[Called also Aidan and Mogue.] He was born in Connaught, a province of Ireland, and seemed from his infancy to be deeply impressed with the fear of God. He passed in his early days into Wales, where he lived for a considerable time under the direction of the holy abbot David. He returned afterwards to his own country, accompanied with several monks of eminent piety, founded a great number of churches and monasteries, and was made bishop of Ferns. He died in 632, according to Usher. His name is celebrated among the Irish saints. It appears from Cambrensis that his festival was observed in Wales in the twelfth century. He was also honoured in Scotland.
