"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."
