In a letter of on Titian

“Most Illustrious and best Lord Uncle, — Having asked Titian, the bearer of these presents, to execute certain work for me, he declared himself unable to serve me at present, because of a promise to do certain things for your Excellency which require time. For this reason I send him to attend your Excellency. But I beg he may be sent back at once to expedite the work I have on hand for him, which will take but a few days. As soon as he shall have done he can return to the service of your Excellency, and in this your Excellency will do me a singular pleasure to whom I stand greatly recommended.”

“M. Tuciano [Titian] — I received the two beautiful pictures which you were pleased to send as a present to me, and am very grateful for them, not only because I was most desirous of possessing works from such skillful hands as yours, knowing as I do how clever you are in the art of painting, but because you send me portraits of two persons who were always and still are dear to me; —so like too that nature itself could not have made them more so; I therefore thank you, and shall hold these pictures dear for your sake; and you may be assured that nothing you could have done would have been more agreeable to me, or make me feel myself more under obligation. When I can I shall ever be ready to do you a pleasure, and always be disposed and inclined to consult your wishes.”

“..Titian the painter is at Augsburg, whither the Emperor [Charles V] has called him, and he has constant access to his Majesty, whose health is on the whole but middling.”
