If this is so, there is little difficulty in determining who were buried here. Besides the testimony of the poem just quoted, it is stated in the Book of the 'Cemeteries'--"At Tailten the kings of Ulster were used to bury vig^t. Ollamh Fodhla with his descendants down to Conchobhar, who wished to be carried to a place between Slea and the sea, with his face to the east, on account of the faith which he had embraced." This conversion of Conchobhar is one of the most famous legends in Irish ancient history. He was wounded in the head by a ball that remained there, and was ordered by his physician to remain quiet and avoid all excitement as his only chance of surviving. For seven years he followed this advice; but when he saw the eclipse of the sun, and felt the great convulsion that came over nature, the day that Christ was crucified, he turned to his Druid and asked, "What is this?" To which Bacrach, the Druid, replied: "It is true, indeed, Christ, the Son of God, is this day crucified by the Jews." "At the recital of this enormity, Conchobhar felt so indignant that he went nearly mad: his excitement was so great that the ball burst from his head, and he died on the very Friday on which the crucifixion took place."[254] All this may be silly enough, as the electric telegraph was not then in use, but it is worth quoting here, as it seems that it was to establish this synchronism that the chronology of the period was falsified to the extent of half a century at least. Conchobhar and Crimthann were the two kings of the two great dynasties then reigning in Ireland whom the annalists strive to synchronize with Christ, and though they fail in that, they establish beyond much doubt that those kings were contemporaries. If to this we add the fact so often repeated by the authorities quoted above, that Conchobhar was the last of his race buried at Talten, and that Crimthann was the first of his line buried at Brugh, we obtain a tolerably clear idea of the history of these cemeteries. Brugh, in fact, succeeded to Talten on the decline of the Ultonian dynasty and the rise of Tuatha de Danann after the victories at Moytura had established their supremacy and they had settled themselves at Tara.
