Cicero
Marcus Tullius Cicero, detail of a marble bust; in the Capitoline Museums, Rome.
The Allobroges, a Gallic tribe, were approached by conspirators in Rome who imprudently sought their support for the plot against the Roman Republic.1
Rather than joining the insurrection, the Allobroges envoys provided Cicero with signed documents that served as undeniable proof of the conspiracy's existence. This critical evidence allowed Cicero to arrest the conspirators, who were subsequently executed by decree of the Senate on December 5, 63 BCE.12
