In his work focused mainly on republicanism, "Discourses on the First Ten Books of Livy", Machiavelli returned to Bruni's republican perspective on Tacitus. Four overt references appear in the work. Chapter 1.10 follows Tacitus ("Histories" 1.1), and Bruni, on the chilling effects of monarchy. Chapter 1.29 quotes the "Histories" (4.3) on the burden of gratitude and the pleasure of revenge. Chapter 3.6 quotes Tacitus: "men have to honor things past but obey the present, and ought to desire good Princes, but tolerate the ones they have". 3.19 twists a line from Tacitus (3.55) into something very similar to Machiavelli's famous maxim that it is better for a prince to be feared than loved. (The original made a very different point: that respect for the Emperor and a desire to conform, not fear and punishment, kept certain senators in line.) Many covert references appear: Machiavelli generally follows Tacitus's decidedly negative slant on the history of Rome under the Emperors.
