In 1526 the celebrated satirist Aretine, and Sansovino the sculptor, came to reside in Venice. With these distinguished men Titian contracted an intimacy, which was the source of great pleasure to him, and ceased only with their lives. When Charles V. visited Bologna in 1529, Titian was invited to that city, where he painted an equestrian portrait of the Emperor. Charles, not only an admirer but a judge of art, was astonished at a style of painting of which he had formed no previous conception; he remunerated the artist splendidly, and expressed his determination never to sit to any other master. On returning to Bologna in 1532, he summoned Titian again to his court, and engaged him in many important works, treating him on all occasions with extraordinary respect and regard. It is affirmed, that in riding through Bologna he kept upon the artist’s right hand, an act of courtesy which excited such displeasure among the courtiers that they ventured upon a remonstrance. The answer given by Charles is well known, and has been since ascribed to other monarchs: “I have many nobles in my empire, but only one Titian.” On leaving Bologna, Titian accompanied Frederic Gonzaga, Duke of Mantua, home to his own state; where, besides painting portraits of the Duke and his brother the Cardinal, he ornamented an apartment of the palace contiguous to the rooms painted by Giulio Romano, with portraits of the twelve Cæsars, taking his authorities from medals and antique marbles. In passing through Parma, on the way to Mantua, he first saw the works of Correggio, who had been engaged in painting the dome of the cathedral. So little was that great man’s genius appreciated, and such was the ignorance of his employers, that they had actually dismissed him as inadequate to the task he had undertaken; nor was he allowed to resume it, until the lavish admiration bestowed on his work by Titian, had taught them better how to estimate his talents. On returning to Venice, Titian found that a strong party had been raised in favour of Pordenone. He expressed no slight indignation at the attempt to exalt that painter to an equality with himself. Pordenone, nevertheless, was an artist of considerable powers, although certainly not qualified to compete with such an antagonist. The number of pictures which Titian continued to execute, would far exceed our limits to enumerate, and is so great as to excite astonishment; more especially as there is little evidence in his works that he was much assisted by inferior hands. In 1543, when Pope Paul III. visited Bologna, Titian painted an admirable portrait of him, and received an invitation to Rome. But he was unable to accept it, having engagements with the Duke of Urbino, whose palace he accordingly enriched with portraits of Charles V., Francis I., the Duke Guidobaldo, the Popes Sixtus IV., Julius II., and Paul III., the Cardinal of Lorraine, and Solyman, Emperor of the Turks.
