In the battle of Gabra, fought in the third century, and in which Oscar, perhaps the greatest of all the Irish heroes heading the Fianna Eireen, contended against Cairbry of the Liffey, King of Ireland, and his troops, Cairbry on his side announces to his warriors that he would rather perish in this battle than suffer one of the Fianna to survive; but while he spoke—

"Barran suddenly exclaimed—
'Remember Mall Mucreema, remember Art.
"'Our ancestors fell there
By force of the treachery of the Fians;
Remember the hard tributes,
Remember the extraordinary pride.'"

Here the poet, singing only of the events of the battle of Gabra, shows that he was well-acquainted with all the relations subsisting for a long time between the Fians and the Royal family. The battle of Mucreema was fought by Cairbry's grandfather, Art, against Lewy Mac Conn and the Fianna Eireen.

Again, in the tale of the battle of Moy Leana, in which Conn of the Hundred Battles, the father of this same Art, is the principal character, the author of the tale mentions many times circumstances relating to his father, Felimy Rectmar, and his grandfather, Tuhall Tectmar. Such is the whole of the Irish literature, not vague, nebulous, and shifting, but following the course of the fasti, and regulated and determined by them. This argument has been used by Mr. Gladstone with great confidence, in order to show the substantial historical truthfulness of the Iliad, and that it is in fact a portion of a continuous historic sequence.

Now this being admitted, that the course of Irish history, as laid down by the chroniclers, was familiar to the authors of the tales and heroic ballads, one of two things must be admitted, either that the events and kings did succeed one another in the order mentioned by the chroniclers, or that what the chroniclers laid down was then taken as the theme of song by the bards, and illuminated and adorned according to their wont.

The second of these suppositions is one which I think few will adopt. Can we believe it possible that the bards, who actually supported themselves by the amount of pleasure which they gave their audiences, would have forsaken those subjects which were already popular, and those kings and heroes whose splendour and achievements must have affected, profoundly, the popular imagination, in order to invent stories to illuminate fabricated names. The thing is quite impossible. A practice which we can trace to the edge of that period whose historical character may be proved to demonstration, we may conclude to have extended on into the period immediately preceding that. When bards illuminated with stories and marvellous circumstances the battle of Clontarf and the battle of Moyrath, we may believe their predecessors to have done the same for the earlier centuries. The absence of an imaginative literature other than historical shows also that the literature must have followed, regularly, the course of the history, and was not an archaeological attempt to create an interest in names and events which were found in the chronicles. It is, therefore, a reasonable conclusion that the bardic literature, where it reveals a clear sequence in the order of events, and where there is no antecedent improbability, supplies a trustworthy guide to the general course of our history.

So far as the clear light of history reaches, so far may these tales be proved to be historical. It is, therefore, reasonable to suppose that the same consonance between them and the actual course of events which subsisted during the period which lies in clear light, marked also that other preceding period of which the light is no longer dry.

The earliest manuscript of these tales is the Leabhar [Note: Leabar na Heera.] na Huidhré, a work of the eleventh century, so that we may feel sure that we have them in a condition unimpaired by the revival of learning, or any archaeological restoration or improvement. Now, of some of these there have been preserved copies in other later MSS., which differ very little from the copies preserved in the Leabhar na Huidhré, from which we may conclude that these tales had arrived at a fixed state, and a point at which it was considered wrong to interfere with the text.

The feast of Bricrind is one of the tales preserved in this manuscript. The author of the tale in its present form, whenever he lived, composed it, having before him original books which he collated, using his judgment at times upon the materials to his hand. At one stage he observes that the books are at variance on a certain point, namely, that at which Cuculain, Conal the Victorious, and Laery Buada go to the lake of Uath in order to be judged by him. Some of the books, according to the author, stated that on this occasion the two latter behaved unfairly, but he agreed with those books which did not state this.

We have, therefore, a tale penned in the eleventh century, composed at some time prior to this, and itself collected, not from oral tradition, but from books. These considerations would, therefore, render it extremely probable that the tales of the Ultonian period, with which the Leabhar na Huidhré is principally concerned, were committed to writing at a very early period.
