The lessons from Harding were a useful counter-stroke to the excessive and exaggerated Turnerism in which he had been indulging through his illness. The drawings of Amboise, the coast of Genoa, and the Glacier des Bois, though published later, were made before he had exchanged fancy for fact; and they bear, on the face of them, the obvious marks of an unhealthy state of mind. Harding, whose robust common-sense and breezy mannerism endeared him to the British amateur of his generation, was just the man to correct any morbid tendency. He had religious views in sympathy with his pupil, and he soon inoculated Ruskin with his contempt for the minor Dutch school--those bituminous landscapes, so unlike the sparkling freshness that Harding's own water-colour illustrated, and those vulgar tavern scenes, painted, he declared, by sots who disgraced art alike in their works and in their lives. Until this epoch, John Ruskin had found much that interested him in the Dutch and Flemish painters of the seventeenth century. He had classed them all together as the school of which Rubens, Vandyck and Rembrandt were the chief masters, and those as names to rank with Raphael and Michelangelo and Velasquez. He was a humorist, not without boyish delight in a good Sam-Wellerism, and so could be amused with the "drolls," until Harding appealed to his religion and morality against them. He was a chiaroscurist, and not naturally offended by their violent light and shade, until George Richmond showed him the more excellent way in colour, the glow of Venice, first hinting it at Rome in 1840, and then proving it in London in the spring of 1842 from Samuel Rogers' treasures, of which the chief (now in the National Gallery) was the "Christ appearing to the Magdalen." Much as the author of "Modern Painters" owed to these friends and teachers, and to the advantages of his varied training, he would never have written his great work without a further inspiration. Harding's especial forte was his method of drawing trees. He looked at Nature with an eye which, for his period, was singularly fresh and unprejudiced; he had a strong feeling for truth of structure as well as for picturesque effect, and he taught his pupils to observe as well as to draw. But in his own practice he rested too much on _having observed_; formed a style, and copied himself if he did not copy the old masters; Hence he held to rules of composition and conscious graces of arrangement; and while he taught naturalism in study, he followed it up with teaching artifice in practice.
