Perhaps nothing illustrates better the wealth of genius in what we have called Columbus' Century than the fact that after detailed accounts of the lives of Raphael, Michelangelo and Leonardo da Vinci, many painters of the first rank still remain to be treated of in the second place, as it were, a number of them exhibiting some quality that has given them an almost unique distinction in the history of art. Some of these great painters are acknowledged to be among the most distinguished artists of all time. When it is realized that men like Fra Angelico, Perugino, Botticelli, Titian, Correggio, Tintoretto and Veronese have to be grouped together in a single chapter, the necessities of compression in our account of the century will begin to be appreciated. Each of them deserves, for any adequate presentation of his work, not a few paragraphs, but a large volume, and about each of them indeed not one but many volumes have been written even centuries after their deaths. It must not be forgotten that almost the same abbreviation of the story must be made for any other phase of the century's achievements. When Columbus' Century opened, Fra Angelico had just been summoned to Rome to set about what has usually been considered the crowning labor of his life. This was the painting in fresco of the walls of the small oratory in the Vatican, since known as the chapel of Nicholas V, because the decoration of it was ordered by that great pontiff, a man of deep scholarship and an enlightened patron of the fine arts, whose aim to make Rome not only the centre of the religious life, but also of the best influences for art and science for all the world, {54} has come to be well recognized. Artists and art critics have been almost fulsome in their praise of these decorations of Fra Angelico. The walls were covered on three sides with two series of paintings, the upper portion illustrating the life of St. Stephen, the lower that of St. Lawrence. That two sets of subjects so similar should have been treated in close juxtaposition without any repetition in design or composition is in itself the best possible evidence of the artist's power and his constructive imagination. The designs show a freshness of conception very remarkable in a man of advanced years, yet withal there is absolutely no falling off in the power and sincerity of his art, and if anything a deepening of the religious feeling so characteristic of him. When he did this work he was probably past sixty-five years of age.
