Your Ceasarean Majesty, I consigned to senõr Don Diego di Mendoza, the two portraits of the most serene Empress [ Isabella ], in which I have used all the diligence of which I was capable. I should have liked to take them to your Majesty in person, but that my age and the length of the journey forbade such a course. I beg your Majesty to send me words of the faults or failings which I may have made, and return the pictures that I may correct them. Your Majesty may not permit anyone else to lay hand on them.... Your Majesty's most humble and constant servant, Titiano.
