The Life of Finnian given in the _Salamanca MS._ records many miracles which he performed in Wales. By his prayers and his great faith in God he dried a lake to get a site for a monastery; he caused mountains to overwhelm the invading Saxons; he drove away the serpents, wasps, and birds that afflicted the religious men in the island called Echin, whom he visited in order to derive consolation from their life and doctrine. It is evident, however, from the narrative that he spent most of the thirty years of his sojourn in Britain under the spiritual guidance of Cathmael, and most probably in his great school at Llancarvan. The years being expressed in the manuscript _Lives of the Saints_ by Roman numerals, are always liable to error--the addition of an X will make thirty out of twenty, and a double XX added by the fault of the copyist would make thirty out of ten. It is, however, stated expressly that Finnian having completed the XXXth year of his pilgrimage returned to his native country with Biteus and Genocus and some other religious men of the Britains, who followed the saint on account of the great holiness of his life and conservation. By God's help they landed at Magh Itha in the south of Wexford,[170] at a port called _Dubglais_, whence they proceeded to visit his ancient preceptor, the holy Coemhan, who still dwelt in Dairinis. There was a Dairinis or Oak island in the Blackwater, which was known as Dairinis Molana; but the island here referred to is "Dairinis of Coemhan," as it is called in the _Four Masters_, A.D. 820. It was in Wexford Harbour; and, as we have already seen, Finnian when going to Wales spent some time with Coemhan in that island, so it is only natural that he should return to the scenes of his early years. From Dairinis Finnian went to visit Muiredach Melbrugh, King of Hy Kinselagh at that time, and sought permission to build a church in his territory. The king received Finnian with all honour and reverence, and sent him effective aid in building a church at a place called Achadh Abhail, now Aghold, a parish church in the barony of Shillelagh, county of Wicklow. Leaving some of his monks to continue his work at Aghold, he went himself into the neighbouring district of Hy Bairrche, and spent seven years teaching and preaching at a place called Maonaigh in the saint's Life. It takes its name from the Hy Maonaigh, an influential tribe who possessed that territory, some of whom having migrated to the North settled near the river Erne and gave their name to the co. Monaghan. The are now known as Mooneys.[171] As we are told that Finnian, during his residence in this neighbourhood, sometimes preached before St. Brigid and her nuns, his sojourn there must be fixed before the death of that saint, A.D. 523 or 525. In his great love for holy poverty the saint refused to accept even from St. Brigid a gold ring which she presented to him as a token of her esteem.
