Gaius Musonius Rufus was a Roman Stoic philosopher of the 1st century AD. He has been referred to as the Roman Socrates and is also remembered for being the teacher of Epictetus. 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.
