(Lived about 415-520.) A poet, chief bishop of Leinster, and founder of two churches. His father, MacDara, was prince of the Hy-Bairrche in the country around Carlow. His mother was sister of Dubhtach, the chief bard and brehon of Erin, the first of Patrick's converts at Tara, and the apostle's lifelong friend. Fiacc was a pupil to his uncle in the bardic profession and soon embraced the Faith. Subsequently, when Patrick came to Leinster, he sojourned at Dubhtach's house in Hy-Kinsellagh and selected Fiacc, on Dubhtach's recommendation, to be consecrated bishop for the converts of Leinster. Fiacc was then a widower; his wife had recently died, leaving him one son named Fiacre. Patrick gave him an alphabet written with his own hand, and Fiacc acquired with marvellous rapidity the learning necessary for the episcopal order. Patrick consecrated him, and in after time appointed him chief bishop of the province. Fiacc founded the church of Domnach-Fiech, east of the Barrow. Dr. Healy identifies its site at Kylebeg. To this church Patrick presented sacred vestments, a bell, the Pauline Epistles and pastoral staff. After many years of austere life in this place, Fiacc was led by angelic command to remove to the west of the Barrow, for there "he would find the place of his resurrection". The legends state that he was directed to build his oratory where he should meet a hind, his refectory where he should find a boar.
