Raphael painted a great many pictures, but Titian must have painted more. At least one thousand have his signature. Now came wars and troubles for Venice. The Turks, French, and Venetians became at odds, and during the strife many fine works of art were lost, among them many of Titian's pictures. He had painted bishops, also the wicked Borgias, and many other great personages, but all of these are gone and to this day, no one knows what became of them. At last Titian began one of his greatest paintings, "The Tribute Money," and he set about it because he had been criticised. Some German travellers in Venice visited Titian's studio, and though they found his work very fine, one of them said that after all there was only one master able to finish a painting as it should be finished, and that was the great Dürer. The German pointed out the differences between Titian's method and Dürer's, and declared that Venetian painters never quite came up to the promise of their first pictures. Dürer's wonderful pictures were quite different from Titian's, inasmuch as his work was fuller of detail and careful finishing, but Titian was as great in another way. His effects were broader, but quite as satisfying. However, the German criticism put him on his mettle, and he answered that if he had thought the greatest value of a painting lay in its fiddling little details of finishing, he too would have painted them. To show that he could paint after Dürer's fashion, as well as his own, he undertook the "Tribute Money," and the result was a wonderful picture. Soon Rome sent for Titian. The Florentines, Raphael and Michael Angelo, were already there doing marvellous things, but the pope wished to add the genius of Titian to theirs and made him a great offer to go and live in Rome and do his future work for that city. This was an honour, but amid all his fame and the homage paid him, Titian had remembered the old home in the vale of Cadore. It was there his heart was, and he determined to return to the home of his boyhood to do his best work. So he sent his thanks and refusal to the pope, and he wrote as follows to his home folks, through the council of his town: "I, Titian of Cadore, having studied painting from childhood upward, and desirous of fame rather than profit, wish to serve the doge and signorini, rather than his highness the pope and other signori, who in past days, and even now, have urgently asked to employ me. I am therefore anxious, if it should appear feasible to paint the hall of council, beginning, if it pleases their sublimity, with the canvas of the battle on the side toward the Piazza, which is so difficult that no one as yet has had the courage to attempt it."
