One of the many complaints made by the Irish against the Danes, and particularly of late, is, that by destroying Irish civilization they likewise choked the vigorous germs of a national literature, which, in consequence of the early introduction of Christianity, had begun at a very early period to take root among the Irish people. The existence of a literature, particularly like the ancient Irish, in the vernacular language of the country, must of course always afford a strong proof of a certain degree of education among the people. During the late political agitation in Ireland, the old Irish literature, of which various remains are still preserved, was therefore extravagantly extolled, with the view of proving how glorious and enlightened was the age of Ireland’s long-vanished independence. Whatever opinion may be formed of the remaining relics of this ancient literature, which are mostly limited to chronicles in the form of annals, and a few old songs, it is at all events agreed that they are of very peculiar importance as regards a knowledge of the Norwegian and Danish expeditions. It is true that the Scandinavian Sagas and chronicles contain many accounts of the achievements of the Norwegians in Ireland, both in war and peace; but the Irish records of them are still more copious. The oldest Irish chronicles relate almost as much to the battles of the Norwegians and Danes with the Irish, as to the internal state of Ireland. A singular chronicle in Irish, of the close of the eleventh century, about “the Wars of the Irish and the Northmen,” was discovered a few years ago. It contains not only a complete account of every battle between the Irish and Northmen, down to that of Clontarf, but also various information respecting the settlements of the Norwegians in Ireland, their mode of warfare, weapons, &c. That this chronicle must have been composed not long after the battle of Clontarf, is proved by the fact that it is referred to as an old record in another Irish work, called “The Book of Leinster,” written in the first half of the twelfth century. The above-named ancient chronicle—the publication of which, by that distinguished Irish scholar, Dr. Todd, cannot be far distant—will, in conjunction with the rest of the Irish accounts relative to the Norwegian expeditions into Ireland, afford an excellent opportunity for comparison with the narratives of our Scandinavian Sagas. Meanwhile we have already sufficient information at hand to compare the accounts of the conquerors and the conquered—a method by which the historical truth will evidently come forth more clearly than if we were obliged to adopt exclusively the one-sided statements of either party.
