either failed in the ordinary course of nature, or were extinguished in so many foreign and domestic wars, or, through a want of merit or fortune, insensibly mingled with the mass of the people. Very few remained who could derive their pure and genuine origin from the infancy of the city, or even from that of the republic, when Cæsar and Augustus, Claudius and Vespasian, created from the body of the senate a competent number of new Patrician families, in the hope of perpetuating an order, which was still considered as honorable and sacred. But these artificial supplies (in which the reigning house was always included) were rapidly swept away by the rage of tyrants, by frequent revolutions, by the change of manners, and by the intermixture of nations. Little more was left when Constantine ascended the throne, than a vague and imperfect tradition, that the Patricians had once been the first of the Romans. To form a body of nobles, whose influence may restrain, while it secures the authority of the monarch, would have been very inconsistent with the character and policy of Constantine; but had he seriously entertained such a design, it might have exceeded the measure of his power to ratify, by an arbitrary edict, an institution which must expect the sanction of time and of opinion. He revived, indeed, the title of Patricians, but he revived it as a personal, not as an hereditary distinction. They yielded only to the transient superiority of the annual consuls; but they enjoyed the pre-eminence over all the great officers of state, with the most familiar access to the person of the prince. This honorable rank was bestowed on them for life; and as they were usually favorites, and ministers who had grown old in the Imperial court, the true etymology of the word was perverted by ignorance and flattery; and the Patricians of Constantine were reverenced as the adopted Fathers of the emperor and the republic.

II. The fortunes of the Prætorian præfects were essentially different from those of the consuls and Patricians. The latter saw their ancient greatness evaporate in a vain title. The former, rising by degrees from the most humble condition, were invested with the civil and military administration of the Roman world. From the reign of Severus to that of Diocletian, the guards and the palace, the laws and the finances, the armies and the provinces, were intrusted to their superintending care; and, like the Viziers of the East, they held with one hand the seal, and with the other the standard, of the empire. The ambition of the præfects, always formidable, and sometimes fatal to the masters whom they served, was supported by the strength of the Prætorian bands; but after those haughty troops had been weakened by Diocletian, and finally suppressed by Constantine, the præfects, who survived their fall, were reduced without difficulty to the station of useful and obedient ministers. When they were no longer responsible for the safety of the emperor's person, they resigned the jurisdiction which they had hitherto claimed and exercised over all the departments of the palace. They were deprived by Constantine of all military command, as soon as they had ceased to lead into the field, under their immediate orders, the flower of the Roman troops; and at length, by a singular revolution, the captains of the guards were transformed into the civil magistrates of the provinces. According to the plan of government instituted by Diocletian, the four princes had each their Prætorian præfect; and after the monarchy was once more united in the person of Constantine, he still continued to create the same number of Four Præfects, and intrusted to their care the same provinces which they already administered. 1. The præfect of the East stretched his ample jurisdiction into the three parts of the globe which were subject to the Romans, from the cataracts of the Nile to the banks of the Phasis, and from the mountains of Thrace to the frontiers of Persia. 2. The important provinces of Pannonia, Dacia, Macedonia, and Greece, once acknowledged the authority of the præfect of Illyricum. 3. The power of the præfect of Italy was not confined to the country from whence he derived his title; it extended over the additional territory of Rhætia as far as the banks of the Danube, over the dependent islands of the Mediterranean, and over that part of the continent of Africa which lies between the confines of Cyrene and those of Tingitania. 4. The præfect of the Gauls comprehended under that plural denomination the kindred provinces of Britain and Spain, and his authority was obeyed from the wall of Antoninus to the foot of Mount Atlas.

After the Prætorian præfects had been dismissed from all military command, the civil functions which they were ordained to exercise over so many subject nations, were adequate to the ambition and abilities of the most consummate ministers. To their wisdom was committed the supreme administration of justice and of the finances, the two objects which, in a state of peace, comprehend almost all the respective duties of the sovereign and of the people; of the former, to protect the citizens who are obedient to the laws; of the latter, to contribute the share of their property which is required for the expenses of the state.
