Baccio Valori, son of Filippo, who perished by the headman’s axe, was a man of vast culture and a distinguished lawyer. He enlarged the old palace and collected a magnificent library. In a vellum bound booklet, beautifully printed in 1604, his son Filippo describes how Baccio, “after enlarging his house (without departing from the ancient lines), thought well to decorate it outside with other antiquities befitting both the land of his birth and himself as a man of letters.” These antiquities are fifteen busts of illustrious Florentines sculptured in marble in alto-rilievo, and set upon termini. In the lower row are Accursio, Torrigiano Rustichelli, surnamed de’ Valori, Marsilio Ficino, Donato Acciaiuoli, and Pier Vettori. In the alcoves between the first floor windows are Amerigo Vespucci, Leon Battista Alberti, Francesco Guicciardini, Marcello Adriano, and Vincenzio Borghini. Above are Dante, Petraca, Boccaccio, Giovanni della Casa, and Luigi Alamanni. In the corridor, “as being a more honourable place,” observes Filippo, were the Archbishop S. Antonino, S. Filippo Neri, Maestro Luigi Marsili, Lorenzo il Magnifico and Bartolomeo Cavalcanti, and a bust of Baccio Valori himself--the only one left. From the busts on the façade the palace is generally known in Florence as the Palazzo de’ Visacci, or of the Ugly Faces. Alessandro, the last of the Valori, died in 1687, and his nephew, Senator Luigi Guicciardini, inherited the palace. In 1703 he bought two small houses with stables behind, between it and the great Pazzi palace (pulled down to build the Banca d’Italia), and in 1723 a large house on the other side. His only daughter, Virginia, married Giovan Gaetano Altoviti, who incorporated the houses on either side and renovated the interior of the palace, which then took his name. The ceilings of two of the rooms were frescoed by pupils of Luca Giordano, and round the walls of one room are terra-cotta medallions, portraits of the Altoviti and the Guicciardini. One of them, wearing the well-known Florentine _lucco_, represents the great historian, Francesco Guicciardini.
