We find throughout the pictures a suggestion that the life of the artist was a serene and tranquil one that, while he was actively concerned with things of art throughout the district he knew best, he was sheltered by the house of the brotherhood from the tumult and turmoil that beset Fiesole, Cortona, and Foligno in the days of his youth. When he went to San Marco in Florence, where his most enduring memorial remains to this day, Fra Angelico was a man of experience and an independence so far in advance of his time, that some of the work he had accomplished comes to us to-day with a suggestion of absolute modernity in thought if not in treatment. No beauty that our more sophisticated age can reveal to us had passed him by, he paints Nature as Milton painted it when he wrote the "Masque of Comus" and "l'Allegro." And this manner of painting, so different from that of men who mix themselves with the world and surrender to its fascinations, is the painting that endures. III IN SAN MARCO It was in 1435, and Fra Angelico was approaching his fiftieth year, when the brotherhood of San Dominico quitted their convent in Fiesole and went to find a new home in Florence. With the turn of the year they left a temporary resting-place in San Giorgio Oltr' Arno and went into the ruined monastery of San Marco. This house appears to have belonged to the brotherhood of San Silvestro whose behaviour had been quite fitted to the fifteenth century in Florence, but was not altogether creditable to a religious house. Pope Eugenius IV., anxious to purify all the religious houses, gave San Marco to the Dominicans with the consent of Cosimo di Medici, and a very poor gift it was at the time, for the dormitory had been destroyed by fire, and hastily-made wooden cabins could not keep out the rain and cold wind. There was a great mortality among the brethren. Once again the Pope Eugenius interceded with the powerful ruler of Florence, and Cosimo sent for his well-beloved architect Michelozzo and commissioned him to rebuild the monastery. Naturally enough Fra Angelico, whose feeling for architecture was finely developed, came under the influence of the architect, and when the building was complete he was commissioned to adorn the walls with frescoes that should keep before the brethren the actualities of the religious life, and enable them to feel that the Spiritual Presence was in their midst. Cosimo's munificence had not stopped with the presentation of the building to the brotherhood. He equipped the monastery with a famous library, provided all the service books that were necessary, and gave the brethren for librarian a man who was destined to ascend the Fisherman's Throne and keep the keys of Heaven. The books were illuminated by Fra Angelico's brother Benedetto, who had taken the vows with him, indeed some critics are of opinion that Fra Angelico himself assisted in the work, but for this belief there appears to be but a very small foundation.
