Many of the most beautiful of the ancient poems, as well as of the popular songs, are anonymous; they are frequently found mixed up with material of the most arid description, genealogies, annals, or miscellaneous matter. It is easier to guess from the tone of the poems under what mood of mind they were composed than to tell exactly who wrote them. Even when they come down to us adorned with the name of some well-known saint or poet, we have an uncertain feeling about the accuracy of the ascription, when we find a poem whose language cannot be earlier than the tenth or eleventh century confidently connected with a writer who lived two or three centuries earlier. In some cases, no doubt, the versions we possess, though modernised in language and rhythm, are in reality old; in others the ascription probably bears witness to the desire of the author or his public to win esteem for his work by adorning it with some famous name. Some of these poems, of which only one copy has come down to us, were, however, well known in an earlier day, and are quoted in old tracts on Irish metric as examples of the metres used in the bardic schools. It is evident that though standards of taste may change, the recognition of what is really beautiful in poetry remains as a settled instinct in man's nature. Many of those poems which now appeal most strongly to ourselves took rank as verses of acknowledged merit nearer to the time of their composition. This we can deduce from their use as examples worthy of imitation in these mediæval Irish text-books, where the names of songs we still admire are quoted as specimens of good poetry.
It is remarkable that a very large proportion of fine poetry comes to us from the period of the Norse invasions, a time which we are accustomed to think of as one continuous series of wars, raids, and burnings; but which, if we may judge by what has come down to us of its verse, shows us that the Irish gentleman of that day had ideas of refinement that raise him far above the mere fighting clansman; his critical view of literature was a severe one. The fine freedom shown in many of these poems is surprising, both as regards the sentiments and the metres. They possess a mastery of form that argues a high cultivation, not only of the special art of poetry, but of the whole intellectual faculties of the writers.
Some of these poems are strangely modern, even fin de siècle in their tone. The poem of the "Old Woman of Beare" has often been compared to Villon's "Regrets de la Belle Heaulmière ja parvenue à viellesse," or to Béranger's "Grand'mère." But the Irish poem is far more artistically wrought than either of these comparatively modern poems. For in the ancient verses, the old woman is set, a lonely and forsaken figure, against the background of the ebbing tide, and the slow throbs of her heart, worn with age and sin, beat in unison with the retreating motion of the wave. There is also a further significance in the poem which we must not miss. It is the earliest of the long series of allegorical songs in which Ireland is depicted under the form of a woman; though, unlike her successors of a later day, she is here represented, not as a fair maiden, a Grainne Mhaol, or Kathleen ni Houlahan, or Little Mary Cuillenan, but as an aged joyless hag, forlorn and censorious, bemoaning the loss of bygone pleasures, and the gravity of her nun's veil. The "Cailleach Bheara," the "Hag" or "Nun of Beare" is known in many place-names in Ireland. It is on Slieve na Callighe, or the "Hill of the Hag" or "Nun," in Co. Meath that the great cairns and tumuli of Lough Crew are found; it was evidently, like the neighbourhood of the Boyne, a place of pagan sanctity; and such names as Tober na Callighe Bheara, the "Well of the Hag of Beare," are found in different parts of the country. The "Hag of Beare" seems to be symbolic of pagan Ireland, regretting the stricter regime of Christianity, and the changes that time had brought about. The curious legend which prefaces the poem suggests the same idea. She is said to have seen seven periods of youth, and to have outlived tribes and races descended from her. For a hundred years of old age she wore the veil of a nun. "Thereupon old age and infirmity came upon her." We catch the same note of regret for the days of paganism through many legends and poems. It is mystical and veiled in such stories as that of "King Murtough and the Witch-woman"; it is fierce, but also often touched by the grotesque, in the innumerable colloquies between Patrick and Oisín (Ossian), the last of the ancient pagan heroes. But in all this there is a note of apology. It is not so outspoken in its revolt against the new system of life and thought as are the Norse chronicles and the Icelandic Sagas. After all, Christianity was an accomplished thing; quietly but persistently it took its place, sweeping into its fold chiefs and common folk alike. No resistance could stop this universal progress. And the literary man or the peasant, dwelling on his early legends, the outcome of a state of thought passed or passing away, dared only half-heartedly bemoan the former days, when wars and raids, the "Creach" and the "Táin" were the highest way of life for a brave man, and no Christian doctrine of forgiveness of enemies and charity to foes had come in to perplex his thoughts and confuse their issues. The Raid remained, it was an essential part of actual life; and burnings and wars went on as before, but they were no longer, theoretically, at least, matters to win praise and honour, they were condemned beforehand by the Christian ethic. A chief, to hold his own, must still throw open doors of hospitality to his tribe, must dispense largesse to all-comers, must gather about his board the neighbours and dependents in riotous assemblies and festivals. But all this the Christian monk and priest looked upon with suspicion; they bade him fill his thoughts with a future Kingdom, rather than with the earthly one to which he had been born, and to keep his soul in humble readiness by prayers and fastings, by seclusion and self-sacrifice. The great disjointure is everywhere apparent; chiefs are seen flying from their plain duties to their clans in order to win a heavenly chiefdom, not of this world; kings retire into hermitages, and whole villages take on the aspect and system of life of the monastery. To escape a network of religious service so closely spread throughout the country was impossible; all that the half-convinced could do was to relieve his soul in legend and song and jest. Hence the large amount of this literature of protest, coming to us curiously side by side with poems breathing the very spirit of religious devotion, the work of peaceful recluse or retired monk.
For the movement had its other aspect. If the warrior or chief resigned much in becoming a Christian monk, there is no doubt that he gained as well. Contemporaneous religious poetry in the Middle Ages is elsewhere overshadowed by the cast of theologic thought. The "world" from which the saint must flee is no mere symbol, denoting the perils of evil courses; it is the actual visible earth, its hills and trees and flowers, and the beauty of its human inhabitants that are in themselves a danger and a snare. St. Bernard walking round the Lake of Geneva, unconscious of its presence and blind to its loveliness, is a fit symbol of the tendency of the religious mind in the Middle Ages. Sin and repentance, the fall and redemption, hell and heaven, occupied the religious man's every thought; beside such weighty themes the outward life became almost negligible. If he dared to turn his mind towards it at all, it was in order to extract from it some warning of peril, or some allegory of things divine. In essence, the "world" was nothing else than a peril to be renounced and if possible entirely abandoned.
But the Irish monk showed no such inclination, suffered no such terrors. His joy in nature grew with his loving association with her moods. He refused to mingle the idea of evil with what God had made so good. If he sought for symbols, he found only symbols of purity and holiness. The pool beside his hut, the rill that flowed across his green, became to his watchful eye the manifestation of a divine spirit washing away sin; if the birds sang sweetly above his door, they were the choristers of God; if the wild beasts gathered to their nightly tryst, were they not the congregation of intelligent beings whom God Himself would most desire? The friendly badgers or foxes of the wood that came forth, undismayed by the white or brown-robed figure who seemed to have taken up his lasting abode amongst them, became to his mind fellow-monks, authorised members of his strange community. Amongst his feathered and furred associates, he read his Psalms and Hours in peace; sang his periodic hymn to St. Hilary or St. Brigit, and performed his innumerable genuflexions and "cross-vigils." Here, from time to time, he poured forth in spontaneous song his joy in the life that he had elected as his own. When King Guaire of Connaught stands at the door of the hermitage in which his brother Marvan had taken refuge from the bustle of court life, and asks him why he had sacrificed so much, Marvan bursts forth into a poem in praise of his hermit life, and the King is fain to confess that the choice of the recluse was the wiser one; when St. Cellach of Killala is dragged into the forest by his comrades and threatened with death, not even the sight of the four murderers lying at his feet with swords ready drawn in their hands to slay him
