And so he got together a mass of examples in addition to the Turners which he had already given to the University galleries. He placed in the school a few pictures by Tintoret, some drawings by Rossetti, Holman Hunt, and Burne-Jones, and a great number of fine casts and engravings. He arranged a series of studies by himself and others, as "copies," fitted, like the Turners in the National Gallery, with sliding frames in cabinets for convenient reference and removal. After spending most of his first Lent Term in this work, he went home for a month to prepare a catalogue, which was published the same year: the school not being finally opened until October, 1871. During these first visits to Oxford he was the guest of Sir Henry Acland; on April 29, 1871, Professor Ruskin, already honorary student of Christ Church, was elected to an honorary fellowship at Corpus, and enabled to occupy rooms, vacated by the Rev. Henry Furneaux, who gave up his fellowship on marrying Mr. Arthur Severn's twin-sister.[22]

After this work well begun, he went abroad for a vacation tour with a party of friends—as in 1866; Lady Trevelyan's sister, Mrs. Hilliard, to chaperone the same young ladies, and three servants with them. They started on April 27th; stayed awhile at Meurice's to see Paris; and at Geneva, to go up the Salève, twice, in bitter black east wind. Then across the Simplon to Milan. After a month at Venice and Verona, where he recurred to his scheme against inundation, then ridiculed by Punch, but afterwards taken up seriously by the Italians, they went to Florence, and met Professor Norton. In the end of June they turned homewards, by Pisa and Lucca, Milan and Como, and went to visit their friend Marie of the Giessbach.

At the Giessbach they spent a fortnight, enjoying the July weather and glorious walks, in the middle of which war was suddenly declared between Germany and France. The summons of their German waiter to join his regiment brought the news home to them, as such personal examples do, more than columns of newspaper print; and as hostilities were rapidly beginning, Ruskin, with the gloomiest forebodings for the beautiful country he loved, took his party home straight across France, before the ways should be closed.

August was a month of feverish suspense to everybody; to no one more than to Ruskin, who watched the progress of the armies while he worked day by day at the British Museum preparing lectures for next term. This was the course on Greek relief-sculpture, published as "Aratra Pentelici."[23] It was a happy thought to illustrate his subject from coins, rather than from disputed and mutilated fragments; and he worked into it his revised theory of the origin of art—not Schiller's nor Herbert Spencer's, and yet akin to theirs of the "Spieltrieb,"—involving the notion of doll-play;—man as a child, re-creating himself, in a double sense; imitating the creation of the world and really creating a sort of secondary life in his art, to play with, or to worship. In the last lecture of the series (published separately) the Professor compared—as the outcome of classic art in Renaissance times—Michelangelo and Tintoret, greatly to the disadvantage of Michelangelo. This heresy against a popular creed served as text for some severe criticism; but as he said in a prefatory note to the pamphlet, readers "must observe that its business is only to point out what is to be blamed in Michael Angelo, and that it assumes the fact of his power to be generally known," and he referred to Mr. Tyrwhitt's "Lectures on Christian Art" for the opposite side of the question.

Meanwhile the war was raging. Ruskin was asked by his friends to raise his voice against the ravage of France; but he replied that it was inevitable. At last, in October, he read how Rosa Bonheur and Edouard Frère had been permitted to pass through the German lines, and next day came the news of the bombardment of Strasburg, with anticipations of the destruction of the Cathedral, library, and picture galleries, foretelling, as it seemed, the more terrible and irreparable ruin of the treasure-houses of art in Paris. His heart was with the French, and he broke silence in the bitterness of his spirit, upbraiding their disorder and showing how the German success was the victory of "one of the truest monarchies and schools of honour and obedience yet organised under heaven." He hoped that Germany, now that she had shown her power, would withdraw, and demand no indemnity. But that was too much to ask.

Before long Paris itself became the scene of action, and in January 1871 was besieged and bombarded. So much of Ruskin's work and affection had been given to French Gothic that he could not endure to think of his beloved Sainte Chapelle as being actually under fire—to say nothing of the horror of human suffering in a siege. He joined Cardinal (then Archbishop) Manning, Professor Huxley, Sir John Lubbock and James Knowles in forming a "Paris Food Fund," which shortly united with the Lord Mayor's committee for the general relief of the besieged. The day after writing on the Sainte Chapelle he attended the meeting of the Mansion House, and gave a subscription of £50. He followed events anxiously through the storm of the Commune and its fearful ending, angered at the fratricide and anarchy which no Mansion House help could avert or repair.

It was no time for talking on art, he felt: instead of the full course, he could only manage three lectures on landscape, and these not so completely prepared as to make them ready for printing. Before Christmas he had been once more to Woolwich, where Colonel Brackenbury invited him to address the cadets at the prize-giving of the Science and Art Department, December 13, 1870, in which the Rev. W. Kingsley, an old friend of Ruskin's and of Turner's, was one of the masters. Two of the lectures of the "Crown of Wild Olive" had been given there, with more than usual animation, and enthusiastically received by crowded and distinguished audiences, among whom was Prince Arthur (the Duke of Connaught), then at the Royal Military Academy. This time it was the "Story of Arachne," an address on education and aims in life; opening with reminiscences of his own childhood, and pleasantly telling the Greek myths of the spider and the ant, with interpretations for the times.

In the three lectures on landscape, given January 20, February 9 and 23, 1871, he dwelt on the necessity of human and historic interest in scenery; and compared Greek "solidity and veracity" with Gothic "spirituality and mendacity," Greek chiaroscuro and tranquil activity with Gothic colour and "passionate rest." Botticelli's "Nativity" (now in the National Gallery) was then being shown at the Old Master's Exhibition, and Ruskin took it, along with the works of Cima, as a type of one form of Greek Art.

In April, 1871, his cousin, Miss Agnew, who had been seven years at Denmark Hill, was married to Mr. Arthur Severn. Ruskin, who had added to his other work the additional labour of "Fors Clavigera," went for a summer's change to Matlock. July opened with cold, dry, dark weather, dangerous for out-of-door sketching. One morning early—for he was always an early riser—he took a chill while painting a spray of wild roses before breakfast (the drawing now in the Oxford Schools). He was already overworked, and it ended in a severe attack of internal inflammation, which nearly cost him his life. He was a difficult patient to deal with. The local practitioner who attended him used to tell how he refused remedies, and in the height of the disease asked what would be worst for him. He took it; and to everybody's surprise, recovered.[24]

During the illness at Matlock his thoughts reverted to the old "Iteriad" times of forty years before, when he had travelled with his parents and cousin Mary from that same "New Bath Hotel," where he was now lying, to the Lakes; and again he wearied for "the heights that look adown upon the dale. The crags are lone on Coniston." If he could only lie down there, he said, he should get well again.
