One says 'two or three,' vaguely, but the art had grown out of infancy when they appeared, and there was an enormous distance between Cimabue, whom people call the father of painting, and the Cosmas family, of whom the last died about the time that Cimabue was born. But though Cimabue was a noble, the Cosmas family who preceded him were artisans first and artists afterwards, and men of the people; and Giotto, whom Cimabue discovered sketching sheep on a piece of slate with a pointed stone, was a shepherd lad. So was Andrea Mantegna, who dominated Italian art a hundred and fifty years later--so was David, one of the greatest poets that ever lived, and so was Sixtus the Fifth, one of the strongest popes that ever reigned--all shepherds. It is rather remarkable that although so many famous painters were goldsmiths, none of the very greatest were. Among the goldsmiths were Orcagna, Ghiberti, Ghirlandajo, Antonio del Pollaiuolo, Francia, Verrocchio, Andrea del Sarto. But Benvenuto Cellini, the greatest of goldsmiths, was never a painter, and the very greatest painters were never goldsmiths, for Cimabue, Giotto, Mantegna, Lionardo da Vinci, Perugino, Raphael, Michelangelo, all began in the profession that made them the greatest artists of their age. It is very hard to get at an idea of what men thought about art in those times. Perhaps it would be near the truth to say that it was looked upon as a universal means of expression. What strikes one most in the great pictures of that time is their earnestness, not in the sense of religious faith, but in the determination to do nothing without a perfectly clear and definite meaning, which any cultivated person could understand, and at which even a child might guess. Nothing was done for effect, nothing was done merely for beauty's sake. It was as if the idea of usefulness, risen with art from the hand-crafts, underlay the intentions of beauty, or of devotion, or of history, which produced the picture. In those times, when the artist put in any accessory he asked himself: 'Does it mean anything?' whereas most painters of today, in the same case, ask themselves: 'Will it look well?' The difference between the two points of view is the difference between jesting and being in earnest--between an art that compared itself with an ideal future, and the art of today that measures itself with an ideal past. The great painters of the Renascence appealed to men and to men's selves, whereas the great painters of today appeal chiefly to men's eyes and to that much of men which can be stirred through the eye only.
