The lyric Poets, in their nature courtiers and given to enjoyment, flocked, of course, to this bountiful palace. The harp was seldom silent night or day, the strains of panegyric were as prodigal and incessant as the falling of the Shannon over Killaloe. Among these eulogiums none is better known than that beautiful allegory of the poet McLaig, who sung that "a young lady of great beauty, adorned with jewels and costly dress, might perform unmolested a journey on foot through the Island, carrying a straight wand, on the top of which might be a ring of great value." The name of Brian was thus celebrated as in itself a sufficient protection of life, chastity, and property, in every corner of the Island. Not only the Poets, but the more exact and simple Annalists applaud Brian's administration of the laws, and his personal virtues. He laboured hard to restore the Christian civilization, so much defaced by two centuries of Pagan warfare. To facilitate the execution of the laws he enacted the general use of surnames, obliging the clans to take the name of a common ancestor, with the addition of "Mac," or "O"—words which signify "of," or "son of," a forefather. Thus, the Northern Hy-Nials divided into O'Neils, O'Donnells, McLaughlins, &c.; the Sil-Murray took the name of O'Conor, and Brian's own posterity became known as O'Briens. To justice he added munificence, and of this the Churches and Schools of the entire Island were the recipients. Many a desolate shrine he adorned, many a bleak chancel he hung with lamps, many a long silent tower had its bells restored. Monasteries were rebuilt, and the praise of God was kept up perpetually by a devoted brotherhood. Roads and bridges were repaired and several strong stone fortresses were erected, to command the passes of lakes and rivers. The vulnerable points along the Shannon, and the Suir, and the lakes, as far north as the Foyle, were secured by forts of clay and stone. Thirteen "royal houses" in Munster alone are said to have been by him restored to their original uses. What increases our respect for the wisdom and energy thus displayed, is the fact, that the author of so many improvements, enjoyed but five short years of peace, after his accession to the Monarchy. His administrative genius must have been great when, after a long life of warfare, he could apply himself to so many works of internal improvement and external defence.
