Note 7 — Chapter IX

In O'Donovan's fragmentary manuscript catalogue of the Irish MSS., in Trinity College, Dublin, he writes apropos of the life of St. Maedhog or Mogue, contained in H. 2, 6: "I searched the two Brefneys for the situation of Moy Sleacht on which stood the chief pagan Irish idol Crom Cruach, but have failed, being misled by Lanigan, who had been misled by Seward, who had been blinded by the impostor Beauford, who placed this plain in the county of Leitrim. It can, however, be proved from this life of St. Mogue that Magh Sleacht was that level part of the Barony of Tullaghan (in the county of Cavan) in which the island of Inis Breaghwee (now Mogue's Island), the church of Templeport, and the little village of Ballymagauran are situated." I have been told that O'Donovan afterwards found reason to doubt the correctness of this identification.
