Portraiture was the outcome of realism, and one of the most important discoveries of the Renaissance. People began to feel that they wanted not only their affluence in possessions, but also their own individual faces and features, handed down to posterity. Thus portraiture began to creep in. At first it appeared in the churches under cover of saints and Madonnas; gradually it became possible to distinguish one from another--it was not always the same face. Painters took models from life as their saints. But portraiture in painting was very slow in reaching perfection. Sculpture had accomplished that long before; now that the latest craze was for portraiture, it was the sculptors who were the most prepared to take it up, and stepped forward to execute commissions. They had plenty of material in the way of old Roman coins and busts. Donatello and Vittore Pisano were the two men who first offered to satisfy the new want. Donatello executed marvellous studies of character, and Pisano medals such as have never been seen before or since. But even these men, fine as their work undoubtedly was, felt that the public could not long remain satisfied merely with the sculptured portrait. They must have colour. Donatello, therefore, began to stain and colour his busts, showing that painting, not sculpture, was to be the portrait art of the Renaissance. Vittore Pisano also gave up his sculpture, and turned his attention to portrait-painting; but he was only an amateur in this direction, and did not meet with much success. No portrait-painter of any merit was produced in that generation. The idea was entirely new. Men had not had sufficient time in which to study the human face. The next generation ushered in Mantegna, who painted a marvellous portrait of Cardinal Sciramo; but he went too far in the other direction. He painted his man as he was--as he saw him, line for line. He painted the soul and heart of him--and the soul and the heart were black. Venice was revolted with such a portrait. It seemed indeed indecent that a man's character should be laid bare in such a way. It was a picture they did not care to hang in the Council Chamber, a picture that was unpleasant to live with. The Cardinal belonged to the State. His honour was their honour, and it must not be defiled. The Venetians came to the conclusion that portraits must be painted not in full-face but in profile. Thus the characteristics of a man, if they be not pleasant, do not come out clearly. This accounts for the number of profile portraits. The age wanted an agreeable portrait. This Giorgione provided. He realised that the treatment must always be bright, joyous, romantic. His followers trod in his footsteps: the master's style was too strong and pronounced to be much deviated from. Giorgione seems to have reached the topmost height of art at that period. Even Titian, for a generation after his death, followed in Giorgione's lines; only, Titian's work was a little more sober, a
