The Roman Empire had many highs and lows throughout its existence, but none rivaled the Second Century A.D. It was a time of relative peace and prosperity. During this time, there were five emperors, often called the "Five Good Emperors." The last of these Emperors was Marcus Aurelius. Marcus Aurelius is most known for his philosophical musings. Especially one brand of philosophical thought called "Stoicism". This philosophy has as much application in today's world as it did in his age. Marcus put his philosophical musings to paper; this work is now famously known as the Meditations.
