With all his great gifts in his hands, with all the years of youth and pleasure stretching out green and fair before him, he said good-bye to earthly joys, and chose rather to serve his Master Christ in the way he thought was right. The monks of St. Dominic were the great preachers of those days--men who tried to make the world better by telling people what they ought to do, and teaching them how to live honest and good lives. But there are other ways of teaching people besides preaching, and the young monk who spent his time bending over the illuminated prayer-book, seeing with his dreamy eyes visions of saints and white-robed angels, was preparing to be a greater teacher than them all. The words of the preacher monks have passed away, and the world pays little heed to them now, but the teaching of Fra Angelico, the silent lessons of his wonderful pictures, are as fresh and clear to-day as they were in those far-off years. Great trouble was in store for the monks of the little convent at Fiesole, which Fra Angelico and his brother Benedetto had entered. Fierce struggles were going on in Italy between different religious parties, and at one time the little band of preaching monks were obliged to leave their peaceful home at Fiesole to seek shelter in other towns. But, as it turned out, this was good fortune for the young painter-monk, for in those hill towns of Umbria where the brothers sought refuge there were pictures to be studied which delighted his eyes with their beauty, and taught him many a lesson which he could never have learned on the quiet slopes of Fiesole. The hill towns of Italy are very much the same to-day as they were in those days. Long winding roads lead upwards from the plain below to the city gates, and there on the summit of the hill the little town is built. The tall white houses cluster close together, and the overhanging eaves seem almost to meet across the narrow paved streets, and always there is the great square, with the church the centre of all. It would be almost a day's journey to follow the white road that leads down from Perugia across the plain to the little hill town of Assisi, and many a spring morning saw the painter-monk setting out on the convent donkey before sunrise and returning when the sun had set. He would thread his way up between the olive-trees until he reached the city gates, and pass into the little town without hindrance. For the followers of St. Francis in their brown robes would be glad to welcome a stranger monk, though his black robe showed that he belonged to a different order. Any one who came to see the glory of their city, the church where their saint lay, which Giotto had covered with his wonderful pictures, was never refused admittance.
