“The German economic historian Fanz Oertel in the 1950s points to another drastic consequence of a slave economy. A slave economy initially allowed an increase of productivity through the invention and use of new machinery. Roman products remained at a simple level and could be reproduced by handicraft. By the fourth century, for example, the robust pottery industry of Greece was in sharp decline because other parts of the empire also learned to make pottery."The decline in international trade in the Mediterranean in the fourth century was partly due to increasing piracy, but it was also due to lack of industrial innovation and of need for exchange of manufactured goods.”

“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.”

“There was no money economy in Egypt, and all exchange of goods was carried out by barter. Each citizen paid a tax in kind of everyt5hing he produced, and the wealth of the pharaoh thus consisted of the grain, livestock, and other goods that he took as taxes. He also received metals and other goods as tribute or in trade from abroad.”

“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 mindset of antiquity lacked economic science and sociological theory. The ancients did rather well with political narrative, although, except for Thucydides, no first-rate political annalist and analyst emerged from the literary populace. But the ancients never showed a capacity, or even an inclination, to examine closely the urban world they themselves inhabited."Neither, however, was the medieval world in the 500s through the 1500s, which succeeded antiquity, much better at economics and sociology. It was only in the eighteenth and early nineteenth centuries that this kind of thinking emerged with Adam Smith and Alexis de Tocqueville in response to industrial and political revolutions."What interested the urban dwellers of antiquity were the gods. During the Hellenistic and Roman eras the theoretical capacity of the literate urban population was given over to thinking about the nature of divinity. The chief theological formats were polytheism (many gods); monotheism (one god); dualism (two dogs, one good, the other evil); and dying and reborn savior gods that could also be fitted into the other three categories of divinity.”

“The ultimate triumph of Christianity was aided by the internal drive within Roman paganism toward some kind of monotheism. By 150 A.D., whatever vitality had once existed in ancient polytheism had mostly declined, and the gods played little or no role in individual lives. The state temples to the old gods became civic centers rather than religious entities."But paganism went about reforming itself. It drew upon the Alexandrian mystical form of Platonism, taught by Plotinus -- what we call Neoplatonism -- to conjure an image of the deity as a single spiritual fountain of life that fructifies the world."This Neoplatonic monotheism became popular in aristocratic circles in fourth-century Rome and gave such renewed vitality to paganism that the triumph of Christianity had to be bolstered by state proscription of this latter-day monotheistic paganism. By 390, Roman paganism was almost as close to monotheism as was Christianity.”

“The classical heritage as shaped by and filtered through Roman culture had two great flaws. First, it prevented the very rich oral cultures of the ancient Mediterranean from surviving from antiquity into later times. All that was left as creative forces were Greek philosophy and Roman law. These were very substantial cultures but they represented a great narrowing of what could be passed on from antiquity to later centuries..."Second, another deficiency of classical culture was its lack of social conscience, its obliviousness to the slavery, poverty, disease, and everyday cruelty endured by more than half of the fifty million people who inhabited the empire. The classical heritage represented a narrow and insensitive social and political theory reinforcing a miserably class-ridden and technologically stagnant society.”
