an Irish saint, commemorated Nov. 13, was the son of Niatach of the race of Conmac, and brother of St. Diermitius, abbot of Inis Clotra. He is said to have been brought up with his relation St. Jarlath, under St. Benen of Armagh, and to have been a disciple of St. Columba. These statements are evidently inconsistent, and the latter seems the most likely, especially as in the Life of St. Maedhog (or Modicus) of Ferns, born A.D. 558, Maedhog is said to have been his school pupil. He is one of the chief saints of Ireland, and presided over the Church at Fiodnacha, in Magh-Rein, County Leitrim, and his monastery became a famous school of divinity.
