Under this category, however, falls to some extent the leasing or purchase by Roman capitalists of landed estates beyond Italy, with a view to carry on the cultivation of grain and the rearing of cattle on a great scale. This species of speculation, which afterwards developed to proportions so enormous, probably began particularly in Sicily, within the period now before us; seeing that the commercial restrictions imposed on the Siceliots[18], if not introduced for the very purpose, must have at least tended to give to the Roman speculators, who were exempt from such restrictions, a sort of monopoly of the profits derivable from land.
Business in all these different branches was uniformly carried on by means of slaves. The money-lenders and bankers instituted, throughout the range of their business, additional counting-houses and branch banks under the direction of their slaves and freedmen. The company, which had leased the customs-duties from the state, appointed chiefly its slaves and freedmen to levy them at each custom-house. Every one who took contracts for buildings bought architect-slaves; every one who undertook to provide spectacles or gladiatorial games on account of those giving them purchased or trained a company of slaves skilled in acting, or a band of serfs expert in the trade of fighting. The merchant imported his wares in vessels of his own under the charge of slaves or freedmen, and disposed of them by the same means in wholesale or retail. We need hardly add that the working of mines and manufactories was conducted entirely by slaves. The situation of these slaves was, no doubt, far from enviable, and was throughout less favourable than that of slaves in Greece; but, if we leave out of account the classes last mentioned, the industrial slaves found their position on the whole more tolerable than the rural serfs. They had more frequently a family and a practically independent household, with no remote prospect of obtaining freedom and property of their own. Hence such positions formed the true training school of those upstarts from the servile class, who by menial virtues and often by menial vices rose to the rank of Roman citizens and not seldom attained great prosperity, and who morally, economically, and politically contributed at least as much as the slaves themselves to the ruin of the Roman commonwealth.
The Roman mercantile transactions of this period fully kept pace with the contemporary development of political power, and were no less grand of their kind. Any one who wishes to have a clear idea of the activity of the traffic with other lands, needs only to look into the literature, more especially the comedies, of this period, in which the Phoenician merchant is brought on the stage speaking Phoenician, and the dialogue swarms with Greek and half Greek words and phrases. But the extent and zealous prosecution of Roman business-dealings may be traced most distinctly by means of coins and monetary relations. The Roman denarius quite kept pace with the Roman legions. We have already mentioned[19] that the Sicilian mints - last of all that of Syracuse in 542 - were closed or at any rate restricted to small money in consequence of the Roman conquest, and that in Sicily and Sardinia the denarius obtained legal circulation at least side by side with the older silver currency and probably very soon became the exclusive legal tender. With equal if not greater rapidity the Roman silver coinage penetrated into Spain, where the great silver-mines existed and there was virtually no earlier national coinage; at a very early period the Spanish towns even began to coin after the Roman standard[20]. On the whole, as Carthage coined only to a very limited extent[21], there existed not a single important mint in addition to that of Rome in the region of the western Mediterranean, with the exception of that of Massilia and perhaps also those of the Illyrian Greeks in Apollonia and Dyrrhachium. Accordingly, when the Romans began to establish themselves in the region of the Po, these mints were about 525 subjected to the Roman standard in such a way, that, while they retained the right of coining silver, they uniformly - and the Massiliots in particular - were led to adjust their drachma to the weight of the Roman three-quarter denarius, which the Roman government on its part began to coin, primarily for the use of Upper Italy, under the name of the "coin of victory" (victoriatus). This new system, dependent on the Roman, not merely prevailed throughout the Massiliot, Upper Italian, and Illyrian territories; but these coins even penetrated into the barbarian lands on the north, those of Massilia, for instance, into the Alpine districts along the whole basin of the Rhone, and those of Illyria as far as the modern Transylvania. The eastern half of the Mediterranean was not yet reached by the Roman money, as it had not yet fallen under the direct sovereignty of Rome; but its place was filled by gold, the true and natural medium for international and transmarine commerce. It is true that the Roman government, in conformity with its strictly conservative character, adhered - with the exception of a temporary coinage of gold occasioned by the financial embarrassment during the Hannibalic war[22] - steadfastly to the rule of coining silver only in addition to the national-Italian copper; but commerce had already assumed such dimensions, that it was able even in the absence of money to conduct its transactions with gold by weight. Of the sum in cash, which lay in the Roman treasury in 597, scarcely a sixth was coined or uncoined silver, five-sixths consisted of gold in bars[23], and beyond doubt the precious metals were found in all the chests of the larger Roman capitalists in substantially similar proportions. Already therefore gold held the first place in great transactions; and, as may be further inferred from this fact, in general commerce the preponderance belonged to that carried on with foreign lands, and particularly with the east, which since the times of Philip and Alexander the Great had adopted a gold currency.
