Contemporary responses to Plato’s Republic rarely examine its complex relationship to festivals and sacrifice. Recovering the importance of the festival to Plato’s concerns, this article reveals Plato’s displacement of the sacrificial violence of ancient Greek festivals with the language and possibilities (including notions of responsibility) of money. The first section introduces, through the opening scenes of the Republic, the significance of money in Ancient Greece, particularly its affiliation with the ritual dynamics of the festival. The second section focuses on animal sacrifice, developing the central claim that much of the Republic imagines replacing the power of sacrifice to hold a conflicted polis together with the logic of money to organize and maintain the city. To explore the ramifications of this shift, the third section of the essay turns to the problems of visibility and sacrifice, arguing that the shift from festival to monetary political practice obscures the violence of political and monetary life; an obscurity reproduced in Giorgio Agamben’s neglect of ancient Greece in his account of the relationship between sacrifice and political status. This reading provokes an engagement with the contemporary acceptance of monetary violence leading to the conclusion that the violence and death resulting from monetary practice should be considered political violence, not sacrifice.
