In this poem the same anachronism may be noticed that led Petrie so much astray about the Lia Fail having been in Tara in the tenth century. Muircheartach addresses Donacha as if he were living in Tara, although Tara had been abandoned four hundred years before, and was as waste and as desolate in the time of Donacha as it is to-day; the chief kings of his epoch and for centuries before it, lived usually in Westmeath or in Donegal. That Muircheartach Mac Neill, though a sort of Rory O'More of the tenth century, was a great man can hardly be doubted. He seems to have contemplated the entire overthrow of the pentarchy and the union of all the provinces under one sole king, namely, himself. He could hardly have been ignorant of what had occurred in England in the century previous--how Alfred had broken up the Saxon heptarchy and made himself practically sole king in England. If Muircheartach had succeeded in destroying the wretched system of provincial nationality, and had made the country a political unit, the subsequent history of Ireland would probably be very different from what it has been. But Muircheartach was killed by his old enemies the Danes, the year after he made his famous circuit. They also killed his father, Niall Glundubh, at the battle of Killmoshogue, near Dublin, in the year 917. Here is what the Four Masters say about him under the year 941[11]: "Muircheartach of the Leather Cloaks, Lord of Aileach, the Hector of the west of Europe in his time, was slain at Ardee (in Louth) by Blacaire, the son of Godfrey, Lord of the Foreigners, on the 26th of March. In lamentation of him it was said-- "'Vengeance and destruction Have descended on the race of Conn for ever; As Muircheartach does not live, alas! The country of the Gael will always be an orphan.'" "ROYAL AND SAINTLY CASHEL" The situation of three of the most historic and remarkable ecclesiastical establishments in Ireland, namely, Clonmacnois, Glendaloch, and Cashel, is very peculiar. The first is on a barren sandhill surrounded by the most strange and unique scenery in Ireland, consisting of almost illimitable meadows interspersed with bogs. The second is in one of the gloomiest and weirdest glens in the island; but Cashel is on a towering rock amid some of the richest land, not only in Ireland but in the world, and overlooking as goodly a country as human eye perhaps ever gazed on. Ancient Irish monks and churchmen must have been peculiarly gifted with an appreciation of the strange, unique, and beautiful in nature, or they would not have fixed their retreats in such peculiar places. If ancient Irish kings loved to place their strongholds on hills such as Tara, Aileach, Knock Aillinn, and Uisneach, ancient Irish ecclesiastics seemed not to have cared whether their churches were on hills or in hollows, provided they were somewhere that was strange, weird, or beautiful.
