“The King of the Golden River” is a delightful fairy tale told with all Ruskin’s charm of style, his appreciation of mountain scenery, and with his usual insistence upon drawing a moral. None the less, it is quite unlike his other writings. All his life long his pen was busy interpreting nature and pictures and architecture, or persuading to better views those whom he believed to be in error, or arousing, with the white heat of a prophet’s zeal, those whom he knew to be unawakened. There is indeed a good deal of the prophet about John Ruskin. Though essentially an interpreter with a singularly fine appreciation of beauty, no man of the nineteenth century felt more keenly that he had a mission, and none was more loyal to what he believed that mission to be.

While still in college, what seemed a chance incident gave occasion and direction to this mission. A certain English reviewer had ridiculed the work of the artist Turner. Now Ruskin held Turner to be the greatest landscape painter the world had seen, and he immediately wrote a notable article in his defense. Slowly this article grew into a pamphlet, and the pamphlet into a book, the first volume of “Modern Painters.” The young man awoke to find himself famous. In the next few years four more volumes were added to “Modern Painters,” and the other notable series upon art, “The Stones of Venice” and “The Seven Lamps of Architecture,” were sent forth.

Then, in 1860, when Ruskin was about forty years old, there came a great change. His heaven-born genius for making the appreciation of beauty a common possession was deflected from its true field. He had been asking himself what are the conditions that produce great art, and the answer he found declared that art cannot be separated from life, nor life from industry and industrial conditions. A civilization founded upon unrestricted competition therefore seemed to him necessarily feeble in appreciation of the beautiful, and unequal to its creation. In this way loyalty to his mission bred apparent disloyalty. Delightful discourses upon art gave way to fervid pleas for humanity. For the rest of his life he became a very earnest, if not always very wise, social reformer and a passionate pleader for what he believed to be true economic ideals.
