Still the schools were not entirely destroyed, for in A.D. 868 is recorded the death of Cormac--Steward, Scribe, and Doctor of Clonfert-Brenainn. It was well that God then called him away, for next year, in A.D. 869, came Earl Tomrar with his warriors from Limerick to Clonfert. "He was a fierce, cruel, rough man of the Lochlans;" and hoped to obtain a great prey in the church and monastery. But he was disappointed, for the brethren heard of his approach, and fled expertly before him, as the Annals tell us, some in boats, and some into the surrounding morasses. Others took refuge in the church, but the disappointed freebooter killed them all, both those whom he found in the church and in the cemetery. Tomrar, however, died of madness three days afterwards, "for Brendan wrought a miracle upon him for plundering his monastery and killing his monks." In A.D. 949, Ceallachan, King of Cashel, plundered the monastery of Clonfert. But the men of Munster were not without rivals in their deeds of sacrilege. In A.D. 1031 Art O'Rorke, surnamed the 'Cock,' plundered the monastery once more, but providentially when returning laden with his pillage, he fell in with Doncha, son of Brian, who defeated him and his followers with great slaughter. Some thirty years later in A.D. 1065, Aedh O'Rorke and Diarmaid O'Kelly plundered Clonfert and Clonmacnoise, and once more speedy vengeance overtook the robbers; for Aedh O'Connor came against them and defeated them through the miracles of Ciaran and Brenainn, whose churches they had plundered. A bloody slaughter was made by Aedh, and, moreover, he captured or sunk their boats, and drove great numbers of the plunderers into the river. Yet the monastery and School of Clonfert still lived on down to the advent of the Anglo-Normans, for in the year A.D. 1170, is recorded the death of Cormac O'Lumluini, whom the Four Masters in pathetic language describe as the remnant of the Sages of Erin. The subsequent history of the School and See of Clonfert is foreign to our present purpose. The old Cathedral of Clonfert still survives, and is one of the few of our ancient buildings now used for religious worship. It has passed, however, from Catholic hands, and will, doubtless, soon be abandoned by the Protestants too, for the few persons who attend divine worship in the old Cathedral of St. Brendan can hardly be called a congregation.
