into High German and circulated at South German courts about 1170, and then received its present courtly form about 1190, this last version being the immediate source of our manuscripts.
The story of Siegfried, his tragic death, and the dire vengeance visited upon his slayers, which lies at the basis of our poem, antedates the latter by many centuries, and was known to all nations whose languages prove by their resemblance to the German tongue their original identity with the German people. Not only along the banks of the Rhine and the Danube and upon the upland plains of Southern Germany, but also along the rocky fjords of Norway, among the Angles and Saxons in their new home across the channel, even in the distant Shetland Islands and on the snow-covered wastes of Iceland, this story was told around the fires at night and sung to the harp in the banqueting halls of kings and nobles, each people and each generation telling it in its own fashion and adding new elements of its own invention. This great geographical distribution of the legend, and the variety of forms in which it appears, make it difficult to know where we must seek its origin. The northern version is in many respects older and simpler in form than the German, but still it is probable that Norway was not the home of the saga, but that it took its rise in Germany along the banks of the Rhine among the ancient tribe of the Franks, as is shown by the many geographical names that are reminiscent of the characters of the story, such as a Siegfried "spring" in the Odenwald, a Hagen "well" at Lorsch, a Brunhild "bed" near Frankfort, and the well-known "Drachenfels", or Dragon's Rock, on the Rhine. It is to Norway, however, that we must go for our knowledge of the story, for, singularly enough, with the exception of the "Nibelungenlied" and the popular ballad, German literature has preserved almost no trace of the legend, and such as exist are too late and too corrupt to be of much use in determining the original features of the story.
Just when the legend emigrated to Skandinavia we do not know, but certainly at an early date, perhaps during the opening years of the sixth century. It may have been introduced by German traders, by slaves captured by the Northmen on their frequent marauding expeditions, or, as Mogk believes, may have been taken by the Heruli on their return to Norway after their defeat by the Langobardi. By whatever channel, however, the story reached the North, it became part and parcel of Skandinavian folklore, only certain names still pointing to the original home of the legend. In the ninth century, when Harald Harfagr changed the ancient free constitution of the land, many Norwegians emigrated to Iceland, taking with them these acquired legends, which were better preserved in this remote island because of the peaceful introduction of Christianity, than on the Continent, where the Church was more antagonistic to the customs and legends of the heathen period.
