Any one who has visited the National Gallery in London must have seen, and seeing must have studied, the contrasted paintings placed side by side of Turner and of Claude. They will attract attention if only because the two Turners are thus placed apart from the rooms used as a Turner Gallery, and containing the great collection of the master's works. The pictures of which I am now speaking are hung in a room principally occupied by the paintings of Murillo. As you enter you are at once attracted by four large pictures which hang on either side of the door opposite. On the right are Turner's "Dido Building Carthage," and Claude's "Embarkation of the Queen of Sheba." On the left are a "Landscape with the Sun Rising" by Turner, and "The Marriage of Isaac and Rebecca" by Claude. Nobody could fail to observe that the pictures are thus arranged for some distinct purpose. They are in fact placed side by side for the sake of comparison and contrast. They are all eminently characteristic; they have the peculiar faults and the peculiar merits of the artists. In the Claudes we have even one of those yellow trunks which are the abomination of the critic I am about to speak of, and one might almost suppose that the Queen of Sheba was embarking for Saratoga. I do not propose to criticise the pictures; but in them you have, to the full, Turner and Claude. Now in the contrast between these pictures may be found, symbolically at least, the origin and motive of John Ruskin's career. He sprang into literary life simply as a vindicator of the fame and genius of Turner. But as he went on with his task he found, or at least he convinced himself, that the vindication of the great painter was essentially a vindication of all true art. Still further proceeding with his self-imposed task, he persuaded himself that the cause of true art was identical with the cause of truth, and that truth, from Ruskin's point of view, enclosed in the same rules and principles all the morals, all the politics, all the science, industry, and daily business of life. Therefore from an art-critic he became a moralist, a political economist, a philosopher, a statesman, a preacher--anything, everything that human intelligence can impel a man to be. All that he has written since his first appeal to the public has been inspired by this conviction--that an appreciation of the truth in art reveals to him who has it the truth in everything. This belief has been the source of Mr. Ruskin's greatest successes and of his most complete and ludicrous failures. It has made him the admiration of the world one week, and the object of its placid pity or broad laughter the next. A being who could be Joan of Arc to-day and Voltaire's Pucelle to-morrow would hardly exhibit a stronger psychical paradox than the eccentric genius of Mr. Ruskin commonly displays. But in order to understand him, or to do him common justice--in order not to regard him as a mere erratic utterer of
