conversion of Crimthann enabled Iserninus to return to his own land, and he established himself at Aghade, a crossing-place on the Slaney, about nine miles below Rathvilly. Among the acts which are ascribed to Patrick in Leinster, the consecration of Fíacc, the Fair, a pupil of the poet Dubthach, and himself a poet, deserve mention.[158] The conversion of the poet into the Christian bishop reminds us of the more illustrious contemporary case of Sidonius Apollinaris. There seems no reason to doubt the truth of this tradition, and perhaps the bell, the staff, the writing tablet, and the cup and paten, which Patrick is said to have given to Fíacc, were preserved at the church where his memory was specially cherished. He was first settled at a church which was called after himself, Domnach Féicc, the situation of which is not improbably supposed to have been east of the Slaney, not far from Tallow.[159] But he afterwards became bishop of Slébte, on the western bank of the Barrow, under the hills of Margy,[160] and ended his days there. In the early middle ages Slébte was a notable place on the ecclesiastical map, but the desolate site shows no vestiges of its ancient importance. At the end of the seventh century Slébte renewed the ties which bound it to Armagh in the days of Fíacc and Patrick, and we possess a monument of this reconciliation in the earliest biography of Patrick that has come down to us, written by a clerk of Fíacc’s church.[161] § 4. _Church Discipline_ It is not clear whether Auxilius and Iserninus were already invested with episcopal rank when they left Gaul, or were consecrated in Leinster by Patrick.[162] But in any case, they seem, along with Secundinus, who came with them from Gaul, to have held an exceptional position of weight as counsellors and coadjutors. Coming, perhaps, from the episcopal city where Patrick himself had been trained, they corroborated the Gallic influence, we might say the influence of Auxerre, which presided at the organisation of the Church in Ireland. It was natural that Patrick should take special counsel with these men for laying down rules of ecclesiastical discipline, and, on the occasion, perhaps, of one of his visits to Leinster, a body of rules was drawn up in the form of a circular letter, addressed by Patrick, Auxilius, and Iserninus to all the clergy of Ireland.[163] The miscellaneous regulations are arranged in a haphazard manner, and were evidently prompted by abuses or practical difficulties which had come to the notice of the framers. Most of the rules deal with the discipline of the clergy. They testify to such irregularities as a bishop interfering in his neighbour’s diocese; vagabond clerks going from place to place; churches founded without the permission of the bishop. It is ordained that no cleric from Britain shall minister in Ireland, unless he has brought a letter from his superior. All the clergy, from the priest to the doorkeeper, are to wear
