O'Connor's unsatisfactory translation, published in 1723, and often reprinted, until, in 1811, William Haliday published a good text of the Dionbhrollach, or vindicatory Introduction, and about one-fourth of the Foras feasa, the body of the historical work, with a readable translation, fairly conveying the author's meaning, but vague, and in parts too wide of the original to be useful. This book was never reprinted, and has become very rare. In 1857, John O'Mahony, a competent Irish scholar and native speaker of the language, published, in New York, a faithful translation of the entire work with copious and valuable notes, in a large volume, now also rare. Dr. P. W. Joyce, in 1881, edited, for the use of students, the first part of the Foras feasa, with a close, almost word-forword, translation, and a vocabulary; and I have recently edited the Dionbhrollach for the same purpose. Both these texts, and the first volume of the present edition, fall within the limits of Haliday's publication. I shall not, therefore, until my work is considerably advanced, have actually to break new ground; and, as I do not hesitate to make use of the work of my predecessors, it would be unfair not to admit this, and ungrateful not to acknowledge their assistance. More especially I have to thank Dr. Joyce for the use of his accurate transcript (made some years ago with a view to publication) of part of O'Mulconry's great manuscript of Keating, so highly prized by O'Donovan, Todd, and others, which has greatly helped the present volume. An unpublished Latin translation of Keating exists, by Dr. John Lynch: there is also an English translation much abridged, and rather vague and inaccurate, in manuscript (date about 1700); to this, perhaps, it is that Harris refers in his edition of Ware, and Haliday seems to allude to more than one. These and other very interesting points, on which I have a good deal of information most kindly furnished by friends, I shall refer to more fully in the concluding volume, to which I must also defer my own notes and comment on
