For the various dates assigned to St. Patrick’s death, see Healy, John. _Life and Writings of St Patrick_, pp. 635–7. Bury, J. B. _op. cit._ p. 206 places his death as early as 461 A.D., while the _Annals of the Four Masters_, I., pp. 154–6 give the traditional date as 493 A.D. Modern scholars are inclined to accept one of the earlier dates as the more probable. 2a. Conyngham, D. P., _op. cit._ p. 541. 2b. Unknown. 2c. Power P., _op. cit._ pp. xix–xxii. 3a and 3b. Healy, John, _Ireland’s Saints and Scholars_, p. 114 gives 455 A.D. as the date of foundation, the Four Masters give 457 A.D. I, p. 142. Bury, J. B., places the date of foundation as early as 444 A.D. _op. cit._ p. 154. 3c. See Note 1c above. 4a, 4b, and 4c. Conyngham, D. P., _op. cit._ p. 182.

For this and other monasteries see Article by (Rev.) Laurence P. Murray, _Monasteries of County Louth_, in the _Louth Journal of Archaeology_, I, pp. 22–36. 7a. See Healy’s account of this school, _op. cit._ 7b. Unknown. 7c. The _Annals of Ulster_, sub anno 526 record St. Ailbe’s death, but see Note 2c above. 8a, 8b, and 8c. Healy, John, _op. cit._ 161. 9a, 9b, and 9c. Healy, John, _op. cit._ p. 132, gives 527 A.D. as the date of foundation. The _Chronicon Scottorum_ gives 510 A.D.; but this is evidently too late, as St. Brigid died in 525 A.D., according to the Chronology in Miss Hull’s _Early Christian Ireland_, introductory pages. St. Conlaeth died in 519 A.D. Conyngham, D. P., _op. cit._ p. 133. The same author places the date of her birth at 453 A.D., so it is fair to assume that the date of the foundation of this school is 487 A.D. and not 467 A.D. 10a, 10b, 10c. Murray, L.

Founded by St. Patrick according to the tradition accepted by Conyngham, _op. cit._ p. 540, and others, but more probably at a later date by St. Comgall, d. 601 A.D. See Reeves’ _Ecc.

This list does not claim to be complete. The above dates agree with those given by the most careful authorities. The four saints whose names are marked (*) are usually called the pre-Patrician Saints. Their chronology is very difficult. Some authorities place them as early as the fourth century and some as late as the sixth. CHAPTER III IRISH MONASTICISM
