An Abbot of Lagny, near Paris, d. 16 Jan., about 650. He was the son of Fintan, son of Finloga, prince of South Muster, and Gelgesia, daughter of Aedhfinn, prince of Hy-Briuin in Connaught. He was born probably amongst the Hy-Bruin, and was baptized by St. Brendan the Traveller, his father’s uncle, who then ruled a monastery in the Island of Oirbsen, now called Inisquin in Lough Corrib. He was educated by St. Brendan’smonks, and when of proper age he embraced the religious life in the same monastery under the Abbot St. Meldan, his “soul-friend” ( anam-chura ). His great sanctity was early discerned, and there is a legend that here, through his prayers, twin children of a chieftain related to King Brendinus were raised from the dead. After some years he founded a monastery at Rathmat on the shore of Lough Corrib which Colgan identifies as Killursa, in the deanery of Annadown. Aspirants came in numbers to place themselves under his rule, but he wished to secure also some of his relatives for the new monastery. For this purpose he set out with some monks for Munster, but on coming near his father’s home he was seized with an apparently mortal illness. He fell into a trance from the ninth hour of the day to cock-crow, and while in this state was favoured with the first of the ecstatic visions which have rendered him famous in medieval literature.
