That Snorri really wrote the work as here described seems to be undoubted, although there is no trace of it as a whole until after his death. At what period of his career it arose, can however merely be conjectured. We only know with certainty the date of the 'Hattatal'; that may not unlikely have been the nucleus of the whole, which falls undoubtedly between 1221 and 1223, shortly after the return from the first visit to Norway. The oldest manuscript of the 'Snorra Edda,'--now in the University Library at Upsala, Sweden,--which was written before 1300, assigns the work to him by name; and the 'Icelandic Annals,' as has already been stated, under the year of his death corroborate the statement of his authorship of "the Edda"--that is, of course, of this particular 'Edda,' for there can be no thought of the other. Snorri's poetical work outside of the 'Edda' is represented only by fugitive verses. An encomium that he wrote on the wife of Earl Hakon has been lost. As a poet, Snorri undoubtedly stands upon a lower plane than that which he occupies as a historian. He wrote at a time when poetry was in its decline in Iceland; and neither in the 'Hattatal' nor in his other verse, except in form and phraseology, of which he had a wonderful control, does he rise to the level of a host of earlier skalds. It is his critical knowledge of the old poetry of Norway and Iceland that makes his 'Edda' of such unique value, and particularly as no small part of the material accessible to him has since been irrevocably lost. Snorri's 'Edda,' in its very conception, is a wonderful book to have arisen at the time in which it was written, and in no other part of the Germanic North in the thirteenth century had such a thing been possible. It is not only, however, as a commentary on old Norse poetry that it is remarkable. Its importance as a compendium of the ancient Northern mythology is as great,--one whose loss nothing could supplant. As a whole, it is of incalculable value to the entire Germanic race for the light that it sheds upon its early intellectual life, its ethics, and its religion. The history of the 'Elder Edda' does not go back of the middle of the seventeenth century. In 1643 the Icelandic bishop Brynjolf Sveinsson sent as a present to Frederick III. of Denmark several old Icelandic vellums, among which was the manuscript, dating, according to the most general assignment, from not earlier than 1350; since called the 'Codex Regius' of the 'Edda.' Not a word is known about its previous history. As to when it came into the hands of the bishop, or where it was discovered, he has given us no clew whatsoever. He had nevertheless not only a name ready for it, but a distinct theory of its authorship, for he wrote on the back of a copy that he had made, "Edda Saemundi Multiscii" (the Edda of Saemund the Wise).
