The Romans, by the fall of Tarentum, were now the undisputed masters of Italy, and had made the first great step towards the conquest of the world. The city of Romulus was now four hundred and eighty years old, and the national domain extended from the Ciminian wood in Etruria to the middle of the Campania. It was called the Ager Romanus, in which was a population of two hundred and ninety-three thousand men capable of bearing arms; and the citizens of the various conquered cities, who had served certain magistracies in them, were enrolled among Roman citizens, with all the rights to which the citizens of the capital were entitled,-- absolute authority over wife, children, and slaves, security from capital punishment except by a vote of the people, or under military authority in the camp, access to all the honors and employments of the state, the right of suffrage, and the possession of Quirinal property. They felt themselves to be allies of Rome, and henceforward lent efficient aid in war. To all practical intents, they were Romans as completely as the inhabitants of Marseilles are French. Tarentum, Neapolis, Tibur, Praeneste, and other large cities, enjoyed peculiar privileges; but armed garrisons were maintained in them, under the form of colonies. The administration of them was organized after the model of Rome. Military roads were constructed between all places of importance. [Sidenote: The virtues of eminent Patricians.] The same sterling virtues which characterized the absolute rule of the Patricians still continued, and patriotism partook of the nature of religious sentiment. Three Decii surrendered their lives for the Roman army, and Manlius immolated his son to the genius of discipline; Runnus is degraded from the Senate for possessing ten pounds of silver plate, although twice consul and once dictator; Regulus, twice consul, possessed no more than one little field in the barren district of Papinice. Curius like Fabricius prepared his simple meal with his own hand, and refused the gold of the Samnites, as Fabricius refused that of Pyrrhus. The new masters of Italy deserved their empire. There was union because there was now political equality. The "new men, like Fabricius and Curius Dentatus, were not less numerous in the Senate than the old Curial families. The aristocracy of blood was blended with the aristocracy of merit. The consulship gave unity of command, the Senate wisdom and the proper strength, preserving a happy equilibrium of forces,--the combination of royalty, aristocracy, and democracy, which, with military virtues and austere manners, made an irresistible force." [Footnote: Durny, _Hist. des Romains_] This period, the fifth century of the existence of the Roman state, was its heroic age. [Sidenote: Rome prepares for aggressive and unjust war.]
