The column in the Piazza--taken from the Baths of Caracalla at Rome--was set here by Duke Cosimo I., to celebrate his victory over the heroic Piero Strozzi, _il maravigliosissimo bravo Piero Strozzi_ as Benvenuto Cellini calls him, in 1563. The porphyry statue of Justice was set high up on this pedestal by the most unjust of all rulers of Florence, the Grand Duke Francesco I., Cosimo's son. This same piazza witnessed a not over friendly meeting of Leonardo da Vinci and Michelangelo. Leonardo, at the time that he was engaged upon his cartoon for the Sala del Maggior Consiglio, was walking in the square, dressed in his usual sumptuous fashion, with a rose coloured tunic reaching down to his knees; when a group of citizens, who were discussing Dante, called him and asked him the meaning of a passage in question. At that moment Michelangelo passed by, and Leonardo courteously referred them to him. "Explain it yourself," said the great sculptor, "you, who made the model of a horse to cast in bronze, and could not cast it, and to your shame left it in the lurch."[50] And he abruptly turned his back on the group, leaving Leonardo red with either shame or anger. [50] See Addington Symonds' _Michelangelo_. The horse in question was the equestrian monument of Francesco Sforza. The church of Santa Trinità was originally built in the Gothic style by Niccolò Pisano, shortly after 1250, in the days of the Primo Popolo and contemporaneously with the Palazzo del Podestà. It was largely altered by Buontalenti in the last part of the sixteenth century, and has been recently completely restored. It is a fine example of Italian Gothic. In the interior, are a Mary Magdalene by Desiderio da Settignano and a marble altar by Benedetto da Rovezzano; and also, in one of the chapels of the right aisle, an Annunciation by Don Lorenzo, one of his best works, with some frescoes, partly obliterated and much "restored," by the same good Camaldolese monk.
