The Canacci came originally from S. Stefano ad Ugnano, and took their name from a certain Lapo surnamed Canaccio. That they were rich is proved by their fine old palace, which has just been restored. Ser Giovanni was notary to the Republic in 1422, but the name of Canacci would have remained comparatively unknown if the Duke Jacopo Salviati had not fallen in love with the beautiful wife of Giustino. I cannot do better than tell the sad tale in the words of an anonymous writer of the time, whose manuscript is in the Marucelliana library in Florence. “There was in Florence a gentleman of the old and honourable family of the Canacci, named Giustino, well known to me and to others still alive. He was considered a man of but little sense, because having several grown-up children by a former wife, and being near seventy years of age, he took to himself a second wife, Caterina, inferior to himself in rank, but endowed with marvellous beauty.

The Duke’s love grew every day, and the Duchess determined to cut the thread. Rumour has it that she tried to poison Caterina, but failed, and determined to take vengeance in another way. She sent for the brothers Bartolomeo and Francesco Canacci, youths of about twenty-four or so, who, though they did not inhabit, yet frequented their father’s house. After representing to them that Caterina’s licentious life brought ignominy on themselves and their posterity, and that as persons of birth and consideration it behoved them to free themselves of her presence, she promised to give them every help if they would do this, and to protect them from any future peril.... The Duchess hired four assassins from Massa, who entered the city one by one to avoid suspicion, and were kept by her until the time was ripe for effecting her abominable project. On the night of 31st December, 1638, Bartolomeo Canacci, accompanied by the aforesaid bandits, who
