Murtough appears to have been a not unusual compound of piety and profanity. We read in one place of his reckless exploits in burning churches and desecrating shrines, and in others of his liberal endowments of the same.

The Danes had now settled quietly in the mercantile towns which they had mainly contributed to form, and expended all their energies on commerce instead of war; but the new generation of Northmen, who had not yet visited Ireland, could not so easily relinquish the old project of conquering it. About the year 1101, Magnus planned an expedition to effect this purpose. He arrived in Dublin the following year; a "hosting of the men of Ireland came to oppose him;"[[236]] but they made peace with him for one year, and Murtough gave his daughter in marriage to his son Sitric, "with many jewels and gifts." The year 1103 was distinguished for sanguinary conflicts. Murdhadh Drun was killed on a predatory excursion in Magh Cobha. Raghnall Ua h-Ocain,[[237]] lawgiver of Felach Og, was slain by the men of Magh Itha. There was a "great war" between the Cinel-Eoghain and the Ulidians; and Murtough O'Brien, with the men of Munster, Leinster, and Ossory, the chiefs of Connaught, and the men of Meath and their kings, proceeded to Magh Cobha (Donaghmore, co. Down) to relieve the Ulidians. When the men of Munster "were wearied," Murtough proceeded to Ard-Macha, and left eight ounces of gold upon the altar, and promised eightscore cows. The northern Hy-Nials then attacked the camp of the Leinster men, and a spirited battle was fought. The Cinel-Eoghain and Cinel-Connaill returned victoriously and triumphantly to their forts, with valuable jewels and much wealth, together with the royal tent, the standard, and jewels.

Magnus, King of Lochlann and the Isles, was slain by the Ulidians this year.

It is noticeable that, in the Annals of the Four Masters, obituaries of saints or good men always occupy the first place. The Annals of this year are of unusual length; but they commence with the obituary of Murchadh O'Flanaghan, Arrchinneach of Ardbo, a paragon of wisdom and instruction, who died on his pilgrimage at Ard-Macha. A priest of Kildare is also mentioned, and the Tanist-Abbot of Clonmacnois, a prosperous and affluent man.

It would appear that the Irish were sufficiently occupied with domestic wars to prevent their offering assistance elsewhere. This, however, was not the case. When Harold returned to England, his brother-in-law, Donough, lent him nine ships; and we find the Irish affording assistance in several other feuds of the Anglo-Saxons of this period. A deputation of the nobles of Man and other islands visited Dublin, and waited on Murtough O'Brien to solicit a king. He sent his nephew, Donnell; but he was soon expelled on account of his tyranny. Another Donnell O'Brien, his cousin, was, at the same time, lord of the Danes in Dublin. In 1114 Murtough O'Brien was obliged to resign the crown in consequence of ill-health; the Annals say that he became a living skeleton. His brother, Dermod, took advantage of this circumstance to declare himself King of Munster. This obliged Murtough to resume the reins of government, and put himself at the head of his army. He succeeded in making Dermod prisoner, but eventually he was obliged to resign the kingdom to him, and retired into the Monastery of Lismore, where he died in 1119. The Annals call him the prop of the glory and magnificence of the western world. In the same year Nial Mac Lochlann, royal heir of Aileach and of Ireland, fell by the Cinel-Moain, in the twenty-eighth year of his age. He was the "paragon of Ireland, for personal form, sense, hospitality, and learning." The Chief Ollamh of Ireland, Cucollchoille ua Biagheallain, was killed by the men of Lug and Tuatha-ratha (Tooragh, co. Fermanagh), with his wife, "two very good sons," and five-and-thirty persons in one house, on the Saturday before Little Easter. The cause of this outrage is not mentioned. The Annals of the Four Masters and the Annals of Ulster record the same event, and mention that he was distinguished for charity, hospitality, and universal benevolence.

Donnell O'Loughlin died in 1121, in the Monastery of St. Columba, at Derry. He is styled King of Ireland, although the power of his southern rival preponderated during the greater part of his reign. In 1118 Rory O'Connor died in the Monastery of Clonmacnois. He had been blinded some years previously by the O'Flaherties. This cruel custom was sometimes practised to prevent the succession of an obnoxious person, as freedom from every blemish was a sine qua non in Erinn for a candidate to royal honours. Teigue Mac Carthy, King of Desmond, died, "after penance," at Cashel, A.D. 1124. From the time of Murtough O'Brien's illness, Turlough O'Connor, son of the prince who had been blinded, comes prominently forward in Irish history. His object was to exalt the Eoghanists or Desmonian family, who had been virtually excluded from the succession since the time of Brian Boroimhé. In 1116 he plundered Thomond as far as Limerick. In 1118 he led an army as far as Glanmire (co. Cork), and divided Munster, giving Desmond to Mac Carthy, and Thomond to the sons of Dermod O'Brien. He then marched to Dublin, and took hostages from the Danes, releasing Donnell, son of the King of Meath, whom they had in captivity. The following year he sailed down the Shannon with a fleet, and destroyed the royal palace of Kincora, hurling its stones and timber beams into the river. He then devoted himself to wholesale plundering, and expelled his late ally and father-in-law from Meath, ravaging the country from Traigh Li (Tralee) to the sanctuary lands of Lismore. In 1126 he bestowed the kingdom of Dublin on his son Cormac. In 1127 he drove Cormac Mac Carthy from his kingdom, and divided Munster in three parts. In fact, there was such a storm of war throughout the whole country, that St. Celsus was obliged to interfere. He spent a month and a year trying to establish peace, and promulgating rules and good customs in every district, among the laity and clergy. His efforts to teach "good rules and manners" seem to have been scarcely effectual, for we find an immediate entry of the decapitation of Ruaidhri, after he had made a "treacherous prey" in Aictheara. In the year 1128 the good Archbishop succeeded in making a year's truce between the Connaught men and the men of Munster. The following year the saint died at Ardpatrick, where he was making a visitation. He was only fifty years of age, but anxiety and care had worn him old. St. Celsus was buried at Lismore, and interred in the cemetery of the bishops.

We must now give a brief glance at the ecclesiastical history of Ireland, before narrating the events which immediately preceded the English invasion.

In the year 1111 a synod was convened at Fidh Aengussa, or Aengus Grove, near the Hill of Uisneach, in Westmeath. It was attended by fifty bishops, 300 priests, and 3,000 religious. Murtough O'Brien was also permitted to be present, and some of the nobles of his province. The object of the synod was to institute rules of life and manners for the clergy and people. St. Celsus, the Archbishop of Armagh, and Maelmuire[[238]] or Marianus O'Dunain, Archbishop of Cashel, were present. Attention had already been directed to certain abuses in ecclesiastical discipline. Such abuses must always arise from time to time in the Church, through the frailty of her members; but these abuses are always carefully reprehended as they arise, so that she is no longer responsible for them. It is remarkable that men of more than ordinary sanctity have usually been given to the Church at such periods. Some have withheld heretical emperors from deeds of evil, and some have braved the fury of heretical princes. In Ireland, happily, the rulers needed not such opposition; but when the country had been again and again devastated by war, whether from foreign or domestic sources, the intervention of saintly men was especially needed to restore peace, and to repair, as far as might be, the grievous injury which war always inflicts on the social state of those who have suffered from its devastations.

Lanfranc, the great Archbishop of Canterbury, had already noticed the state of the Irish Church. He was in constant communication with the Danish bishops, who had received consecration from him; and their accounts were probably true in the main, however coloured by prejudice. He wrote an earnest epistle to Turlough O'Brien, whom he addresses respectfully as King of Ireland, and whose virtues as a Christian prince he highly commends. His principal object appears to have been to draw the king's attention to an abuse, of which the Danes had informed him, with regard to the sacrament of matrimony. This subject shall be noticed again. Pope Gregory VII. also wrote to Turlough, but principally on the temporal authority of the Holy See.

The synod had four special subjects for consideration: (1) First, to regulate the number of bishops—an excessive and undue multiplication of episcopal dignity having arisen from the custom of creating chorepiscopi or rural bishops. It was now decided that there should be but twenty-four dioceses—twelve for the northern and twelve for the southern half of Ireland. Cashel was also recognized as an archiepiscopal see, and the successor of St. Jarlath was sometimes called Archbishop of Connaught. The custom of lay appropriations, which had obtained in some places, was also firmly denounced. This was an intolerable abuse. St. Celsus, the Archbishop of Armagh, though himself a member of the family who had usurped this office, made a special provision in his will that he should be succeeded by St. Malachy. This saint obtained a final victory over the sacrilegious innovators, but not without much personal suffering.[[239]]
