16th Roman Emperor from 161 to 180 and Stoic philosopher
Marcus Aurelius Antoninus (26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoic philosopher. He was the last of the rulers known as the Five Good Emperors (a term coined some 13 centuries later by Niccolò Machiavelli), and the last emperor of the Pax Romana (27 BC to 180), an age of relative peace and stability for the Roman Empire. He served as Roman consul in 140, 145, and 161.

Of things that are external, happen what will to that which can suffer by external accidents. Those things that suffer let them complain themselves, if they will; as for me, as long as I conceive no such thing, that that which is happened is evil, I have no hurt; and it is in my power not to conceive any such thing.
