On the other hand, calling now and again at the Librairie Internationale, Zola there acquired no little information which became useful for his contributions to "L'Événement," besides making the acquaintance of various literary men. But his old friends remained his favourite ones, and Cézanne, the painter, ranked foremost among them. He, Cézanne, had become a fervent partisan of the new school of art, the school which Zola called that of the Open Air, and which led to Impressionism. Zola himself had strong artistic leanings and sympathies; he spent hours in the studio of his friend, who introduced him to several other young painters, first Guillemet, then Édouard Béliard, Pissarro, Claude Monet, Degas, Renoir, Fantin-Latour,--as well as Théodore Duret, art critic and subsequently historian--with all whom he often discussed art at the famous Café Guerbois at Batignolles. A little later, Guillemet and Duranty the novelist,[8] with whom Zola had kept up an intercourse since leaving Hachette's, introduced him to Édouard Manet, the recognised leader of the new school; and in all likelihood Zola, about the same time, came across the unlucky Léopold Tabar, a born colourist, whom Delacroix had favoured and helped. Tabar produced one striking and almost perfect painting, a "Saint Sebastian," but the rest of his life was consumed in ineffectual efforts. His sketches were admirable, but he could never finish a picture, and his failures were accentuated by his constant ambition to produce something huge, something colossal. Yet for years he was regarded as a coming great man. He had failed with his last picture, no doubt, but his next would be a masterpiece. He died at last in misery. And so much of his story corresponds with that of Zola's novel, "L'Œuvre," that it seems certain the author must have met the unfortunate painter, and have blended his life with that of Cézanne and others when preparing his study on the art-world of Paris.[9]
