In this survey of ancient cities I have not yet spoken of the great central city,--the City of the Seven Hills, to which all the world was tributary. Whatever was costly or rare or beautiful, in Greece or Asia or Egypt, was appropriated by her citizen kings, since citizens were provincial governors. All the great highways, from the Atlantic to the Tigris, converged to the capital,--all roads led to Rome; all the ships of Alexandria and Carthage and Tarentum, and other commercial capitals, were employed in furnishing her with luxuries or necessities. Never was there so proud a city as this "Epitome of the Universe." London, Paris, Vienna, Constantinople, St. Petersburg, Berlin, are great centres of fashion and power; but they are rivals, and excel only in some great department of human enterprise and genius, as in letters, or fashions, or commerce, or manufactures,--centres of influence and power in the countries of which they are capitals, yet they do not monopolize the wealth and energies of the world. London may contain more people than did ancient Rome, and may possess more commercial wealth; but London represents only the British monarchy, not a universal empire. Rome, however, monopolized every thing, and controlled all nations and peoples; she could shut up the schools of Athens, or disperse the ships of Alexandria, or regulate the shops of Antioch. What Lyons and Bordeaux are to Paris, Corinth and Babylon were to Rome,--mere dependent cities. Paul, condemned at Jerusalem, stretched out his arms to Rome, and Rome protected him. The philosophers of Greece were the tutors of Roman nobility. The kings of the East resorted to the palaces of Mount Palatine for favors or safety; the governors of Syria and Egypt, reigning in the palaces of ancient kings, returned to Rome to squander the riches they had accumulated. Senators and nobles took their turn as sovereign rulers of all the known countries of the world. The halls in which Darius and Alexander and Pericles and Croesus and Solomon and Cleopatra had feasted, became the witness of the banquets of Roman proconsuls. Babylon, Thebes, and Athens were only what Delhi and Calcutta are to the English of our day,--cities to be ruled by the delegates of the imperial Senate. Rome was the only "home" of the proud governors who reigned on the banks of the Thames, of the Seine, of the Rhine, of the Nile, of the Tigris. After they had enriched themselves with the spoils of the ancient monarchies they returned to their estates in Italy, or to their palaces on the Aventine. What a concentration of works of art on the hills, and around the Forum, and in the Campus Martius, and other celebrated quarters! There were temples rivalling those of Athens and Ephesus; baths covering more ground than the Pyramids, surrounded with Corinthian columns, and filled with the choicest treasures ransacked from the cities of Greece and Asia; palaces in comparison with which the Tuileries and Versailles are small;
