There is no doubt but that many similar passages to these might be found in Irish MSS., if looked for by competent scholars, but these extracts probably are sufficient to prove two things. First, that the celebrated cemetery at Brugh, on the Boyne, six miles west from Drogheda, was the burying-place of the kings of Tara from Crimthann (A.D. 84) till the time of St. Patrick (A.D. 432), and that it was also the burying-place of all those who were concerned--without being killed--in the battles of Moytura. We are not, unfortunately, able to identify the grave of each of these heroes, though it may be because only one has been properly explored, that called New Grange, and that had been rifled before the first modern explorers in the seventeenth century found out the entrance. The Hill of Dowth has only partially been opened. The great cairn of Knowth is untouched, so is the great cairn known as the Tomb of the Dagdha. Excavations alone can prove their absolute identity; but this at least is certain, we have on the banks of the Boyne a group of monuments similar in external appearance at least with those on the two Moytura battle-fields, and the date of the greater number of those at Brugh is certainly subsequent to the Christian era.[230] The second point is not capable of such direct proof, but seems equally clear. It is that the kings of the race of Crimthann immediately succeeded to the kings of the Tuatha de Danann, who fought at Moytura. If, indeed, we could trust the assertion that Crimthann was the first king that was buried at Brugh, we should be obliged to find a place for the Daghda under some pseudonym afterwards, and it is possible that may be the case,[231] but for the present it seems more reasonable to assume that he preceded him at a very short interval. According to the 'Four Masters,' the Tuatha de Danann had been extinct for nearly 2000 years when we find Crimthann marrying a princess of that race, and one of sufficient influence to induce him to adopt what appears literally to have been the family burying-place of the Dagdha for that of himself and his race; and it seems impossible to believe that when this took place it could have been old, or neglected, or deserted. According to the 'Four Masters,' the Firbolgs reigned thirty-seven years only, so that they do not in this case seem to err on the side of exaggeration, and the Tuatha de Danann 196 years. From this, however, we must deduct the twenty years they unnecessarily interpolated between the two battles, and we must take something from the eighty years the Dagdha reigned after he was ninety-one years of age. If we allow, then, a century, it will place the battles of Moytura 20 to 30 B.C., and the arrival of the Firbolgs about the middle of the first century B.C. This, with a small limit of error either way is, I am convinced, pretty nearly the true date of these events.[232]
