DUAL SYSTEM OF SCHOOLS:

The schools of ancient Ireland were of two classes, lay and ecclesiastical. The ecclesiastical or monastic schools as we have seen were of Christian origin, and were conducted by monks. The lay, or secular, schools existed from a period of unknown antiquity, and in pagan times were taught by druids. The monastic schools were celebrated all over Europe during the Middle Ages: the lay schools though playing an important part in spreading learning at home are not so well known.

These two classes of schools are quite distinct all through the literary history of Ireland, and without conflicting with each other worked contemporaneously from the sixth to the nineteenth century.[197]
