For many centuries the rule of Rome changed the geography, changed the subject peoples, changed the power, changed civil society. From the Seven hills and marshes of the Capitol to the hegemony over the known world. From the rough shepherds of Latium to Julius Caesar. From the furrow torn between Romulus and Remus to the majesty of the Roman law. So Rome changed and Rome with the Romans. And the world. All this led Rome, for several centuries, to not be content with what it had achieved. Until the decline of morals and the conquest of the known world made its unlimited borders vulnerable.
