Amid all these preparations outwardly to win and secure fame, the curtain is now and then drawn aside, and we see with frightful evidence a boundless ambition and thirst after greatness, regardless of all means and consequences. Thus, in the preface to Machiavelli's Florentine history, in which he blames his predecessors Leonardo, Aretino and Poggio for their too considerate reticence with regard to the political parties in the city: 'They erred greatly and showed that they understood little the ambition of men and the desire to perpetuate a name. How many who could distinguish themselves by nothing praiseworthy, strove to do so by infamous deeds! ' Those writers did not consider that actions which are great in themselves, as is the case with the actions of rulers and of States, always seem to bring more glory than blame, of whatever kind they are and whatever the result of them may be. In more than one remarkable and dreadful undertaking the motive assigned by serious writers is the burning desire to achieve something great and memorable. This motive is not a mere extreme case of ordinary vanity, but something demonic, involving a surrender of the will, the use of any means, however atrocious, and even an indifference to success itself. In this sense, for example, Machiavelli conceives the character of Stefano Porcari; of the murderers of Galeazzo Maria Sforza (1476), the documents tell us about the same; and the assassination of Duke Alessandro of Florence (1537) is ascribed by Varchi himself to the thirst for fame which tormented the murderer Lorenzino Medici. Still more stress is laid on this motive by Paolo Giovio. Lorenzino, according to him, pilloried by a pamphlet of Molza, broods over a deed whose novelty shall make his disgrace forgotten, and ends by murdering his kinsman and prince. These are characteristic features of this age of overstrained and despairing passions and forces, and remind us of the burning of the temple of Diana at Ephesus in the time of Philip of Macedon
