The battles fought by the king of Sorca, aided by Finn and his Fena, against the King of the World, are described at much length in the original; but I have cut them down to a very short compass; and I have omitted altogether a long episode towards the end, which travels away from the main story. This tale has never been translated till now. I translated it chiefly from the Royal Irish Academy MS., 24. B. 28, a well-written manuscript, which was copied out by Edmond Terry, in 1728: but I kept another good copy beside me for comparison, viz., that contained in the Royal Irish Academy MS., 23. G. 21, written in 1795, by Michael Oge O'Longan of Cork, father of Mr. Joseph O'Longan, now the Irish scribe in the Royal Irish Academy, and the transcriber in fac-simile of "Leabhar na h-Uidhre," "Leabhar Breac," and "Leabhar Laighneach." THE PURSUIT OF DERMAT AND GRANIA. This tale is one of those mentioned in the list contained in the Book of Leinster, which was written about A.D. 1130 (see note, page iv.); but though this proves the tale to be an ancient one, I have never come across a copy older than the last century. "The Pursuit of Dermat and Grania" has been published, with text and a very racy idiomatic literal translation, by Mr. Standish Hayes O'Grady, in the Transactions of the Ossianic Society for 1855, from a comparison of two manuscripts, one of 1780 and the other of 1842. In addition to Mr. O'Grady's published text, I made use of another good copy (MS. Royal Irish Academy, 23. G. 21) written in 1795, by Michael Oge O'Longan, already spoken of. I cannot help believing that this fine story originally ended with the death of Dermat; though in all the current versions (including Mr. O'Grady's printed text) there is an additional part recounting the further proceedings of Grania and her sons, after the death of the hero. But this part is in every respect inferior to the rest--in language, in feeling, and in play of imagination. It seems to me very clear that it was patched on to the original story by some unskilful hand; and I have accordingly omitted it, and ended the story with the death of Dermat. I have also omitted two short episodes--that of the _cnumh_ or reptile of Corca Divna, as a mere excrescence; and Finn's expedition to Scotland for aid against Dermat. And, for the sake of clearness, I have slightly changed the place of that part of the tale which recounts the origin of the Fairy Quicken Tree of Dooros. There are one or two other trifling but very necessary modifications, which need not be mentioned here. THE CHASE OF SLIEVE CULLINN: THE CHASE OF SLIEVE FUAD: OISIN IN TIRNANOGE.
