From Wikipedia
Gaius Musonius Rufus was a Roman Stoic philosopher of the 1st century AD. He taught philosophy in Rome during the reign of Nero and so was sent into exile in 65 AD, returning to Rome only under Galba. He was allowed to stay in Rome when Vespasian banished all other philosophers from the city in 71 AD although he was eventually banished anyway, returning only after Vespasian's death. A collection of extracts from his lectures still survives. He is also remembered for being the teacher of Epictetus and Dio Chrysostom.
