... You are informed that the Illustrious Messer Lodovico [il Moro] is ill; it seems he is afflicted with certain pains in the stomach which give him great suffering. Therefore many friends of his and of ours at Milan who are anxious about his health, have entreated us to beg the Magnificent Lorenzo to send a certain Maestro Pietro Leoni, an excellent doctor who is at Florence, to Milan, a man of great knowledge who may perhaps cure this malady.[336] We therefore desire that as soon as you receive this you go to the Magnificent Lorenzo and in our name beg him as heartily as you can, for love of us and for the interest we believe he takes in the health of the Illustrious Lodovico, to send the said Maestro Pietro immediately to Milan.--Ferrara, August 31, 1487.[337] Messer Guidone Aldrovandini, _Ambassador of Ferrara to the Republic of Florence, to_ Duke Ercole d’Este ... I hear from a good source that Messer Giovanni Jacopo de’ Trivulzi has been commissioned by the Pope to tell the Magnificent Lorenzo that he only sleeps with the eyes of the said Magnificent Lorenzo, that he must advise him, the Pontiff, wisely and guide him; if he does so the gain and the honour will be his; but if his advice be bad it will lead to the ruin of both. The Pope complains as high as the third heaven of the King’s conduct to him.[338] At the same time Messer Jacopo speaks of the cowardice, misery, and sadness of the Pope, as one speaks about a blackguard, and says that if he be not encouraged and helped to keep up his spirits, he will sink lower than any coward ever sank. To-day comes news that the King has appealed _ad novum Concilium contra Pontificem_ on account of his behaviour to H.M. This will I believe frighten the Pope, for he is a very rabbit....--Florence, September 6, 1487.[339] ... The Pope says the King cannot appeal because at Mantua, when the Diet assembled in the time of Pope Pius, all the Italian princes promised never to appeal _ad futurem Concilium_. _Item_ that H.M. expressly promised Pope Sixtus not to appeal, &c. For these reasons His Sanctity declares that he can proceed against the King. But I think he will be cautious.--Florence, September 12, 1487.[340] ... H.M. the King and the Duke of Calabria[341] declare that neither through the King of Castile, or through Milan or Florence, have they ever given a promise to pay tribute to the Pope. Here this declaration is laughed to scorn as being made by cunning evildoers, _cum sit_ that Milan and Florence made the promise and the agreement was signed with the Pope, so H.M. will have to pay the tribute. However like wise men the Signori of Florence have resolved to ignore the arrogant message of the King and the Duke, and to drink this bitter cup....--Florence, November 7, 1487.[342]
