Duke Ercole d’Este _to_ Messer Aldrovandini, _Ambassador of Ferraro to the Republic of Florence_ Messer Aldrovandini,--As soon as you receive this our letter contrive to see the Magnificent Lorenzo _solus cum solo_, and inform him most secretly that we are advised by our ambassador at Venice that a Genoese envoy has arrived there in disguise, with secret instructions from his prince, and his ambassador has asked that Illustrious Signoria to enter into a treaty, and to give counsel and aid against the Magnificent Signoria of Florence. Not desiring to make this public, but on the contrary to keep it secret, they requested the Illustrious Signoria of Venice to let Signor Roberto [San Severino] enter his service, to whom his Commune offers 20,000 men for making war against the Florentines. He complained that the Illustrious Lord Lodovico kept his ambassadors some time in Milan and sent them home without concluding anything, on the pretext that he wanted to reconcile them with the Florentines, towards whom they say he is too tender. It has been determined not to give an immediate answer to this envoy but to keep him amused with hopes until it is known whether the league and friendship which is now being arranged between the Pope and the Signoria is concluded. To accelerate this the Signoria of Venice have sent Antonio Vinciguerra their secretary in all haste to Rome, who passed through here three nights ago on his way to Ravenna, where horses were ready to take him to Rome. With him went a secretary of the Legate, who is at Venice, sent by the Legate, so that by what we see and hear the affair is on the point of being concluded unless steps can be taken to stop it. Of the important results to Italian matters, _et presentim_ to our Illustrious League, I leave the Magnificent Lorenzo to judge. I beg you _ex corde_ to keep this news secret, for if by chance it was known from whence it came, besides the danger our ambassador at Venice would run, you would lose the benefit of being advised of matters which deeply concern that Illustrious Signoria and His Magnificence.--Ferrara, November 18, 1486.[327] Messer Guidone Aldrovandini, _Ambassador of Ferrara to the Republic of Florence, to the_ Duke Ercole d’Este
