Much or all of this pre-Milesian account of the race must be unhesitatingly set down to the influence of Christianity, and to the invention of early Christian bards who felt a desire to trace their kings back to Japhet.[4] The native unchristianised genealogies all converge in the sons and nephew of Milesius. The legends of their exploits and those of their successors are the real race-heritage of the Gael, unmixed with the fanciful Christian allusions and Hebraic adulterations of the pre-Milesian story, which was the last to be invented.
The genuine and early combination of Irish myth and history centres not on foreign but on Irish soil, in the accounts of the Nemedians, the Firbolg, the Tuatha De Danann, and the early Milesians, accounts which have been handed down to us in short stories and more lengthy sagas, as well as in the bold brief chronicles of the annalists. No doubt the stories of the landing of his race on Irish soil, and the exploits of his first chieftains were familiar in the early days to every Gael. They became, as it were, part and parcel of his own life and being, and were preserved with something approaching a religious veneration. His belief in them entered into his whole political and social system, the holding of his tribe-lands was bound up with it, and a highly-paid and influential class of bardic historians was subsidised with the express purpose of propagating these traditions and maintaining them unaltered.
Everything around him recalled to the early Gael the traditional history of his own past. The two hills of Slieve Luachra in Kerry he called the paps of Dana,[5] and he knew that Dana was the mother of the gods Brian, Iuchar, and Iucharba, the story of whose sufferings, at the hands of Lugh the Long-handed, has in later times so often drawn tears from its auditors. When he beheld the mighty barrows piled upon the banks of the Boyne,[6] he knew that it was over the Dagda--an Irish Jupiter--and over his three sons[7] that they were heaped; and one of these, Angus of the Boyne, was, down to the present century, reverenced as the presiding genius of the spot. The mighty monuments of Knock Áine in Limerick, and Knock Gréine, as well as those of Knowth, Dowth, and New Grange, were all connected with his legendary past. It was Lugh of the Tuatha De Danann, he knew, who had first established the great fair of Tailltin,[8] to which he and his friends went from year to year to meet each other, and contract alliances for their grown children. The great funeral mound, round which the games were held, was sacred to Talti, the foster-mother of Lugh, who had there been buried, and in whose honour the games in which he participated were held upon the day which he called--and still calls, though he has now forgotten why--Lughnasa or Lugh's gathering.[9] His own country he called--and still calls--by the various names of Eire, Fódhla [Fola], and Banba, and they, as he knew, were three queens[10] of the Tuatha De Danann. The Gael of Connacht knew that Moycullen, near Galway, was so named from Uillin, a grandson of the Tuatha De Danann king Nuada; and Loch Corrib from Orbsen, the other name of the sea-god Manannán, slain there by this Uillin, and each of the provinces was studded with such memorials.
