It is evident from this detail, taken from Machiavelli's own letters, that he was not intrusted with the secret of a prince, who, he says, never revealed his purposes to any one before the moment of execution. Yet it is also plain that, at last, he began to suspect the tragedy in preparation; and that neither the anticipation nor the fulfilment inspired him with abhorrence for the murderer; while his contempt of the confederates, and admiration of the talents and success of their destroyer, is every where apparent: nor was this a short-lived feeling. Without mentioning the "Prince," in which this act of Borgia is alluded to with praise, he is mentioned with approbation in several of his private letters. He wrote "A Description of the Method used by the Valentian Duke in putting to death Vitellozzo Vitelli, &c." This is purely narrative, and contains no word of comment or censure. There is besides a poem of his, entitled "The Decenal," in which he proposes to relate the sufferings of Italy during ten years: in this he mentions the crime of Borgia. "After the duke of Valence," he says, "had exculpated himself to the king of France, he returned to Romagna, with the intention of going against Bologna. It appears that Vitellozzo Vitelli and Paolo Orsino resolved not to assist him; and these serpents, full of venom, began to conspire together, and to tear him with their talons and teeth. Borgia, ill able to defend himself, was obliged to take refuge behind the shield of France; and to take his enemies by a snare, the basilisk whistled softly, to allure them to his den. In a short time, the traitor of Fermo, and Vitellozzo, and that Orsino who had been so much his friend, fell readily into his toils; in which the Orsino (_bear_) lost more than a paw; and Vitelli was shorn of the other horn (_alluding to his brother's death at Florence as one horn_). Perugia and Siena heard the boast of the hydra, and each tyrant fled before his fury: nor could the cardinal Orsino escape the ruin of his unhappy house, but died the victim of a thousand arts."
