Machiavelli, it might seem, ought to have been impressed by a prince who baffled his enemies, surmounted the consequences of his mistakes and died in his bed at the age of seventy-seven. Not so. There is a precluding fact, not noted, for example, in Toffanin’s Machiavelli e il Tacitismo, a diffuse production perhaps more praised than read. That is, the Tiberian books of the Annals were not published until 1515. Anyhow, the Florentine Republican abode under the spell of Livy - whose primacy was soon to pass. Livy furnished inadequate instruction for an age of courts and despots, of religious wars and peace more murderous than warfare.
