About this book

A pioneering discussion of Cicero’s case of Curius and its consequences for longstanding debates about the ‘politics’ of the Roman republican courts

  • Discusses the nature of competition for prestige and success among orators in the courts and other oratorical arenas of the late Roman republic
  • Offers a new interpretation of the relationship between court cases and politics in the Roman republic
  • Demonstrates how Cicero’s presentations of the past support his political and cultural agendas in his own day
  • Provides an integrated historical, political, social, and cultural account of an important Roman court case
  • Focuses attention on the centumviral court, an important Roman court that has been largely neglected by Roman historians 

In his De Oratore and Brutus, the orator and statesman Cicero introduces a trial involving a contested will, dating from his youth, that he calls the causa Curiana, or “case of Curius.” The orators advocating for the two litigants, Cicero says, employed contrasting approaches: one spoke plainly, focused on instructing the jury, and lost; the other spoke grandly, aimed at stirring the jury’s emotions, and won.

In this new study Matthew Roller examines the case and its context, addressing how Cicero presents the contrasting approaches of the orators. Roller explores the parallels between the causa Curiana and Cicero's competition with contemporary rival orators, the ‘Atticists’. The book shows how the causa Curiana gives us the (mythic) origin story in which Cicero’s “copious” style emerged triumphant over a plainer alternative, implying that it will triumph again. Through this, Roller explores how this trial’s oratory supports Cicero’s position in his political struggle with Caesar, and the Romans in their cultural rivalry with the Greeks.

Reviews

A tour de force. Roller takes an incident we thought we knew well and illustrates how its ramifications stretch much broader and deeper than imagined. Crucial not just for the Causa Curiana itself, but for anyone who thinks about Roman political culture.
Roller’s engaging study demonstrates how and why Cicero projects rhetoric at Rome as a competition and, in turn, why this matters for our understanding of Roman public speech and of Cicero’s role therein, as both an orator and a shaper of traditions around republican Rome.
