The name and use of the indictions, which serve to ascertain the chronology of the middle ages, were derived from the regular practice of the Roman tributes. The emperor subscribed with his own hand, and in purple ink, the solemn edict, or indiction, which was fixed up in the principal city of each diocese, during two months previous to the first day of September. And by a very easy connection of ideas, the word indiction was transferred to the measure of tribute which it prescribed, and to the annual term which it allowed for the payment. This general estimate of the supplies was proportioned to the real and imaginary wants of the state; but as often as the expense exceeded the revenue, or the revenue fell short of the computation, an additional tax, under the name of superindiction, was imposed on the people, and the most valuable attribute of sovereignty was communicated to the Prætorian præfects, who, on some occasions, were permitted to provide for the unforeseen and extraordinary exigencies of the public service. The execution of these laws (which it would be tedious to pursue in their minute and intricate detail) consisted of two distinct operations: the resolving the general imposition into its constituent parts, which were assessed on the provinces, the cities, and the individuals of the Roman world; and the collecting the separate contributions of the individuals, the cities, and the provinces, till the accumulated sums were poured into the Imperial treasuries. But as the account between the monarch and the subject was perpetually open, and as the renewal of the demand anticipated the perfect discharge of the preceding obligation, the weighty machine of the finances was moved by the same hands round the circle of its yearly revolution. Whatever was honorable or important in the administration of the revenue, was committed to the wisdom of the præfects, and their provincial. representatives; the lucrative functions were claimed by a crowd of subordinate officers, some of whom depended on the treasurer, others on the governor of the province; and who, in the inevitable conflicts of a perplexed jurisdiction, had frequent opportunities of disputing with each other the spoils of the people. The laborious offices, which could be productive only of envy and reproach, of expense and danger, were imposed on the Decurions, who formed the corporations of the cities, and whom the severity of the Imperial laws had condemned to sustain the burdens of civil society. The whole landed property of the empire (without excepting the patrimonial estates of the monarch) was the object of ordinary taxation; and every new purchaser contracted the obligations of the former proprietor. An accurate census, or survey, was the only equitable mode of ascertaining the proportion which every citizen should be obliged to contribute for the public service; and from the well-known period of the indictions, there is reason to believe that this difficult and expensive operation was repeated at the regular distance of fifteen years. The lands were measured by surveyors, who were sent into the provinces; their nature, whether arable or pasture, or vineyards or woods, was distinctly reported; and an estimate was made of their common value from the average produce of five years. The numbers of slaves and of cattle constituted an essential part of the report; an oath was administered to the proprietors, which bound them to disclose the true state of their affairs; and their attempts to prevaricate, or elude the intention of the legislator, were severely watched, and punished as a capital crime, which included the double guilt of treason and sacrilege. A large portion of the tribute was paid in money; and of the current coin of the empire, gold alone could be legally accepted. The remainder of the taxes, according to the proportions determined by the annual indiction, was furnished in a manner still more direct, and still more oppressive. According to the different nature of lands, their real produce in the various articles of wine or oil, corn or barley, wood or iron, was transported by the labor or at the expense of the provincials * to the Imperial magazines, from whence they were occasionally distributed for the use of the court, of the army, and of two capitals, Rome and Constantinople. The commissioners of the revenue were so frequently obliged to make considerable purchases, that they were strictly prohibited from allowing any compensation, or from receiving in money the value of those supplies which were exacted in kind. In the primitive simplicity of small communities, this method may be well adapted to collect the almost voluntary offerings of the people; but it is at once susceptible of the utmost latitude, and of the utmost strictness, which in a corrupt and absolute monarchy must introduce a perpetual contest between the power of oppression and the arts of fraud. The agriculture of the Roman provinces was insensibly ruined, and, in the progress of despotism which tends to disappoint its own purpose, the emperors were obliged to derive some merit from the forgiveness of debts, or the remission of tributes, which their subjects were utterly incapable of paying. According to the new division of Italy, the fertile and happy province of Campania, the scene of the early victories and of the delicious retirements of the citizens of Rome, extended between the sea and the Apennine, from the Tiber to the Silarus. Within sixty years after the death of Constantine, and on the evidence of an actual survey, an exemption was granted in favor of three hundred and thirty thousand English acres of desert and uncultivated land; which amounted to one eighth of the whole surface of the province. As the footsteps of the Barbarians had not yet been seen in Italy, the cause of this amazing desolation, which is recorded in the laws, can be ascribed only to the administration of the Roman emperors.
Either from design or from accident, the mode of assessment seemed to unite the substance of a land tax with the forms of a capitation. The returns which were sent of every province or district, expressed the number of tributary subjects, and the amount of the public impositions. The latter of these sums was divided by the former; and the estimate, that such a province contained so many capita, or heads of tribute; and that each head was rated at such a price, was universally received, not only in the popular, but even in the legal computation. The value of a tributary head must have varied, according to many accidental, or at least fluctuating circumstances; but some knowledge has been preserved of a very curious fact, the more important, since it relates to one of the richest provinces of the Roman empire, and which now flourishes as the most splendid of the European kingdoms. The rapacious ministers of Constantius had exhausted the wealth of Gaul, by exacting twenty-five pieces of gold for the annual tribute of every head. The humane policy of his successor reduced the capitation to seven pieces. A moderate proportion between these opposite extremes of extraordinary oppression and of transient indulgence, may therefore be fixed at sixteen pieces of gold, or about nine pounds sterling, the common standard, perhaps, of the impositions of Gaul. But this calculation, or rather, indeed, the facts from whence it is deduced, cannot fail of suggesting two difficulties to a thinking mind, who will be at once surprised by the equality, and by the enormity, of the capitation. An attempt to explain them may perhaps reflect some light on the interesting subject of the finances of the declining empire.
But this tax, or capitation, on the proprietors of land, would have suffered a rich and numerous class of free citizens to escape. With the view of sharing that species of wealth which is derived from art or labor, and which exists in money or in merchandise, the emperors imposed a distinct and personal tribute on the trading part of their subjects. Some exemptions, very strictly confined both in time and place, were allowed to the proprietors who disposed of the produce of their own estates. Some indulgence was granted to the profession of the liberal arts: but every other branch of commercial industry was affected by the severity of the law. The honorable merchant of Alexandria, who imported the gems and spices of India for the use of the western world; the usurer, who derived from the interest of money a silent and ignominious profit; the ingenious manufacturer, the diligent mechanic, and even the most obscure retailer of a sequestered village, were obliged to admit the officers of the revenue into the partnership of their gain; and the sovereign of the Roman empire, who tolerated the profession, consented to share the infamous salary, of public prostitutes. As this general tax upon industry was collected every fourth year, it was styled the Lustral Contribution: and the historian Zosimus laments that the approach of the fatal period was announced by the tears and terrors of the citizens, who were often compelled by the impending scourge to embrace the most abhorred and unnatural methods of procuring the sum at which their property had been assessed. The testimony of Zosimus cannot indeed be justified from the charge of passion and prejudice; but, from the nature of this tribute it seems reasonable to conclude, that it was arbitrary in the distribution, and extremely rigorous in the mode of collecting. The secret wealth of commerce, and the precarious profits of art or labor, are susceptible only of a discretionary valuation, which is seldom disadvantageous to the interest of the treasury; and as the person of the trader supplies the want of a visible and permanent security, the payment of the imposition, which, in the case of a land tax, may be obtained by the seizure of property, can rarely be extorted by any other means than those of corporal punishments. The cruel treatment of the insolvent debtors of the state, is attested, and was perhaps mitigated by a very humane edict of Constantine, who, disclaiming the use of racks and of scourges, allots a spacious and airy prison for the place of their confinement.
These general taxes were imposed and levied by the absolute authority of the monarch; but the occasional offerings of the coronary goldstill retained the name and semblance of popular consent. It was an ancient custom that the allies of the republic, who ascribed their safety or deliverance to the success of the Roman arms, and even the cities of Italy, who admired the virtues of their victorious general, adorned the pomp of his triumph by their voluntary gifts of crowns of gold, which after the ceremony were consecrated in the temple of Jupiter, to remain a lasting monument of his glory to future ages. The progress of zeal and flattery soon multiplied the number, and increased the size, of these popular donations; and the triumph of Cæsar was enriched with two thousand eight hundred and twenty-two massy crowns, whose weight amounted to twenty thousand four hundred and fourteen pounds of gold. This treasure was immediately melted down by the prudent dictator, who was satisfied that it would be more serviceable to his soldiers than to the gods: his example was imitated by his successors; and the custom was introduced of exchanging these splendid ornaments for the more acceptable present of the current gold coin of the empire. The spontaneous offering was at length exacted as the debt of duty; and instead of being confined to the occasion of a triumph, it was supposed to be granted by the several cities and provinces of the monarchy, as often as the emperor condescended to announce his accession, his consulship, the birth of a son, the creation of a Cæsar, a victory over the Barbarians, or any other real or imaginary event which graced the annals of his reign. The peculiar free gift of the senate of Rome was fixed by custom at sixteen hundred pounds of gold, or about sixty-four thousand pounds sterling. The oppressed subjects celebrated their own felicity, that their sovereign should graciously consent to accept this feeble but voluntary testimony of their loyalty and gratitude.
A people elated by pride, or soured by discontent, are seldom qualified to form a just estimate of their actual situation. The subjects of Constantine were incapable of discerning the decline of genius and manly virtue, which so far degraded them below the dignity of their ancestors; but they could feel and lament the rage of tyranny, the relaxation of discipline, and the increase of taxes. The impartial historian, who acknowledges the justice of their complaints, will observe some favorable circumstances which tended to alleviate the misery of their condition. The threatening tempest of Barbarians, which so soon subverted the foundations of Roman greatness, was still repelled, or suspended, on the frontiers. The arts of luxury and literature were cultivated, and the elegant pleasures of society were enjoyed, by the inhabitants of a considerable portion of the globe. The forms, the pomp, and the expense of the civil administration contributed to restrain the irregular license of the soldiers; and although the laws were violated by power, or perverted by subtlety, the sage principles of the Roman jurisprudence preserved a sense of order and equity, unknown to the despotic governments of the East. The rights of mankind might derive some protection from religion and philosophy; and the name of freedom, which could no longer alarm, might sometimes admonish, the successors of Augustus, that they did not reign over a nation of Slaves or Barbarians.
