The dissolute tyranny of Commodus, the civil wars occasioned by his death, and the new maxims of policy introduced by the house of Severus, had all contributed to increase the dangerous power of the army, and to obliterate the faint image of laws and liberty that was still impressed on the minds of the Romans. The internal change, which undermined the foundations of the empire, we have endeavored to explain with some degree of order and perspicuity. The personal characters of the emperors, their victories, laws, follies, and fortunes, can interest us no farther than as they are connected with the general history of the Decline and Fall of the monarchy. Our constant attention to that great object will not suffer us to overlook a most important edict of Antoninus Caracalla, which communicated to all the free inhabitants of the empire the name and privileges of Roman citizens. His unbounded liberality flowed not, however, from the sentiments of a generous mind; it was the sordid result of avarice, and will naturally be illustrated by some observations on the finances of that state, from the victorious ages of the commonwealth to the reign of Alexander Severus. The siege of Veii in Tuscany, the first considerable enterprise of the Romans, was protracted to the tenth year, much less by the strength of the place than by the unskilfulness of the besiegers. The unaccustomed hardships of so many winter campaigns, at the distance of near twenty miles from home, 81 required more than common encouragements; and the senate wisely prevented the clamors of the people, by the institution of a regular pay for the soldiers, which was levied by a general tribute, assessed according to an equitable proportion on the property of the citizens. 82 During more than two hundred years after the conquest of Veii, the victories of the republic added less to the wealth than to the power of Rome. The states of Italy paid their tribute in military service only, and the vast force, both by sea and land, which was exerted in the Punic wars, was maintained at the expense of the Romans themselves. That high-spirited people (such is often the generous enthusiasm of freedom) cheerfully submitted to the most excessive but voluntary burdens, in the just confidence that they should speedily enjoy the rich harvest of their labors. Their expectations were not disappointed. In the course of a few years, the riches of Syracuse, of Carthage, of Macedonia, and of Asia, were brought in triumph to Rome. The treasures of Perseus alone amounted to near two millions sterling, and the Roman people, the sovereign of so many nations, was forever delivered from the weight of taxes. 83 The increasing
