Perugia stands upon a high hill, like the hill in the background of the picture of the 'Knight's Dream,' only higher, for from it you can overlook the wide Umbrian plain as far as Assisi--the home of St. Francis--which lies on the slope of the next mountain. That beautiful Umbrian landscape, in which all the towns look like castles perched upon the top of steep hills, with wide undulating ground between, occurs frequently in the pictures of Perugino, and often in those of his pupil Raphael. If you have once seen the view from Perugia for yourself, you will realize how strongly it took hold of the imagination of the young painter. Raphael had a most impressionable mind. It was part of his genius that, from every painter with whom he came in contact he imbibed the best, almost without knowing it. The artists of his day, Michelangelo, Leonardo da Vinci, and the other great men, were each severally employed in working out once and for all some particular problem in connection with their art. Michelangelo, a giant in intellect, painter, sculptor, architect, and poet, studied the human body as it had not been studied since the days of ancient Greece. His sculptured figures on the tombs of the Medici in Florence rank second only to those of the greatest Greek sculptors, and his ceiling in the Sistine Chapel is composed of a series of masterpieces of figure-painting. He devoted himself largely in his sculpture and his painting to the representation of the naked human body, and made it futile in his successors to plead ignorance as an excuse for bad drawing. As a colourist he was not pre-eminent, and his few panel pictures are for the most part unfinished.
