It was in 1407 that Fra Angelico was admitted to the convent in Fiesole, and after seven years of peaceful life there he was obliged to flee with his companions to Foligno. It was at the time when three different popes claimed the authority over the Church of Rome, and the city of Florence declared itself in favor of Alexander V.; but the monks of Fiesole adhered to Gregory XII., and for this reason were driven from their convent. Six years they dwelt at Foligno; then the plague broke out in the country about them, and again they fled to Cortona. Pictures painted by Fra Angelico at this time still remain in the churches of Cortona. After an absence of ten years the monks returned to Fiesole, where our artist passed the next eighteen years. This was the richest period of his life: his energy was untiring, and his zeal both as an artist and as a priest burned with a steady fire. His works were sought for far and wide, and most of his easel-pictures were painted during this time. Fra Angelico would never accept the money which was paid for his work; it was given into the treasury of his convent; neither did he accept any commission without the consent of the prior. Naturally, the monk-artist executed works for the adornment of his own convent. Some of these have been sold and carried to other cities and countries, and those which remain have been too much injured and too much restored to be considered important now. [Illustration: FIG. 31.--FRA ANGELICO. _From the representation of him in the fresco of the "Last Judgment," by Fra Bartolommeo, in Santa Maria Nuova, Florence._] He painted so many pictures during this second residence at Fiesole, not only for public places, but for private citizens, that Vasari wrote: "This Father painted so many pictures, which are dispersed through the houses of the Florentines, that sometimes I am lost in wonder when I think how works so good and so many could, though in the course of many years, have been brought to perfection by one man alone."
