Although many of the ideas set forth in this work may seem new to American readers, yet they are by no means wholly original. Many of them have for many years been successfully advocated in Scandinavian countries, and to some extent, also, in Germany and England. Our aim has not at present been so much to make original investigations, as—that which is far more needed and to the purpose—to give the fruits of the labors performed in the North, and call the attention of the American public earnestly to the wealth stored up in the Eddas and Sagas of Iceland. No one can doubt the correctness of our position in this matter, when he reflects that we now drawing near the close of the _nineteenth_ century, and have not yet had a complete Norse mythology in the English language, while the number of Greek and Roman mythologies is legion. Bayard Taylor said to us, recently, that the Scandinavian languages, in view of their rich literature, in view of the light which this literature throws upon early English history, and in view of the importance of Icelandic in a successful study of English and Anglo-Saxon, ought to be taught in every college in Vinland; and that is the very pith of what we have to say in this preface. We have had excellent aid from Dr. S. H. Carpenter, who combines broad general culture with a thorough knowledge of Old English and Anglo-Saxon. He has read every page of this work, and we hereby thank him for the generous sympathy and advice which he has invariably given us. To President John Bascom we are under obligations for kind words and valuable suggestions. We hereby extend heartfelt thanks to Professor Willard Fiske, of Cornell University, for aid and encouragement; to Mrs. Ole Bull, for free use of her excellent library; and to the poet, H. W. Longfellow, for permitting us to make extracts from his works, and to inscribe this volume to him as the Nestor among American writers on Scandinavian themes. May the persons here named find that this our work, in spite of its faults, advances, somewhat, the interest in the studies of Northern literature in this country. While Mallet’s _Northern Antiquities_ is a very valuable work, we cannot but make known our regrets that Blackwell’s edition of it ever was published. Mr. Blackwell has in many ways injured the cause which he evidently intended to promote. While we, therefore, urge caution in the use of Mallet’s _Northern Antiquities_ by Blackwell, we can with all our heart recommend such writers upon the North as Dasent, Laing, Thorpe, Gosse, Pennock, Boyesen, Marsh, Fiske, the Howitts, Pigott, Lord Dufferin, Maurer, Möbius, Morris, Magnússon, Vigfusson, Hjaltalin, and several others.
