The restoration of religion, which was making such rapid progress previous to the Norman invasion, was accompanied by a relative revival of learning. The dark ages of Ireland are not those of the rest of Europe—they extend from the middle of the ninth century to the age of Brian and Malachy II. This darkness came from the North, and cleared away rapidly after the eventful day of Clontarf. The first and most natural direction which the revival took was historical investigation, and the composition of Annals. Of these invaluable records, the two of highest reputation are those of Tigernach (Tiernan) O'Broin, brought down to the year of his own death, A.D. 1088, and the chronicle of Marianus Scotus, who died at Mentz, A.D. 1086. Tiernan was abbot of Clonmacnoise, and Marian is thought to have been a monk of that monastery, as he speaks of a superior called Tigernach, under whom he had lived in Ireland. Both these learned men quote accurately the works of foreign writers; both give the dates of eclipses, in connection with historical events for several centuries before their own time; both show a familiarity with Greek and Latin authors. _Marianus_ is the first writer by whom the name _Scotia Minor_ was given to the Gaelic settlement in Caledonia, and his chronicle was an authority mainly relied on in the disputed Scottish succession in the time of Edward I. of England. With _Tigernach_, he may be considered the founder of the school of Irish Annalists, which flourished in the shelter of the great monasteries, such as Innisfallen, Boyle and Multifernan; and culminated in the great compilation made by "the Four Masters" in the Abbey of Donegal. Of the Gaelic metrical chroniclers, Flann of the Monastery, and Gilla-Coeman; of the Bards McLiag and McCoisse; of the learned professors and lectors of Lismore and Armagh—now restored for a season to studious days and peaceful nights, we must be content with the mention of their names. Of Lismore, after its restoration, an old British writer has left us this pleasant and happy picture. "It is," he says, "a famous and holy city, half of which is an asylum, into which no woman dares enter; but it is full of cells and monasteries; and religious men in great abundance abide there." Such was the promise of better days, which cheered the hopes of the Pastors of the Irish, when the twelfth century had entered on its third quarter. The pious old Gaelic proverb, which says, "on the Cross the face of Christ was looking westwards—," was again on the lips and in the hearts of men, and though much remained to be done, much had been already done, and done under difficulties greater than any that remained to conquer.
