The establishment of the republic marked an era in the history of Rome. The people had decreed, as has been said, that for them there never should be a king, and the law was kept to the letter; though, if they meant that supreme authority should never be held among them by one man, it was violated many times. The story of Rome is unique in the history of the world, for it is not the record of the life of one great country, but of a city that grew to be strong and successfully established its authority over many countries. The most ancient and the most remote from the sea of the cities of Latium, Rome soon became the most influential, and began to combine in itself the traits of the peoples near it; but owing to the singular strength and rare impressiveness of the national character, these were assimilated, and the inhabitant of the capital remained distinctively a Roman in spite of his intimate association with men of different origin and training. The citizen of Rome was practical, patriotic, and faithful to obligation; he loved to be governed by inflexible law; and it was a fundamental principle with him that the individual should be subordinate to the state. His kings were either organizers, like Numa and Ancus Marcius, or warriors, like Romulus and Tullus Hostilius; they either made laws, like Servius, or they enforced them with the despotism of Tarquinius Superbus. It is difficult for us to conceive of such a majestic power emanating from a territory so insignificant. We hardly realize that Latium did not comprise a territory quite fifty miles by one hundred in extent, and that it was but a hundred miles from the Mediterranean to the Adriatic. It was but a short walk from Rome to the territory of the Etruscans, and when Tarquin found an asylum at Cære, he did not separate himself by twenty miles from the scene of his tyranny. Ostia was scarcely more distant, and one might have ridden before the first meal of the day to Lavinium, or Alba, or Veii, or to Ardea, the ancient city of the Rutuli. It is important to keep these facts in mind as we read the story of the remarkable city. All towns were built on hills in these early days, for safety in case of war, as well as because the valleys were insalubrious, but this is not a peculiarity of the Romans, for in New England in the late ages of our own ancestors they were obliged to follow the same custom. On the tops and slopes of seven hills, as they liked to remind themselves, the Romans built their city. They were not impressive elevations, though their sides were sharp and rocky, for the loftiest rose less than three hundred feet above the sea level. Their summits were crowned with groves of beech trees and oaks, and in the lower lands grew osiers and other smaller varieties.
