Florence, as yet, had only to endure degradation and extortion, to submit to the mandates of foreign powers, to buy over and over again, at an enormous price, what was already justly her own, to return thanks for being wronged, and to ask pardon for being in the right. She was at length deprived of the blessings, even of this infamous and servile repose. Her military and political institutions were swept away together. The Medici returned, in the train of foreign invaders, from their long exile. The policy of Machiavelli was abandoned; and his public services were requited with poverty, imprisonment, and torture.
The fallen statesman still clung to his project with unabated ardor.
With the view of vindicating it from some popular objections, and of refuting some prevailing errors on the subject of military science, he wrote his "Seven Books on the Art of War." This excellent work is in the form of a dialogue.
The opinions of the writer are put into the mouth of Fabrizio Colonna, a powerful nobleman of the ecclesiastical State, and an officer of distinguished merit in the service of the King of Spain. Colonna visits Florence on his way from Lombardy to his own domains. He is invited to meet some friends at the house of Cosimo Rucellai, an amiable and accomplished young man, whose early death Machiavelli feelingly deplores. After partaking of an elegant entertainment, they retire from the heat into the most shady recesses of the garden. Fabrizio is struck by the sight of some uncommon plants. Cosimo says, that, though rare in modern days, they are frequently mentioned by the classical authors, and that his grandfather, like many other Italians, amused himself with practising the ancient methods of gardening. Fabrizio expresses his regret that those who, in later times, affected the manners of the old Romans, should select for imitation the most trifling pursuits. This leads to a conversation on the decline of military discipline, and on the best means of restoring it. The institution of the Florentine militia is ably defended, and several improvements are suggested in the details.
