Wilkie’s pictures are, in one sense of the term, the most _national_ that were ever painted; and will carry down to posterity the face, character, habits, costume, etc. of the period and class which they represent, in a way that nothing else ever did or could; for they are literally the things themselves—the truth, and nothing but the truth. The painter allows himself no liberty or licence in the minutest particulars. He seems to have a superstitious reverence for the truth; and he would no more _paint_ a lie than he would tell one. I suppose he has never introduced an article of dress or furniture into any one of his pictures, that he had not actually seen worn or used under the circumstances he was representing. If he had occasion to paint a peasant who had just entered a cottage on a rainy day, he would, as a matter of conscience, leave the marks of his dirty footsteps on the threshold of the door! This scrupulous minuteness of detail, which would be the bane of some class of art, is the beauty of his, coupled, and made subservient, as it was, to the most curious, natural, and interesting development of character, sentiment and thought. But the most extraordinary examples of this artist’s professional skill, are those in which he has depicted some peculiar _expression_ in the face and action of some one of his characters. The quantity and degree of expression that he has, in several of these instances, thrown into the compass of a face and figure of less than the common miniature size, is not to be conceived without being seen, and has certainly never before been equalled in the Art. His most extraordinary efforts of this kind are two, in which the expressions are not very agreeable, but which become highly interesting, on account of the extreme difficulty that is felt to have been overcome in the production of them. One of these is an old man, in the act of coughing violently; and the other is a child, who has cut his fingers. But if this is the most extraordinary part of Wilkie’s pictures, and the part most likely to attract vulgar attention and curiosity, it is far from being the most valuable and characteristic. If it were, I should not regard him as the really great artist which I now do. The mere overcoming of difficulty, for the sake of overcoming it, and without producing any other ulterior effect, would be a mere idle waste of time and skill, and quite unworthy either of praise or attention. It is in these particular instances which I have noticed above, as in numerous others in different lines of art, a mere sleight of hand, exceedingly curious, as exhibiting the possible extent of human skill, but no more.
