The Most Ancient Lives of Saint Patrick/The Life and Acts of St. Patrick/Chapter 65
How he builded a Church of Clay alone.
And Saint Patrick journeyed round Connactia, spreading through all that region the Word of God; nor ceased he from his preaching nor from his working of miracles until all the inhabitants thereof were converted unto the true faith. And in many places builded he churches, and appointed therein priests and other ecclesiastical ministers unto the government of souls and the holy ministry. And on a time when the saint was intent on his wonted work, he came unto a certain plain, which, by its fair and pleasant site, was fitted unto the building of a church; but neither wood nor stone could be found therein. For the forest was a long way distant, and no axe could be found in those parts, nor even, if found, did any of the inhabitants understand its use. Therefore did this holy man offer up his prayers, and, being helped of heaven, he builded there a church of clay alone, and it was fashioned for that time in very handsome form, and it was endowed with the divine grace. For well is it known to have suffered naught, neither from the wind, nor from the snow, nor from the hail, nor from the rain, nor from any other inclemency of the air; but from thence even to this day is it seen to continue in its original state. And the seat of Saint Patrick, wherein sitting he was wont to preach, is still shown; and manifold and marvellous miracles are reported to have been done there.
