“[Roman] society became steadily more cosmopolitan. By 212 A.D., all inhabitants of the empire, except for slaves, were deemed to be citizens. The old Roman aristocracy was not fixated upon race and color. Wealth and literacy were what opened the doors of their urban mansions and country villas.”

“At this point, a social flaw that always existed with regard to the [Roman] aristocrats in their townhouses became more evident. No longer finding urban life as secure and amenable as in the early empire, the landed rich gave primacy not to their urban mansions but to their country estates, making the latter their principal residences. The dominant forces in urban life increasingly became the bishops and cathedral clergy.”

“An economy built on slave labor is vulnerable in two ways. One, availability of forced labor discourages technical innovation. The very wealthy [Roman]empire experienced no industrial revolutions. Two -- even more crucial -- slaves do not reproduce their own numbers. As Rome's wars of conquest ended, the slave population began to shrink, leading to a shortage of agricultural laborers by 200 A.D.”

“Judaism was a legal religion in the Roman Empire; Christianity was not until the first Christian emperor ascended the throne in the fourth century A.D. There were periodic persecutions of the Christians by the imperial state and local officials. The resulting martyrs, often upper-class women of unusual devotion, only served to draw more attention and converts to the Church.”

“The Roman Empire necessarily became less Roman as it became more of an Empire; until not very long after Rome gave conquerors to Britain, Britain was giving emperors to Rome. Out of Britain, as the Britons boasted, came at length the great Empress Helena, who was the mother of Constantine. And it was Constantine, as all men know, who first nailed up that proclamation which all after generations have in truth been struggling either to protect or to tear down”

“The Fathers of the American Constitution, well-versed in the classical heritage, consciously constructed an awkward governmental system like republican Rome's: much better at blocking change than facilitating it. By the early twenty-first century, the ambiance of American urban life resembled that of the Roman Empire's cities, with lavish displays of wealth standing alongside cruel poverty, although average life expectancy in the Roman Empire never rose above forty years, while in 2003 United States it's in the mid-seventies.”
