After bringing home these poems of Southern Europe, the Scandinavians proceeded to adapt them to their own use, giving them a new force and beauty. The marvellous in Southern poetry became with them something fraught with deeper meaning; and the Northern version of the Nibelungen-lied acquired an ascendency in its strength and poetical beauty, over the German heroic. Hence, during the Middle Ages, the Scandinavians in general, and Icelanders in particular, came to possess a peculiar chivalrous poetry of their own. It was, however, destined to share the same fate as the great poems of the rest of Europe; first to be reduced to prose romance, and then broken up into ballads. The chief cause of this breaking up of the old order of poetry was due to the Reformation. The national poetry was left to be carried on by the common people alone, and of course in their hands was corrupted and mutilated. Scott speaks of this in his Lay of the Last Minstrel, where he describes the old bard, who "'Tuned to please a peasant's ear The harp a King had loved to hear." These Bards, or Scalds, meaning Smoothers of Language, were welcome guests in the early ages, at the Courts of Kings and Princes. Up to the twelfth century, when the Monks and the art of writing, put an end to their profession, these poets continued to come from Iceland and travel all over the world. In return for their songs they received rings and jewels of more or less value; but never money. We have a list of 230 Scalds who made a name for themselves from the time of Dagnar Lodbrok to that of Vladimir II, or from the end of the eighth to the beginning of the thirteenth century. When Christianity entered Scandinavia the spirit of the old tradition still remained with the people, and became their literature under the name of "Folk Sagas," or as we would call them, fairy tales. These legends are found not only in modern Scandinavia, but they have made their way into all the literature of Europe. Jack the Giant Killer, Cinderella, Blue Beard, the Little Old Woman Cut Shorter, and the Giant who smelled the blood of an Englishman (the Fee, Fi, Fo, Fum of our nursery days), were all heroes and heroines of Scandinavian songs, later adapted in various ways to the use of different countries. After awhile this lost art revived in the Romances of chivalry, and in popular ballads. They describe all the changes in life and society, and are akin to the ballads of the British Isles. In them we find the common expression of the life and feelings of a common race. The same stories often influenced the bards of all countries at different periods. These ballads are all written in the same form and express a certain poetic feeling which is not found in the Epic Age. In all countries they had a refrain, or chorus, which marks the migration of poetry from the Epic to the Lyric form.
