Once, long ago, as the Chronicles tell us, Ireland was known throughout Europe as "The Isle of Saints," for St. Patrick had not long before preached the Gospel, the message of good tidings, to the warring inhabitants, to tribes of uncivilised Celts, and to marauding Danes and Vikings. He had driven out the serpent-worshippers, and consecrated the Black Stone of Tara to the worship of the True God; he had convinced the High King of the truth and reasonableness of the doctrine of the Trinity by the illustration of the shamrock leaf, and had overthrown the great idols and purified the land. Therefore the fair shores and fertile vales of Erin, the clustered islets, dropped like jewels in the azure seas, the mist-covered, heather-clad hill-sides, even the barren mountain-tops and the patches of firm ground scattered in the solitudes of fathomless bogs, were homes of pious Culdee or lonely hermit. There was still strife in Ireland, for king fought with king, and heathen marauders still vexed the land; but many warlike Irish clans or "septs" turned their ardour for fight to religious conflicts, and often every man of a tribe became a monk, so that great abbeys and tribal monasteries and schools were built on the hills where, in former days, stood the chieftain's stronghold (_rath_ or _dun_, as Irish legends name it), with its earth mounds and wooden palisades. Holy psalms and chants replaced the boastful songs of the old bards, whilst warriors accustomed to regard fighting and hunting as the only occupations worthy of a free-born man, now peacefully illuminated manuscripts or wrought at useful handicrafts. Yet still in secret they dreaded and tried to appease the wrath of the Dagda, Brigit of the Holy Fire, Ængus the Ever-Young, and the awful Washers of the Ford, the Choosers of the Slain; and to this dread was now joined the new fear of the cruel demons who obeyed Satan, the Prince of Evil. The Young Countess At this time there dwelt in Ireland the Countess Cathleen, young, good, and beautiful. Her eyes were as deep, as changeful, and as pure as the ocean that washed Erin's shores; her yellow hair, braided in two long tresses, was as bright as the golden circlet on her brow or the yellow corn in her garners; and her step was as light and proud and free as that of the deer in her wide domains. She lived in a stately castle in the midst of great forests, with the cottages of her tribesmen around her gates, and day by day and year by year she watched the changing glories of the mighty woods, as the seasons brought new beauties, till her soul was as lovely as the green woods and purple hills around. The Countess Cathleen loved the dim, mysterious forest, she loved the tales of the ancient gods, and of "Old, unhappy, far-off things, And battles long ago;" _Wordsworth._
