Antoninus (Antoni`nus) , Marcus Aurelius, Roman emperor, successor to the following, and who surpassed him in virtue, being also of the Stoic school and one of its most exemplary disciples, was surnamed the “philosopher,” and has left in his “Meditations” a record of his religious and moral principles (121‒180).
