he sent me word that he had found means to have a secret interview with the Duke of Mantua; and that he wished me, in order that we might act in concert, to send him Giuliani, whom I have always made use of in the different journeys that were to be made, because his employment of sending the news through the different parts of Italy, gave him occasion to go from one town to another, and prevented any suspicion of him, as there would have infallibly been, if I had sent any one of my household. I despatched him, therefore, with a new instruction, and not only had he an audience of the Duke of Mantua, to whom he spoke as I had desired him, but this prince even approved very much of the proposition that was made him, to deliver him from the continual inquietudes caused him by the Spaniards, and that, for this purpose, Casale should be put into your Majesty’s hands, with the understanding that I should try to obtain from you in his favour all that he could reasonably ask for. Finally, he declared that his resolution was taken upon this subject, but, that things might be better adjusted, he wished to communicate it to two of his counsellors, in whom he had the most confidence, and that he gave the selection of them to Matthioli, in order that he might be quite secure of them. Matthioli named the Marquis Cavriani and Joseph Varano, in whom he has confidence. Meanwhile the Duke of Mantua sent Giuliani to me, to acquaint me with what had passed, and recommended him to return as soon as possible, in order to receive the draft of the plan, which would then be prepared--and to convey it to me. I was much pleased, Sire, to see the affair in so good a train. I sent Giuliani back quickly, and ordered him to tell the Duke of Mantua that I entreated him to allow me to have a conference with him; that your Majesty had not as yet any knowledge of the proposed treaty, because I could not venture to go so far as that, without being certain first that he would not disavow me in what I should have the honour of writing to your Majesty, and also that he would have sufficient power to execute what had been arranged.
