As a workman, as we have seen, Tintoret was indefatigable. His lifelong yearning was not for praise, but for opportunity to work. Modesty he had to a degree unrecorded of any other painter, although none seems to have been more confident of his own powers.[11] Like Shakespeare, he wrought his masterpieces swiftly, and left them to their fate, because his imagination, like Shakespeare’s, was already on the wing for higher quarry. There was in the man an inflexible dignity, born of self-respect, which neither the allurements of popularity nor the flattery of the great could bend. When invited by the Duke of Mantua to go to that city and execute some paintings, Tintoret replied that wherever he went his wife wished to accompany him; at which the Duke bade him bring his wife and family, had them conveyed to Mantua in a state barge, and entertained them at his palace “at magnificent expense for many days.” He urged Tintoret to settle there; but the Venetian could not be persuaded to renounce his allegiance to Venice. He saw that titles would add nothing to his fame, and refused an offer of knighthood from Henry III of France. Princes and grandees and illustrious visitors to Venice went to his house; but though he received them courteously, he sought no intimacy with them. His time was too precious, his projects were too earnest, to allow of aristocratic dissipation. He had a keen sense of humor, which displayed itself now in some ready reply, now in genial conversation with his familiars. Ridolfi relates that certain prelates and senators who visited him whilst he was making sketches for the “Paradise” asked him why he worked so hurriedly, whereas John Bellini and Titian had been deliberate and painstaking. “The old masters,” said Tintoret, “had not so many to bother them as I have.” At another time, at a gathering of amateurs, a woman’s portrait by Titian was lauded. “That’s the way to paint,” said one of the critics. Tintoret went home, took a sketch by Titian and covered it with lampblack, painted a head in Titian’s manner on the same canvas, and showed it at the next meeting of these amateurs. “Ah, there’s a real Titian!” they all agreed. Tintoret rubbed off the lampblack from the original sketch and said: “This, gentlemen, is indeed by Titian; that which you have admired is mine. You see now how authority and opinion prevail in criticism, and how few there are who really understand painting.”
