In this story I have been obliged to make a few transpositions in the mere order of the incidents, for the narrative in the original is in some places very ill arranged. It is now nearly eight hundred years since this story was _transcribed_ from some old authority into "The Book of the Dun Cow;" and it is singular that the tradition of the formation of Lough Neagh, by the overflow of an enchanted well which was neglected by the woman in charge of it, still maintains a vivid existence among the peasantry. (See on this subject the author's "Origin and History of Irish Names of Places," Series I. 4th edition, page 176.) CONNLA OF THE GOLDEN HAIR, AND THE FAIRY MAIDEN. This tale (called in the original "Echtra Condla Cain," "The Adventures of Connla the Comely") is taken from "The Book of the Dun Cow." It has been published, with text and literal translation, by the late J. O'Beirne Crowe, in the Kilkenny Archæological Journal (volume 1874-5, page 128). This is one of the many tales that illustrate the ancient and widespread superstition that fairies sometimes take away mortals to their palaces in the fairy forts and pleasant green hills;[19] of which the last story in this book--"Oisin in Tirnanoge"--is another example. This superstition prevailed in Ireland and the Scottish Highlands as far back as either history or tradition reaches; it flourished in full vigour within my own memory; and it is scarcely quite extinct--in Ireland at least--at the present day.[VI.] In connection with the antiquity of this superstition, it must be borne in mind that the present story was transcribed into "The Book of the Dun Cow" in or about the year 1100, from some older book; and that it relates to the time of Conn the Hundred-fighter, king of Ireland, who reigned in the second century of the Christian era. THE VOYAGE OF MAILDUN. Of this tale (which is now given to the public for the first time) the oldest copy is in "The Book of the Dun Cow" (about the year 1100); but it is imperfect at both beginning and end--a portion having been torn away when the book was mutilated at some former time. There is a perfect copy in the Yellow Book of Lecan, in Trinity College, Dublin, and another in the British Museum (MS. Harl. 5280). After I had made a rough translation of the greater part of this piece, I discovered a good literal translation in manuscript in the Royal Irish Academy, made by the late J. O'Beirne Crowe, which was of great use to me, as it helped to explain some strange terms, and to clear up some obscure passages. This voyage would appear from internal evidence to have been made in the beginning of the eighth century (O'Curry says about the year 700); for I think it likely that Maildun did actually go on a voyage, which was afterwards made the framework of the story. On my translation of this tale, Lord Tennyson founded his poem "The Voyage of Maeldune."
