From the faint glimmerings of such doubtful and scattered lights, we should be inclined to believe, 1st, That (with every fair allowance for the differences of times and circumstances) the general income of the Roman provinces could seldom amount to less than fifteen or twenty millions of our money; 96 and, 2dly, That so ample a revenue must have been fully adequate to all the expenses of the moderate government instituted by Augustus, whose court was the modest family of a private senator, and whose military establishment was calculated for the defence of the frontiers, without any aspiring views of conquest, or any serious apprehension of a foreign invasion.
Notwithstanding the seeming probability of both these conclusions, the latter of them at least is positively disowned by the language and conduct of Augustus. It is not easy to determine whether, on this occasion, he acted as the common father of the Roman world, or as the oppressor of liberty; whether he wished to relieve the provinces, or to impoverish the senate and the equestrian order. But no sooner had he assumed the reins of government, than he frequently intimated the insufficiency of the tributes, and the necessity of throwing an equitable proportion of the public burden upon Rome and Italy. † In the prosecution of this unpopular design, he advanced, however, by cautious and well-weighed steps. The introduction of customs was followed by the establishment of an excise, and the scheme of taxation was completed by an artful assessment on the real and personal property of the Roman citizens, who had been exempted from any kind of contribution above a century and a half.
I. In a great empire like that of Rome, a natural balance of money must have gradually established itself. It has been already observed, that as the wealth of the provinces was attracted to the capital by the strong hand of conquest and power, so a considerable part of it was restored to the industrious provinces by the gentle influence of commerce and arts. In the reign of Augustus and his successors, duties were imposed on every kind of merchandise, which through a thousand channels flowed to the great centre of opulence and luxury; and in whatsoever manner the law was expressed, it was the Roman purchaser, and not the provincial merchant, who paid the tax. 97 The rate of the customs varied from the eighth to the fortieth part of the value of the commodity; and we have a right to suppose that the variation was directed by the unalterable maxims of policy; that a higher duty was fixed on the articles of luxury than on those of necessity, and that the productions raised or manufactured by the labor of the subjects of the empire were treated with more indulgence than was shown to the pernicious, or at least the unpopular commerce of Arabia and India. 98 There is still extant a long but imperfect catalogue of eastern commodities, which about the time of Alexander Severus were subject to the payment of duties; cinnamon, myrrh, pepper, ginger, and the whole tribe of aromatics a great variety of precious stones, among which the diamond was the most remarkable for its price, and the emerald for its beauty; 99 Parthian and Babylonian leather, cottons, silks, both raw and manufactured, ebony ivory, and eunuchs. 100 We may observe that the use and value of those effeminate slaves gradually rose with the decline of the empire.
II. The excise, introduced by Augustus after the civil wars, was extremely moderate, but it was general. It seldom exceeded one per cent.; but it comprehended whatever was sold in the markets or by public auction, from the most considerable purchases of lands and houses, to those minute objects which can only derive a value from their infinite multitude and daily consumption. Such a tax, as it affects the body of the people, has ever been the occasion of clamor and discontent. An emperor well acquainted with the wants and resources of the state was obliged to declare, by a public edict, that the support of the army depended in a great measure on the produce of the excise. 101
III. When Augustus resolved to establish a permanent military force for the defence of his government against foreign and domestic enemies, he instituted a peculiar treasury for the pay of the soldiers, the rewards of the veterans, and the extra-ordinary expenses of war. The ample revenue of the excise, though peculiarly appropriated to those uses, was found inadequate. To supply the deficiency, the emperor suggested a new tax of five per cent. on all legacies and inheritances. But the nobles of Rome were more tenacious of property than of freedom. Their indignant murmurs were received by Augustus with his usual temper. He candidly referred the whole business to the senate, and exhorted them to provide for the public service by some other expedient of a less odious nature. They were divided and perplexed. He insinuated to them, that their obstinacy would oblige him to propose a general land tax and capitation. They acquiesced in silence. 102. The new imposition on legacies and inheritances was, however, mitigated by some restrictions. It did not take place unless the object was of a certain value, most probably of fifty or a hundred pieces of gold; 103 nor could it be exacted from the nearest of kin on the father’s side. 104 When the rights of nature and poverty were thus secured, it seemed reasonable, that a stranger, or a distant relation, who acquired an unexpected accession of fortune, should cheerfully resign a twentieth part of it, for the benefit of the state. 105
Such a tax, plentiful as it must prove in every wealthy community, was most happily suited to the situation of the Romans, who could frame their arbitrary wills, according to the dictates of reason or caprice, without any restraint from the modern fetters of entails and settlements. From various causes, the partiality of paternal affection often lost its influence over the stern patriots of the commonwealth, and the dissolute nobles of the empire; and if the father bequeathed to his son the fourth part of his estate, he removed all ground of legal complaint. 106 But a rich childish old man was a domestic tyrant, and his power increased with his years and infirmities. A servile crowd, in which he frequently reckoned praetors and consuls, courted his smiles, pampered his avarice, applauded his follies, served his passions, and waited with impatience for his death. The arts of attendance and flattery were formed into a most lucrative science; those who professed it acquired a peculiar appellation; and the whole city, according to the lively descriptions of satire, was divided between two parties, the hunters and their game. 107 Yet, while so many unjust and extravagant wills were every day dictated by cunning and subscribed by folly, a few were the result of rational esteem and virtuous gratitude. Cicero, who had so often defended the lives and fortunes of his fellow-citizens, was rewarded with legacies to the amount of a hundred and seventy thousand pounds; 108 nor do the friends of the younger Pliny seem to have been less generous to that amiable orator. 109 Whatever was the motive of the testator, the treasury claimed, without distinction, the twentieth part of his estate: and in the course of two or three generations, the whole property of the subject must have gradually passed through the coffers of the state.
In the first and golden years of the reign of Nero, that prince, from a desire of popularity, and perhaps from a blind impulse of benevolence,
