Passing through the Piazza--where marble obelisks resting on tortoises mark the goals of the chariot races held here under Cosimo I. and his successors, on the Eve of St. John--and down the Via della Scala, we come to the former Spezeria of the convent, still a flourishing manufactory of perfumes, liqueurs and the like, though no longer in the hands of the friars. In what was once its chapel, are frescoes by Spinello Aretino and his pupils, painted at the end of the Trecento, and representing the Passion of Christ. They are inferior to Spinello's work at Siena and on San Miniato, but the Christ bearing the Cross has much majesty, and, in the scene of the washing of the feet, the nervous action of Judas as he starts up is finely conceived. The famous Orti Oricellari, the gardens of the Rucellai, lie further down the Via della Scala. Here in the early days of the Cinquecento the most brilliant literary circles of Florentine society met; and there was a sort of revival of the old Platonic Academy, which had died out with Marsilio Ficino. Machiavelli wrote for these gatherings his discourses on Livy and his Art of War. Although their meetings were mainly frequented by Mediceans, some of the younger members were ardent Republicans; and it was here that a conspiracy was hatched against the life of the Cardinal Giulio dei Medici, for which Jacopo da Diacceto and one of the Alamanni died upon the scaffold. In later days these Orti belonged to Bianca Cappello. At the corner of the adjoining palace is a little Madonna by Luca della Robbia; and further on, in a lunette on the right of the former church of San Jacopo in Ripoli, there is a group of Madonna and Child with St. James and St. Dominic, probably by Andrea della Robbia. In the Via di Palazzuolo, the little church of San Francesco dei Vanchetoni contains two small marble busts of children, exceedingly delicately modelled, supposed to represent the Gesù Bambino and the boy Baptist; they are ascribed to Donatello, but recent writers attribute them to Desiderio or Rossellino.
