It is not at all certain that Siegfried was an historical person. Though there is some reason for thinking that he was Arminius, the fearless leader of the Germans in the terrible revolt by which they overthrew their Roman rulers in the year 9 A. D., yet of the warriors with whom he has been identified, Siegfried seems most like Sigibert, king of the Franks who lived in Austrasia, or ancient Germany. For this king, like Siegfried, overcame the Saxons and Danes by his brave fighting, he too discovered a hidden treasure, and he was at length treacherously put to death by pages of his sister-in-law, Fredegunde, with whom his wife, Brunhilde, had quarreled over some question of precedence. After all, though, it does not make a great difference whether or not Siegfried was any of the heroes to whom he has been likened or was all of them put together; he really lives for us in the wonderful story of his knightly bravery and good faith. Some of the greatest poets and dramatists and composers, not only of Germany, but of other countries as well, have made use of incidents from the Nibelungenlied. Of all these works which have been produced with this old poem as a basis, the Ring of the Nibelungen, a group of four operas by Richard Wagner, is most famous. These operas, which are among the finest works of this great composer, are not based absolutely on the Nibelungenlied; many happenings in the life of the hero, Siegfried, are different. But it is clear that Wagner drew his inspiration from this thirteenth century epic, and his use of it has opened other people's eyes to its beauties. In the golden days of knightly adventure, when heroes famed for marvelous daring went up and down the land in search of deeds in which to display their skill, strength and courage in combat, and their gallantry towards fair ladies, there lived in one of the countries on the Rhine a prince named Siegfried who, though but a youth, was noted far and wide for his unequaled valor and boldness. When he was a mere boy he nobly served his country in putting to death the Dragon of the Linden-tree, a monster so full of hate that it would cast its poison out upon any one who came near it, and so strong that it could destroy any one who tried to conquer it. Nevertheless the fearless Siegfried not only slew this evil creature but bathed in its blood, thus making his own skin so hard that it could never afterward be pierced by any weapon. At another time, while traveling through the land of the Nibelungers, he came upon the two princes of the country and a company of their attendants gathered about the foot of a hill from which had just been taken great quantities of gold and precious stones. [Illustration: SIEGFRIED AND THE DRAGON] "Ho, Siegfried," called one of the princes, advancing to meet him, "come to our aid, for we are much in need of some one to divide between my brother and myself this treasure left us by our father. For such help we will prove to you our gratitude."
