[Son of Crimthain.] HE was a native of Leinster in Ireland, a disciple of St. Finian, and became a great master of a spiritual life. He founded and governed the monastery of Tyrdaglas, in Munster, and died of a pestilence which raged in Ireland in the year 548.
ST. CORMAC, an ancient Irish saint, is mentioned in the Calendars on this day, as an abbot of eminent sanctity. Usher supposes him the same who paid a visit to St. Columkille, mentioned by Adamnan, l. 3, c. 117.
