“In the North there is a great ocean, and in this ocean there is a large island called Scandza, out of whose loins our race burst forth like a swarm of bees and spread over Europe.” These were the words the Gothic historian Jordanes put on parchment, inspired by the popular traditions of a Teutonic migration from the North. Historic evidence is lacking to prove or disprove the truth of these words. But they may be applied to the phenomenon which has given its name to the _Viking Age_. The Viking expeditions seem to stand in connection with the great Teutonic migrations, at least to be related to them in nature. The Teutons of the North were not directly affected by the migrations, but at the close of the eighth century the same restlessness and desire of expansion appear to have taken possession of the Northmen as in earlier times of their relatives in more southerly lands. And it was a timely move, for the energy and strength with which these had in their time suffused Europe were dying out. Europe was in need of new blood and iron to wake her from her anæmia and to build up new institutions. The North was freed from a turbulent and lawless element and was brought in closer contact than ever before with the learning and culture of the world. For centuries the Northmen had through their southern kinsmen been in contact with continental culture. But now they came out to see for themselves, to make themselves a place in a wider and richer world, or to bring home from there what they most desired of beauty, riches and culture. They were not delicate as to means. Violence was with them as natural as their freedom of individuality was indispensable. Yet they were to play a most important part in the cultural development of Europe, furnishing her with institutions of imperishable iron and changing the darkness of the Middle Ages into an era of chivalry in spirit and in deeds.
