Having returned to Venice, Titian there found that many gentlemen had begun to favor Pordenone, commending exceedingly the works executed by that artist in the ceiling of the Hall of the Pregai, and elsewhere. They had also procured him the commission for a small picture in the Church of San Giovanni Elemosynario, which they intended him to paint in competition with one representing that saint in his episcopal habits, which had previously been executed there by Titian. But whatever care and pains Pordenone took, he could not equal nor even approach the work of the former. Titian was then appointed to paint a picture of the Annunciation for the Church of Santa Maria degli Angeli, at Murano; but those who gave the commission for the work, not wishing to pay so much as five hundred crowns, which Titian required as its price, he sent it, by the advice of Pietro Aretino, as a gift to Charles V., who being greatly delighted with the work, made him a present of two thousand crowns. The place which the picture was to have occupied at Murano was then filled by one from the hand of Pordenone. When the emperor, some time after this, returned with his army from Hungary, and was again at Bologna, holding a conference with Clement VII., he desired to have another portrait taken of him by Titian, who, before he departed from the city, also painted that of the Cardinal Ippolito de Medici in the Hungarian dress, with another of the same prelate fully armed, which is somewhat smaller than the first; these are both now in the Guardaroba of Duke Cosimo. He painted the portraits of Alfonso, Marquis of Davalos, and of Pietro Aretino, at the same period, and these things having made him known to Federigo Gonzaga, Duke of Mantua, he entered the service of the latter, and accompanied him to his states. At Mantua our artist made a portrait of the duke, which appears to breathe, and afterward executed that of his brother, the cardinal. These being finished, he painted twelve beautiful "Heads of the Twelve Cæsars," to decorate one of the rooms erected by Giulio Romano, and when they were done, Giulio painted a "Story from the Lives of the Emperors" beneath each head.
