Piero de' Medici left here to go on the way to Pisa, to meet the King of France; and when he reached the king, he caused the keys of Serezzano and of Pietrasanta to be given him, and also made him promises of money. The king wishing to know whether in truth he had been given this commission, sent Lorenzo, son of Giovanni Tornabuoni, who had gone with Piero de' Medici, back to Florence, to get it confirmed by the Signoria; but they refused to confirm it. Lorenzo, in some consternation, did not return to the French camp, and Piero was rather at fault. He acted like a young fellow, and perhaps with good results, since we remained friends with the king, thank God!
5th March. Four ambassadors were chosen to go to the King of France and Naples, who were: Messer Guido Antonio, Pagolo Antonio Soderini, the Bishop de' Pazzi, and Lorenzo son of Piero Francesco de' Medici.(1)
(1) Landucci is not correct in the names of these ambassadors the work already quoted, Negotiations, etc., we read the instruction given to them and their names, but instead of Soderini and Pazzi are Bernardo Rucellai and Lorenzo Morelli. Ammirato, however, gives Soderini instead of Morelli; the truth is that the latter was appointed to replace the former, who was prevented from leaving on account of illness.
