institutions, modifying, and in some cases changing, their native characters. The eastern half of the Empire, however, had been too thoroughly impregnated with the Greek element to yield easily to the new pressure; and accordingly while the Latin language spread among the barbarians of the west, Greek still continued to be the language of the East. This demarcation between the western or Latin-speaking and the eastern or Greek-speaking portions of the Empire became exceedingly important afterwards. Of this vast empire Rome was the metropolis, now a city of innumerable streets and buildings, and containing, it is calculated, a population of about two millions and a half. From Rome roads branched out in all directions leading to the other towns of Italy, and passing through the villa-studded estates of the rich Roman citizens. From the coasts of Italy, the Mediterranean afforded an easy access to the various provinces, by whose industry the metropolis and Italy itself were in a great measure supported. The provinces themselves were traversed by roads connecting town with town, and laying all parts of the Empire open to the civil and military functionaries of government. Usually residing at Rome, the will of the emperor vibrated through a hierarchy of intermediate functionaries, so as to be felt throughout the whole of his vast dominions. In effect, this will was absolute. In Augustus, as in Julius Cæsar, all the great offices of state, which had so long subsisted as mutual checks upon each other, were united, so as to confer on him power of the most unlimited description. The senate still met, but only as a judicial body in cases of treason, or legislatively to pass the decrees which Augustus had previously matured with a few private counselors; and the comitia were still held, but only to elect candidates already nominated by the emperor. In this system of absolute dominion in the hands of a single individual, the Romans cheerfully acquiesced, partly from experience of the superior nature of the government thus exercised to the wretched anarchy from which they had escaped, and partly in consequence of the hopelessness of revolt against a man who had the entire military force of the Empire at his disposal. In Rome and Italy, the public peace was preserved by the _prætorian cohorts_――bodies of soldiers of tried valor, to whom Augustus gave double pay. Throughout the provinces, the people were kept in check by the regular troops, who were accumulated, however, principally in the frontier provinces of the Empire, where they might both maintain tranquillity among the recently-conquered populations, and resist the attacks of the barbarian races beyond. The provinces where military force was required, Augustus retained in his own hands, administering them through legates appointed by himself, usually for several years; the others he intrusted to the senate, who named governors for a single year.
