system of employing slaves in every more considerable undertaking intervened: in the construction of the Marcian aqueduct, for instance, the government concluded contracts for building and materials simultaneously with 3000 master-tradesmen, each of whom then performed the work contracted for with his band of slaves.
The most brilliant, or rather the only brilliant, side of Roman private economics was money-dealing and commerce. First of all stood the leasing of the domains and of the taxes, through which a large, perhaps the larger, part of the income of the Roman state flowed into the pockets of the Roman capitalists. The money- dealings, moreover, throughout the range of the Roman state were monopolized by the Romans; every penny circulated in Gaul, it is said in a writing issued soon after the end of this period, passes through the books of the Roman merchants, and so it was doubtless everywhere. The co-operation of rude economic conditions and of the unscrupulous employment of Rome's political ascendency for the benefit of the private interests of every wealthy Roman rendered a usurious system of interest universal, as is shown for example by the treatment of the war-tax imposed by Sulla on the province of Asia in 670, which the Roman capitalists advanced; it swelled with paid and unpaid interest within fourteen years to sixfold its original amount. The communities had to sell their public buildings, their works of art and jewels, parents had to sell their grown-up children, in order to meet the claims of the Roman creditor: it was no rare occurrence for the debtor to be not merely subjected to moral torture, but directly placed upon the rack. To these sources of gain fell to be added the wholesale traffic. The exports and imports of Italy were very considerable. The former consisted chiefly of wine and oil, with which Italy and Greece almost exclusively - for the production of wine in the Massiliot and Turdetanian territories can at that time have been but small - supplied the whole region of the Mediterranean; Italian wine was sent in considerable quantities to the Balearic islands and Celtiberia, to Africa, which was merely a corn and pasture country, to Narbo and into the interior of Gaul. Still more considerable was the import to Italy, where at that time all luxury was concentrated, and whither most articles of luxury for food, drink, or clothing, ornaments, books, household furniture, works of art were imported by sea. The traffic in slaves, above all, received through the ever-increasing demand of the Roman merchants an impetus to which no parallel had been known in the region of the Mediterranean, and which stood in the closest connection with the flourishing of piracy. All lands and all nations were laid under contribution for slaves, but the places where they were chiefly captured were Syria and the interior of Asia Minor[27].
In Italy the transmarine imports were chiefly concentrated in the two great emporia on the Tyrrhene sea, Ostia and Puteoli. The grain destined for the capital was brought to Ostia, which was far from having a good roadstead, but, as being the nearest port to Rome, was the most appropriate mart for less valuable wares; whereas the traffic in luxuries with the east was directed mainly to Puteoli, which recommended itself by its good harbour for ships with valuable cargoes, and presented to merchants a market in its immediate neighbourhood little inferior to that of the capital - the district of Baiae, which came to be more and more filled with villas. For a long time this latter traffic was conducted through Corinth and after its destruction through Delos, and in this sense accordingly Puteoli is called by Lucilius the Italian 'Little Delos'; but after the catastrophe which befel Delos in the Mithradatic war[28], and from which it never recovered, the Puteolans entered into direct commercial connections with Syria and Alexandria, and their city became more and more decidedly the first seat of transmarine commerce in Italy. But it was not merely the gain which was made by the Italian exports and imports, that fell mainly to the Italians; at Narbo they competed in the Celtic trade with the Massiliots, and in general it admits of no doubt that the Roman merchants to be met with everywhere, floating or settled, took to themselves the best share of all speculations.
Putting together these phenomena, we recognize as the most prominent feature in the private economy of this epoch the financial oligarchy of Roman capitalists standing alongside of, and on a par with, the political oligarchy. In their hands were united the rents of the soil of almost all Italy and of the best portions of the provincial territory, the proceeds at usury of the capital monopolized by them, the commercial gain from the whole empire, and lastly, a very considerable part of the Roman state-revenue in the form of profits accruing from the lease of that revenue.
The daily-increasing accumulation of capital is evident in the rise of the average rate of wealth: 3,000,000 sesterces (30,000 pounds) was now a moderate senatorial, 2,000,000 (20,000 pounds) was a decent equestrian fortune; the property of the wealthiest man of the Gracchan age, Publius Crassus consul in 623 was estimated at 100,000,000 sesterces (1,000,000 pounds). It is no wonder, that this capitalist order exercised a preponderant influence on external policy; that it destroyed out of commercial rivalry Carthage and Corinth[29] as the Etruscans had formerly destroyed Alalia and the Syracusans Caere; that it in spite of the senate upheld the colony of Narbo[30]. It is likewise no wonder, that this capitalist oligarchy engaged in earnest and often victorious competition with the oligarchy of the nobles in internal politics. But it is also no wonder, that ruined men of wealth put themselves at the head of bands of revolted slaves[31], and rudely reminded the public that the transition is easy from the haunts of fashionable debauchery to the robber's cave. It is no wonder, that that financial tower of Babel, with its foundation not purely economic but borrowed from the political ascendency of Rome, tottered at every serious political crisis nearly in the same way as our very similar fabric of a paper currency. The great financial crisis, which in consequence of the Italo-Asiatic commotions of 664 f. set in upon the Roman capitalist- class, the bankruptcy of the state and of private persons, the general depreciation of landed property and of partnership-shares, can no longer be traced out in detail; but their general nature and their importance are placed beyond doubt by their results - the murder of the praetor by a band of creditors[32], the attempt to eject from the senate all the senators not free of debt[33], the renewal of the maximum of interest by Sulla[34] , the cancelling of 75 per cent of all debts by the revolutionary party[35] . The consequence of this system was naturally general impoverishment and depopulation in the provinces, whereas the parasitic population of migratory or temporarily settled Italians was everywhere on the increase.
In Asia Minor 80,000 men of Italian origin are said to have perished in one day[36]. How numerous they were in Delos, is evident from the tombstones still extant on the island and from the statement that 20,000 foreigners, mostly Italian merchants, were put to death there by command of Mithradates[37]. In Africa the Italians were so many, that even the Numidian town of Cirta could be defended mainly by them against Jugurtha[38]. Gaul too, it is said, was filled with Roman merchants; in the case of Spain alone - perhaps not accidentally - no statements of this sort are found. In Italy itself, on the other hand, the condition of the free population at this epoch had on the whole beyond doubt retrograded. To this result certainly the civil wars essentially contributed, which, according to statements of a general kind and but littletrustworthy, are alleged to have swept away from 100,000 to 150,000 of the Roman burgesses and 300,000 of the Italian population generally; but still worse was the effect of the economic ruin of the middle class, and of the boundless extent of the mercantile emigration which induced a great portion of the Italian youth to spend their most vigorous years abroad.
A compensation of very dubious value was afforded by the free parasitic Helleno-Oriental population, which sojourned in the capital as diplomatic agents for kings or communities, as physicians, schoolmasters, priests, servants, parasites, and in the myriad employments of sharpers and swindlers, or, as traders and mariners, frequented especially Ostia, Puteoli, and Brundisium.
Still more hazardous was the disproportionate increase of the multitude of slaves in the peninsula. The Italian burgesses by the census of 684 numbered 910,000 men capable of bearing arms, to which number, in order to obtain the amount of the free population in the peninsula, those accidentally passed over in the census, the Latins in the district between the Alps and the Po, and the foreigners domiciled in Italy, have to be added,
