“If a man were called to fix the period in the history of the world, during which the condition of the human race was most happy and prosperous, he would, without hesitation, name that which elapsed from the death of Domitian to the accession of Commodus.”
So writes Edward Gibbon near the beginning of his classic work, “The History of the Decline and Fall of the Roman Empire.” He was referring to the second half of the period we know as the “Pax Romana,” or Roman Peace. It was an age of prosperity and wise rulership comparable to the early days of the American republic. During this time, the Roman Empire was governed by five good emperors: Nerva, Trajan, Hadrian, Antoninus Pius, and Marcus Aurelius. Of these, the most celebrated is the last.
