1st-century BC philosophers

Marcus Tullius Cicero ( , ; 3 January 106 BC – 7 December 43 BC) was a Roman statesman, lawyer, scholar, philosopher, orator, and writer who tried to uphold principles during the political crises of the Roman Republic that led to the establishment of the Roman Empire. The extensive writings of Cicero include treatises on rhetoric, philosophy, and politics. He is considered one of Rome's greatest orators and prose stylists and the innovator of what became known as "Ciceronian rhetoric". Cicero was educated in Rome and in Greece. He came from a wealthy municipal () family of the Roman

Titus Lucretius Carus ( ; ;  – October 15, 55 BC) was a Roman poet and philosopher. His only known work is the philosophical poem De rerum natura, a didactic work about the tenets and philosophy of Epicureanism, which usually is translated into English as On the Nature of Things—and somewhat less often as On the Nature of the Universe. Very little is known about Lucretius's life; the only certainty is that he was either a friend or client of Gaius Memmius, to whom the poem was addressed and dedicated. De rerum natura was a considerable influence on the Augustan poets, particularly Virgil

Catius (fl. c. 50s–40s BC) was an Epicurean philosopher, identified ethnically as an Insubrian Celt from Gallia Transpadana. Epicurean works by Amafinius, Rabirius, and Catius were the earliest philosophical treatises written in Latin. Catius composed a treatise in four books on the physical world and on the highest good (De rerum natura et de summo bono). Cicero credits him, along with the lesser prose stylist Amafinius, with writing accessible texts that popularized Epicurean philosophy among the plebs, or common people.

Gaius Amafinius (or Amafanius) was one of the earliest Roman writers in favour of the Epicurean philosophy. He probably lived in the late 2nd and early 1st century BC. He wrote several works, which are censured by Cicero as deficient in arrangement and style. He is mentioned by no other ancient writer but Cicero. In the Academica, Cicero reveals that Amafinius translated the Greek concept of atoms as corpusculi ("corpuscles") in Latin.

Zarmanochegas (; according to Strabo) or Zarmarus (according to Dio Cassius) was a gymnosophist (naked philosopher), a monk of the Sramana tradition (possibly, but not necessarily a Buddhist) who, according to ancient historians such as Strabo and Dio Cassius, met Nicholas of Damascus in Antioch in the first years of Augustus' rule over the Roman Empire, and shortly thereafter proceeded to Athens where he burnt himself to death. He is estimated to have died in 19 BC.
