124. You think all that very wrong. So did I, once; but it was I that was wrong. A long time ago, before ever I had seen Oxford, I painted a picture of the Lake of Como, for my father. It was not at all like the Lake of Como; but I thought it rather the better for that. My father differed with me; and objected particularly to a boat with a red and yellow awning, which I had put into the most conspicuous corner of my drawing. I declared this boat to be 'necessary to the composition.' My father not the less objected, that he had never seen such a boat, either at Como or elsewhere; and suggested that if I would make the lake look a little more like water, I should be under no necessity of explaining its nature by the presence of floating objects. I thought him at the time a very simple person for his pains; but have since learned, and it is the very gist of all practical matters, which, as Professor of Fine Art, I have now to tell you, that the great point in painting a lake is--to get it to look like water.
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.
