I've never quite understood Edwrad Gibbon's claim that the age of the Good Emperors, which includes the reign of Marcus Aurelius, was a golden age. Didn't the Roman army suffer horrific casualties in his wars against the Marcomanni? Not only that, you also have one of the worst ever plagues to hit Europe taking place during his reign, with millions dead.
Marcus Aurelius was hardly to blame for the plague, but I hardly think his reign was a Golden Age for the Roman people.
