Titian in many ways summed up all that was greatest in Venetian art. His pictures have less romance than those of Giorgione, except during the short space of time when he painted under the spell of his brother artist. It is extremely difficult to distinguish then between Titian's early and Giorgione's late work. Titian perhaps had the greater intellect. Giorgione's pictures vary according to his mood, while Titian's express a less changeable personality. In spite of his youth, Giorgione made a profound impression upon all the artists of his time. They did not copy his designs, but the beauty of his pictures made them look at the world with his romantic eyes and paint in his dreamy mood. It was almost as though Giorgione had absorbed the romance of Venice into his pictures, so that for a time no Venetian painter could express Venetian romance except in Giorgione's way. But in 1518, eight years after Giorgione's death, another great innovating master was born at Venice, Tintoret by name, who in his turn opened new visions of the world to the artists of his day. While painting in the rest of Italy was becoming mannered and sentimental, lacking in power and originality, Tintoret in Venice was creating masterpieces with a very fury of invention and a corresponding swiftness of hand. He was his own chief teacher. Outside his studio he wrote upon a sign to inform or attract pupils--'The design of Michelangelo and the colouring of Titian.' Profound study of the works of these two masters is manifest in his own. Like Michelangelo he worked passionately rather than with the sober competence of Titian. His thronging visions, his multitudinous and often vast canvases are a surpassing record. Prolonged study of the human form had given to him, as to Michelangelo, a wonderful power of drawing groups of figures. His mere output was marvellous, and much of it on a grandiose scale. He covered hundreds of square feet of ceilings and walls in Venice with paintings of subjects that had been painted hundreds of times before; but each as he treated it was a new thing. Centuries of tradition governed the arrangement of such subjects as the Crucifixion and the Last Judgment, so that even the free painters of the Renaissance had deviated but little from it. In Tintoret the freedom of the Renaissance reached its height. For him tradition had no fetters. When he painted a picture of Paradise for the Doge's Palace it measured 84 by 34 feet, and contained literally hundreds of figures. His imagination was so prolific that he seems never to have repeated a figure. New forms, new postures, new groupings flowed from his brush in exhaustless multitude.
