and inheritances; and during his reign (for the ancient proportion was restored after his death) he crushed alike every part of the empire under the weight of his iron sceptre.

When all the provincials became liable to the peculiar impositions of Roman citizens, they seemed to acquire a legal exemption from the tributes which they had paid in their former condition of subjects. Such were not the maxims of government adopted by Caracalla and his pretended son. The old as well as the new taxes were, at the same time, levied in the provinces. It was reserved for the virtue of Alexander to relieve them in a great measure from this intolerable grievance, by reducing the tributes to a thirteenth part of the sum exacted at the time of his accession. It is impossible to conjecture the motive that engaged him to spare so trifling a remnant of the public evil; but the noxious weed, which had not been totally eradicated, again sprang up with the most luxuriant growth, and in the succeeding age darkened the Roman world with its deadly shade. In the course of this history, we shall be too often summoned to explain the land tax, the capitation, and the heavy contributions of corn, wine, oil, and meat, which were exacted from the provinces for the use of the court, the army, and the capital.

As long as Rome and Italy were respected as the centre of government, a national spirit was preserved by the ancient, and insensibly imbibed by the adopted, citizens. The principal commands of the army were filled by men who had received a liberal education, were well instructed in the advantages of laws and letters, and who had risen, by equal steps, through the regular succession of civil and military honors. To their influence and example we may partly ascribe the modest obedience of the legions during the two first centuries of the Imperial history.

But when the last enclosure of the Roman constitution was trampled down by Caracalla, the separation of professions gradually succeeded to the distinction of ranks. The more polished citizens of the internal provinces were alone qualified to act as lawyers and magistrates. The rougher trade of arms was abandoned to the peasants and barbarians of the frontiers, who knew no country but their camp, no science but that of war no civil laws, and scarcely those of military discipline. With bloody hands, savage manners, and desperate resolutions, they sometimes guarded, but much oftener subverted, the throne of the emperors.
