(2) The Piazza de' Tornaquinci; the Strozzi had permission from the Republic and from the consertia (assembly) of this family to occupy a portion of it. These records relating to the building of the palace are much more copious than those written by its founder and published in the appendix to the Vita di Filippo Strozzi (Firenzi, 1851).

(During his absence Michelangelo was to receive the commission for the Battle of Cascina.) His mission was preceded by a diplomatic action conducted by Machiavelli himself. It can be inferred, therefore, that it was Machiavelli who suggested Leonardo's name for the programme of fortification projects suggested by Jacopo IV Appiano, Lord of Piombino, an ally of the Florentines at the time of the Pisian war, 1503-4, when Leonardo had already been consulted on the project of diverting the Arno River for strategic reasons, and when Antonio da Sangallo the Elder was the chief military architect of the Florentine Republic. Leonardo's activity at Piombino, revealed by newly discovered evidence, included the study of the city walls, the citadel and the main gate.
