A work of Christian sacrificial morality and charity, it is set in the Alpine landscape Ruskin loved and knew so well. It remains the most translated of all his works. Back at Oxford, in 1842 Ruskin sat for a pass degree, and was awarded an uncommon honorary double fourth-class degree in recognition of his achievements. Modern Painters I (1843) For much of the period from late 1840 to autumn 1842, Ruskin was abroad with his parents, mainly in Italy. His studies of Italian art were chiefly guided by George Richmond, to whom the Ruskins were introduced by Joseph Severn, a friend of Keats (whose son, Arthur Severn, later married Ruskin's cousin, Joan). He was galvanised into writing a defence of J. M. W. Turner when he read an attack on several of Turner's pictures exhibited at the Royal Academy. It recalled an attack by the critic Rev John Eagles in Blackwood's Magazine in 1836, which had prompted Ruskin to write a long essay. John James had sent the piece to Turner, who did not wish it to be published. It finally appeared in 1903. Before Ruskin began Modern Painters, John James Ruskin had begun collecting watercolours, including works by Samuel Prout and Turner. Both painters were among occasional guests of the Ruskins at Herne Hill, and 163 Denmark Hill (demolished 1947) to which the family moved in 1842. What became the first volume of Modern Painters (1843), published by Smith, Elder & Co. under the anonymous authority of "A Graduate of Oxford", was Ruskin's answer to Turner's critics. Ruskin controversially argued that modern landscape painters—and in particular Turner—were superior to the so-called "Old Masters" of the post-Renaissance period. Ruskin maintained that, unlike Turner, Old Masters such as Gaspard Dughet (Gaspar Poussin), Claude, and Salvator Rosa favoured pictorial convention, and not "truth to nature". He explained that he meant "moral as well as material truth". The job of the artist is to observe the reality of nature and not to invent it in a studioto render imaginatively on canvas what he has seen and understood, free of any rules of composition. For Ruskin, modern landscapists demonstrated superior understanding of the "truths" of water, air, clouds, stones, and vegetation, a profound appreciation of which Ruskin demonstrated in his own prose. He described works he had seen at the National Gallery and Dulwich Picture Gallery with extraordinary verbal felicity. Although critics were slow
