Such was the constitution of the world-wide empire over which Augustus ruled as an absolute monarch with unlimited powers for forty-four years after the day of Actium. The frontier provinces were protected by standing armies, the members of which, collected from all countries and nationalities, had forsworn their native land and national spirit, and obeyed no orders but those of their military lord; the coasts were guarded by a well-manned fleet. On the Rhine eight legions (each consisting of 6100 foot and 726 horse) quartered in permanent camps, formed a strong bulwark against the Germans and kept Gaul under control; Spain was garrisoned by three legions; two were quartered in Africa, and an equal number watched over the safety of Egypt. Four legions maintained the supremacy of Rome in Syria and on the Euphrates; the Danubian provinces were guarded by six legions distributed through Mœsia, Pannonia, and Dalmatia. The eastern frontier being thus sufficiently protected by an army of occupation of 50,000 men, the banks of the Danube by a similar force of 70,000, and the Rhine district by 100,000; the fleets stationed in the harbours of Misenum, Ravenna, Forum Julii (Fréjus) and elsewhere kept the islands and maritime states under control and insured protection and security for commerce and traffic. [Illustration: ROMAN EMPEROR IN THE DRESS OF A GENERAL (Based on De Montfaucon)] A regular system of tolls and taxes brought the public revenue into good condition and filled the ærarium and fiscus; a vigilant police force and fire brigade, which Augustus distributed through the fourteen divisions of the capital, maintained tranquillity and order, protected life and property from evil-disposed and malicious persons, and curbed the outbreak of savage passions. Huge aqueducts, solidly constructed roads, stately buildings, temples and halls, aroused the admiration of contemporaries as of posterity. On the Field of Mars there arose a new and splendid city, composed of temples and halls, of public buildings for government purposes and for the amusements of the people, which excelled the glory of the City of the Seven Hills, “unique in character, unsurpassed in ancient or modern times,” so that Augustus could boast that he had found a city of brick and should leave a city of marble. In the provinces the improved government and administration of justice bred a condition of wealth and outward prosperity.
