influence which the Scandinavian North exercised by land over Eastern Europe, and at the same time over all the Western coasts by sea. Only a part of the German peoples had been influenced by the idea of the Empire or the Church; the inborn heathenism of the rest, irritated by the losses it had sustained and the dangers that continually threatened it, roused itself for the most formidable onslaught that the civilised world has ever had to withstand from the heroic and barbarous children of Nature. The mischief they wrought in Britain, from the middle of the ninth century onwards, is indescribable. The Scoto-Irish schools, then in their most flourishing state (they trained John Scotus Erigena, of all the scholars of that time the man who had the widest intellectual range), fell before the Danish, not the Anglo-Saxon assaults; an element of intellectual activity which might have been of the greatest importance was thus lost to the Western world. But the Northmen persecuted the Romano-English forms as bitterly as they did the Irish. In the places where those Anglo-Saxon scholars had been trained, who then enlightened the West, the Northmen planted the banner which announced utter destruction; with twofold rapacity they threw themselves on the more remote abbeys which seemed to derive protection from their inaccessibility, and to guarantee it by their dignity; in searching for the treasures which they believed had been placed in them for security, they destroyed the monuments and means of instruction which were really there; in Medeshamstede, where there was a rich library, the flames raged for fourteen days. The half-formed union of the various districts into one kingdom seems to have crippled rather than strengthened the power of local resistance: the Danes became masters of Kent and of East-Anglia, of Northumberland, and even of Mercia; at last Wessex too, after already suffering many losses, was invaded; from both sides at the same moment, from the inland and from the coast, the deluge of robber-hordes poured over its whole extent.
