But while the Irish drew to themselves from the Empire art, learning, religion, they never adopted anything of Roman methods of government in church or state. The Roman centralized authority was opposed to their whole habit of thought and genius. They made, therefore, no change in their tribal administration. As early as the second century Irishmen had learned from Gaulish landowners to divide land into estates marked out with pillar-stones which could be bought and sold, and by 700 A.D. the country was scored with fences, and farms were freely bequeathed by will. But these estates seem still to have been administered according to the common law of the tribe, and not to have followed the methods of Roman proprietors throughout the Empire. In the same way the foreign learning brought into Ireland was taught through the tribal system of schools. Lay schools formed by the Druids in old time went on as before, where students of law and history and poetry grouped their huts round the dwelling of a famous teacher, and the poor among them begged their bread in the neighbourhood. The monasteries in like manner gathered their scholars within the "rath" or earthen entrenchment, and taught them Latin, canon law, and divinity. Monastic and lay schools went on side by side, as heirs together of the national tradition and language. The most venerable saints, the highest ecclesiastics, were revered also as guardians of Irish history and law, who wrote in Irish the national tales as competent scribes and not mere copyists--men who knew all the traditions, used various sources, and shaped their story with the independence of learning. No parallel can be found in any other country to the writing down of national epics in their pagan form many centuries after the country had become Christian. In the same way European culture was not allowed to suppress the national language; clerics as well as laymen preserved the native tongue in worship and in hymns, as at Clonmacnois where the praises of St. Columcille were sung, "some in Latin, which was beguiling, some in Irish, fair the tale"; and in its famous cemetery, where kings and scholars and pilgrims of all Ireland came to lie, there is but one Latin inscription among over two hundred inscribed grave slabs that have been saved from the many lost.
