But while neither an opulent urban middle class nor a strictly close body of capitalists grew up in Rome, it was constantly acquiring more and more the character of a great city. This is plainly indicated by the increasing number of slaves crowded together in the capital (as attested by the very serious slave conspiracy of 335), and still more by the increasing multitude of freedmen, which was gradually becoming inconvenient and dangerous, as we may safely infer from the considerable tax imposed on manumissions in 397[37] and from the limitation of the political rights of freedmen in 450[38]. For not only was it implied in the circumstances that the great majority of the persons manumitted had to devote themselves to trade or commerce, but manumission itself among the Romans was, as we have already said, less an act of liberality than an industrial speculation, the master often finding it more for his interest to share the profits of the trade or commerce of the freedman than to assert his title to the whole proceeds of the labour of his slave. The increase of manumissions must therefore have necessarily kept pace with the increase of the commercial and industrial activity of the Romans.
A similar indication of the rising importance of urban life in Rome is presented by the great development of the urban police. To this period probably belong in great measure the enactments under which the four aediles divided the city into four police districts, and made provision for the discharge of their equally important and difficult functions - for the efficient repair of the network of drains small and large by which Rome was pervaded, as well as of the public buildings and places; for the proper cleansing and paving of the streets; for obviating the nuisances of ruinous buildings, dangerous animals, or foul smells; for the removing of waggons from the highway except during the hours of evening and night, and generally for the keeping open of the communication; for the uninterrupted supply of the market of the capital with good and cheap grain; for the destruction of unwholesome articles, and the suppression of false weights and measures; and for the special oversight of baths, taverns, and houses of bad fame.
In respect to buildings the regal period, particularly the epoch of the great conquests, probably accomplished more than the first two centuries of the republic. Structures like the temples on the Capitol and on the Aventine and the great Circus were probably as obnoxious to the frugal fathers of the city as to the burgesses who gave their task-work; and it is remarkable that perhaps the most considerable building of the republican period before the Samnite wars, the temple of Ceres in the Circus, was a work of Spurius Cassius (261) who in more than one respect, sought to lead the commonwealth back to the traditions of the kings. The governing aristocracy moreover repressed private luxury with a rigour such as the rule of the kings, if prolonged, would certainly not have displayed. But at length even the senate was no longer able to resist the superior force of circumstances. It was Appius Claudius who in his epoch-making censorship (442) threw aside the antiquated rustic system of parsimonious hoarding, and taught his fellow-citizens to make a worthy use of the public resources. He began that noble system of public works of general utility, which justifies, if anything can justify, the military successes of Rome even from the point of view of the welfare of the nations, and which even now in its ruins furnishes some idea of the greatness of Rome to thousands on thousands who have never read a page of her history. To him the Roman state was indebted for its great military road, and the city of Rome for its first aqueduct. Following in the steps of Claudius, the Roman senate wove around Italy that network of roads and fortresses, the formation of which has already been described[39], and without which, as the history of all military states from the Achaemenidae down to the creator of the road over the Simplon shows, no military hegemony can subsist. Following in the steps of Claudius, Manius Curius built from the proceeds of the Pyrrhic spoil a second aqueduct for the capital (482); and some years previously (464) with the gains of the Sabine war he opened up for the Velino, at the point above Terni where it falls into the Nera, that broader channel in which the stream still flows, with a view to drain the beautiful valley of Rieti and thereby to gain space for a large burgess settlement along with a modest farm for himself. Such works, in the eyes of persons of intelligence, threw into the shade the aimless magnificence of the Hellenic temples.
The style of living also among the citizens now was altered. About the time of Pyrrhus silver plate began to make its appearance on Roman tables, and the chroniclers date the disappearance of shingle roofs in Rome from 470[40]. The new capital of Italy gradually laid aside its village-like aspect, and now began to embellish itself. It was not yet indeed customary to strip the temples in conquered towns of their ornaments for the decoration of Rome; but the beaks of the galleys of Antium were displayed at the orator's platform in the Forum[41] and on public festival days the gold-mounted shields brought home from the battle-fields of Samnium were exhibited along the stalls of the market[42]. The proceeds of fines were specially applied to the paving of the highways in and near the city, or to the erection and embellishment of public buildings. The wooden booths of the butchers, which stretched along the Forum on both sides, gave way, first on the Palatine side, then on that also which faced the Carinae, to the stone stalls of the money-changers; so that this place became the Exchange of Rome. Statues of the famous men of the past, of the kings, priests, and heroes of the legendary period, and of the Grecian hospes who was said to have interpreted to the decemvirs the laws of Solon; honorary columns and monuments dedicated to the great burgomasters who had conquered the Veientes, the Latins, the Samnites, to state envoys who had perished while executing their instructions, to rich women who had bequeathed their property to public objects, nay even to celebrated Greek philosophers and heroes such as Pythagoras and Alcibiades, were erected on the Capitol or in the Forum. Thus, now that the Roman community had become a great power, Rome itself became a great city.
Lastly Rome, as head of the Romano-Italian confederacy, not only entered into the Hellenistic state-system, but also conformed to the Hellenic system of moneys and coins. Up to this time the different communities of northern and central Italy, with few exceptions, had struck only a copper currency; the south Italian towns again universally had a currency of silver; and there were as many legal standards and systems of coinage as there were sovereign communities in Italy. In 485 all these local mints were restricted to the issuing of small coin; a general standard of currency applicable to all Italy was introduced, and the coining of the currency was centralized in Rome; Capua alone continued to retain its own silver coinage struck in the name of Rome, but after a different standard. The new monetary system was based on the legal ratio subsisting between the two metals, as it had long been fixed[43]. The common monetary unit was the piece of ten asses (which were no longer of a pound, but reduced to the third of a pound), the denarius, which weighed in copper 3 1/3 and in silver 1/72, of a Roman pound, a trifle more than the Attic drachma. At first copper money still predominated in the coinage; and it is probable that the earliest silver denarius was coined chiefly for Lower Italy and for intercourse with other lands. As the victory of the Romans over Pyrrhus and Tarentum and the Roman embassy to Alexandria could not but engage the thoughts of the contemporary Greek statesman, so the sagacious Greek merchant might well ponder as he looked on these new Roman drachmae. Their flat, unartistic, and monotonous stamping appeared poor and insignificant by the side of the marvellously beautiful contemporary coins of Pyrrhus and the Siceliots; nevertheless they were by no means, like the barbarian coins of antiquity, slavishly imitated and unequal in weight and alloy, but, on the contrary, worthy from the first by their independent and conscientious execution to be placed on a level with any Greek coin.
