At the beginning of the 15th century, following the expulsion of the Medici from Florence, their return, and the foreign invasions of Italy, Tacitus returned to prominence among the theorists of classical republicanism. Niccolò Machiavelli was the first to revive him, but not (at first) in the republican model which Bruni and others had followed. One quotation from the "Annals" (13.19) appears in "The Prince" (ch. 13), advising the ruler that "it has always been the opinion and judgment of wise men that nothing can be so uncertain or unstable as fame or power not founded on its own strength". The idealized Prince bears some resemblance to Tacitus's Tiberius; a few (most notably Giuseppe Toffanin) have argued that Machiavelli had made more use of Tacitus than he let on. In fact, though, Machiavelli had probably not read the first books of the "Annals" at that time—they were published after "The Prince".
