Happily, too, Titian's art grew with his age. Practice and experience ripened it, and some of his finest pictures were painted when he was past the span of life that the Psalmist has allotted to man. He covered every field, no form of painting seems to have come amiss to him. Altar-pieces, portraits, historical pictures, mythological and allegorical subjects, one and all claimed his attention from time to time, and though we are all entitled to express our preference, there will be few to say that he failed in any style of work. Perhaps he was least successful in allegorical subjects, and in the portraits of women, but, if this be so, his failure is merely relative, he attained such heights in mythological subjects and men's portraits, that the other work is not so good by comparison. If he gave us no picture devoted entirely to landscape it is worth remarking that the appeal of nature was an ever growing one. The impression given him by the mountains round Cadore was never lost. From the time when he completed Gian Bellini's last picture down to the time when the plague came to Venice and found him with an unfinished picture on his easel, the attraction of the countryside he knew so well was always with him, and he lost no opportunity of expressing it. Gian Bellini had opened the walls that shut in the Madonna and the Saints of the earlier masters, he had given the world glimpses of exquisite landscape through which the romance woven round his figures seemed to spread. Titian opened the gates still further, giving a larger, wider, and more splendid view, convincing his contemporaries and successors that landscape could never more be overlooked.
