3Marcus Aurelius (April 121 AD – 17 March, 180 AD)

Considered to be the last of the “Five Good Emperors,” and a stoic philosopher, Marcus Aurelius ruled the Roman Empire from 161 to 180 AD.

A remarkable philosopher and writer, Marcus Aurelius’s stoic tome Meditations, written in Greek while on campaign between 170 and 180 AD, is still revered as a literary monument to the philosophy of service and duty, describing how to find and preserve equanimity in the midst of conflict by following nature as a source of guidance and inspiration.
