Timeline
Birth of Cicero at Arpinum
**106 BC** — Marcus Tullius Cicero was born in Arpinum, outside the old Roman aristocratic center. His non-senatorial origins would shape his lifelong sense that talent, education, and speech could open a path into public life.
Defense in Pro Roscio Amerino
**80 BC** — Cicero’s successful defense of Sextus Roscius in a politically dangerous murder case announced him as a formidable forensic orator. The case showed how law, rhetoric, and power were already entangled in the late Republic.
Study in Greece and Rhodes
**79 BC** — After leaving Rome for a period, Cicero studied Greek philosophy and rhetoric in Athens and Rhodes. This experience deepened his encounter with the schools that would later reappear in Latin form throughout his philosophical works.
Consulship and the Catilinarian Crisis
**63 BC** — As consul, Cicero confronted Catiline’s conspiracy and defended the Republic against internal threat. The episode became a lasting test case for the relation between constitutional order, emergency action, and civic virtue.
Publication of De oratore
**55 BC** — Cicero’s dialogue on the ideal orator explored the union of eloquence, knowledge, and civic responsibility. It established rhetoric as inseparable from philosophy rather than a merely technical art.
Governorship in Cilicia
**51 BC** — Cicero served as proconsul in Cilicia, an experience that forced philosophical reflection into administrative reality. The tensions between duty, ambition, and provincial rule sharpened his moral vocabulary.
Composition of De officiis
**44 BC** — Written for his son after Caesar’s assassination, De officiis became Cicero’s most influential ethical work. It sets out the relation between the honorable and the expedient in a world where republican norms were collapsing.
Philippics against Antony
**-0043-12** — Cicero delivered a series of speeches attacking Mark Antony and defending the republican cause. These speeches intensified the political conflict that would soon end in his death.
Death of Cicero
**-0043-12-07** — Cicero was killed during the proscriptions of the Second Triumvirate. His death became a symbol of the Republic’s collapse and of the vulnerability of civic speech to armed power.
Cicero’s Latin philosophical prose enters Roman education
**1 AD** — By the early imperial period, Cicero’s prose became a foundational model in Roman schooling. His language shaped how educated Romans learned to write about duty, law, and public life.
Aulus Gellius preserves and discusses Cicero
**130 AD** — Later antiquarian and educational writers preserved Cicero as a standard author for style and philosophical expression. This helped fix his place in the classical curriculum.
Augustine reads the Hortensius
**80 AD** — Augustine later recalled that Cicero’s Hortensius awakened his love of philosophy. This became one of the most famous examples of Cicero’s influence on later Christian thought, even where his doctrines were rejected.
