The son of a Roman
eques of the name of Capito, Musonius Rufus was born in
Volsinii,
Etruria about 20–30 AD. By the time of
Nero, he was already famous in
Rome, where he taught
Stoic philosophy. He was associated with the
Stoic Opposition against the perceived tyranny of Nero. He followed
Rubellius Plautus into exile when Plautus was banished by Nero (60 AD). He returned to Rome after Plautus' death (62 AD), but as a consequence of his practising and teaching
Stoicism, he became an object of suspicion and dislike at Nero's court, and was accordingly banished to the island of
Gyaros (65 AD) on a trumped-up charge of participation in the
Pisonian conspiracy. While Gyaros was "harsh and devoid of human culture", Musonius was able to survive and form a small community of philosophers. He specifically refers to his time in exile in his ninth discourse, pointing out its advantages for a practitioner of Stoicism. He returned under
Galba (68 AD). When
Marcus Antonius Primus, the general of
Vespasian, was marching upon
Rome (69 AD), he joined the ambassadors that were sent by
Vitellius to the victorious general, and going among the soldiers of the latter, preached about the blessings of peace and the dangers of war, but was soon made to stop. When the party of Vitellius gained the upper hand, Musonius was able to accuse, and obtain the conviction of,
Publius Egnatius Celer, the Stoic philosopher who had condemned
Barea Soranus. It was perhaps about this time that Musonius taught
Epictetus, his most famous student. So highly was Musonius esteemed in Rome that Vespasian allowed him to remain in Rome when the other philosophers were banished from the city (71 AD), but eventually he was exiled anyway (perhaps around 75 AD), only returning after Vespasian's death (79 AD). As to his death, we know only that he was dead by 101 AD, when
Pliny speaks of his son-in-law Artemidorus. ==Writings==
