In the Roman Republic, the investigation and prosecution of the most serious crimes, particularly murder (parricidium in its broadest sense), fell to junior magistrates known as Quaestors. These ambitious young men, at the start of their political careers, presided over the quaestiones perpetuae, the standing courts that handled major criminal cases. The Quaestor's court was the primary venue for murder trials in Rome. This episode reconstructs the procedure of a Roman murder trial. We follow the process from the initial accusation, which had to be brought by a private citizen, through the Quaestor's investigation and empaneling of a large jury of senators and equestrians. We explore the types of evidence presented, which relied heavily on witness testimony and circumstantial arguments rather than physical proof. The trial was a dramatic public contest between the rhetoric of the accuser and the defender. The Roman murder court reveals a system that was both sophisticated and deeply political. The reliance on private prosecution and the use of juries drawn from the elite classes meant that justice was often influenced by a defendant's social standing and connections. This exploration takes us to the heart of Rome’s criminal justice system in action.
