Abstract
To believe that we are now finished with the conception of history as magistra vitae, mistress and oracle of our lives, is perhaps to place too much faith in the imperious succession of regimes of historicity. A detour into the narrative theories of exemplification, from Karlheinz Stierle to Timothy Hampton, allows us to take a fresh look at the question of the power of the exemplary in humanist historiography of the Quattrocento. Readers of Sallustus, the tyrannicides of 15th-century Italy intended to overthrow the world by the sheer force of ancient examples, which they saw as prefiguring the conjurations to come. We attempt to grasp this through a Machiavellian analysis of the murderous sequence leading from the assassination of the Duke of Milan, Galeazzo Maria Sforza, in 1476, to the Pazzi conspiracy in Florence two years later. In this way, we can better understand what the attack was all about. By separating us from our ability to tell a story, it leaves us helplessly in the hands of a narrative machine, whose frenzies no-one can control.
