The particular external direction of Ruskin's work in Art was given, as usual, more or less by accident. His own practice in water-color drawing led him as a mere youth to a devoted admiration for the landscape paintings of the contemporary artist J.M.W. Turner. Turner, a romantic revolutionist against the eighteenth century theory of the grand style, was then little appreciated; and when Ruskin left the University he began, with characteristic enthusiasm, an article on 'Modern Painters,' designed to demonstrate Turner's superiority to all possible rivals. Even the first part of this work expanded itself into a volume, published in 1843, when Ruskin was only twenty-four; and at intervals during the next seventeen years he issued four additional volumes, the result of prolonged study both of Nature and of almost all the great paintings in Europe. The completed book is a discursive treatise, the various volumes necessarily written from more or less different view-points, on many of the main aspects, general and technical, of all art, literary as well as pictorial. For Ruskin held, and brilliantly demonstrated, that the underlying principles of all the Fine Arts are identical, and 'Modern Painters' contains some of the most famous and suggestive passages of general literary criticism ever written, for example those on The Pathetic Fallacy and The Grand Style. Still further, to Ruskin morality and religion are inseparable from Art, so that he deals searchingly, if incidentally, with those subjects as well. Among his fundamental principles are the ideas that a beneficent God has created the world and its beauty directly for man's use and pleasure; that all true art and all true life are service of God and should be filled with a spirit of reverence; that art should reveal truth; and that really great and good art can spring only from noble natures and a sound national life. The style of the book is as notable as the substance. It is eloquent with Ruskin's enthusiastic admiration for Beauty and with his magnificent romantic rhetoric (largely the result, according to his own testimony, of his mother's exacting drill in the Bible), which here and elsewhere make him one of the greatest of all masters of gorgeous description and of fervid exhortation. The book displays fully, too, another of his chief traits, an intolerant dogmatism, violently contemptuous of any judgments but his own. On the religious side, especially, Ruskin's Protestantism is narrow, and even bigoted, but it softens as the book proceeds (and decidedly more in his later years). With all its faults, 'Modern Painters' is probably the greatest book ever written on Art and is an immense storehouse, of noble material, and suggestion.
