The _Martyrology of Donegal_ describes Fintan Corach as "Bishop of Cluain-ferta-Brenainn, and he is in Cluain-eidhnech also." But it is uncertain if Fintan ever went to Clonenagh, and it seems highly probable that he was confounded with one of the other Fintans, who founded and ruled that Church. The fact that he was a connection of St. Brendan by the mother's side, will explain why he was chosen to succeed that saint in the government of the Church of Clonfert. It was an established rule to select the comarb from the kin, or failing that, from the tribe of the founder, when a suitable candidate so recommended was forthcoming. No doubt St. Fintan, whilst he governed Clonfert, did much to encourage the study and practice of sacred psalmody in the abbey choir. He could hardly be false to his name, or allow discords to prevail, where harmony--heavenly harmony--should help to raise the mind to God and His Angelic Choirs. He seems to have died towards the end of the sixth century. Archdall gives the date as A.D. 590, but nothing is known for certain on the point. The Abbot Seanach Garbh appears to have been the successor of St. Fintan, but beyond the record of his death, which the _Ulster Annals_ give A.D. 620, we know nothing. St. Colman, son of Comgall, is mentioned by the scholiast of Ængus as the next of the three 'kings' who ruled the abbey in succession to Brendan, but of him in like manner we know nothing more. The next Abbot-Bishop of Clonfert was the celebrated Cummian Fada, or Cummian the Tall, perhaps the most distinguished scholar of his time in Ireland. Before, however, we give an account of his life and writings, it is necessary to refer briefly to another famous disciple of St. Brendan, that is, the celebrated St. Fursey. After Brendan himself, St. Fursey is the most remarkable saint of the times in which he lived, and it is fortunate that we have a Life of this saint still extant which at least in substance must be accepted as authentic. This Life is referred to by Bede, who himself gives a long and most interesting account of the saint. It is evident that the Life quoted by Bede was the work of an almost contemporary writer; for he speaks of the plague and the great eclipse of the sun, which happened _last_ year, that is, as we know from Bede himself, on the 3rd of May, A.D. 664. The Life was therefore written within ten or fifteen years of the death of St. Fursey; and although additions were probably made to it afterwards, it must be accepted even in its present shape as authentic and truthful, at least in substance. It is, moreover, confirmed in many particulars by the evidence of our native annals.
