125. So far, so good. We lay it down for a first principle that our graphic art, whether painting or sculpture, is to produce something which shall look as like Nature as possible. But now we must go one step farther, and say that it is to produce what shall look like Nature to people who know what Nature is like! You see this is at once a great restriction, as well as a great exaltation of our aim. Our business is not to deceive the simple; but to deceive the wise! Here, for instance, is a modern Italian print, representing, to the best of its power, St. Cecilia, in a brilliantly realistic manner. And the fault of the work is not in its earnest endeavor to show St. Cecilia in habit as she lived, but in that the effort could only be successful with persons unaware of the habit St. Cecilia lived in. And this condition of appeal only to the wise increases the difficulty of imitative resemblance so greatly, that, with only average skill or materials, we must surrender all hope of it, and be content with an imperfect representation, true as far as it reaches, and such as to excite the imagination of a wise beholder to complete it; though falling very far short of what either he or we should otherwise have desired. For instance, here is a suggestion, by Sir Joshua Reynolds, of the general appearance of a British Judge,--requiring the imagination of a very wise beholder indeed to fill it up, or even at first to discover what it is meant for. Nevertheless, it is better art than the Italian St. Cecilia, because the artist, however little he may have done to represent his knowledge, does, indeed, know altogether what a Judge is like, and appeals only to the criticism of those who know also.
