Management of Money
We are prevented from giving a similar comprehensive view of the moneyed economy of Rome, partly by the want of special treatises descending from Roman antiquity on the subject, partly by its very nature which was far more complex and varied than that of the Roman husbandry. So far as can be ascertained, its principles were, still less perhaps than those of husbandry, the peculiar property of the Romans; on the contrary, they were the common heritage of all ancient civilization, under which, as under that of modern times, the operations on a great scale naturally were everywhere much alike. In money matters especially the mercantile system appears to have been established in the first instance by the Greeks, and to have been simply adopted by the Romans. Yet the precision with which it was carried out and the magnitude of the scale on which its operations were conducted were so peculiarly Roman, that the spirit of the Roman economy and its grandeur whether for good or evil are pre-eminently conspicuous in its monetary transactions.
Moneylending
The starting-point of the Roman moneyed economy was of course money-lending; and no branch of commercial industry was more zealously prosecuted by the Romans than the trade of the professional money-lender (-fenerator-) and of the money-dealer or banker (-argent arius-). The transference of the charge of the larger monetary transactions from the individual capitalists to the mediating banker, who receives and makes payments for his customers, invests and borrows money, and conducts their money dealings at home and abroad—which is the mark of a developed monetary economy—was already completely carried out in the time of Cato. The bankers, however, were not only the cashiers of the rich in Rome, but everywhere insinuated themselves into minor branches of business and settled in ever-increasing numbers in the provinces and dependent states. Already throughout the whole range of the empire the business of making advances to those who wanted money began to be, so to speak, monopolized by the Romans.
