But it was the conflict of gladiators which most deeply stimulated the passions of the people. The benches were crowded with eager spectators, and the voices of one hundred thousand were raised in triumph or rage as the miserable victims sank exhausted in the bloody sport. Yet it was not the gladiatorial sports of the amphitheatre which most strikingly attested the greatness and splendor of the city; nor the palaces, in which as many as four hundred slaves were sometimes maintained as domestic servants for a single establishment,--twelve hundred in number according to the lowest estimate, but probably five times as numerous, since every senator, every knight, and every rich man was proud to possess a residence which would attract attention; nor the temples, which numbered four hundred and twenty-four, most of which were of marble, filled with statues, the contributions of ages, and surrounded with groves; nor the fora and basilicas, with their porticos, statues, and pictures, covering more space than any cluster of public buildings in Europe, a mile and a half in circuit; nor the baths, nearly as large, still more completely filled with works of art; nor the Circus Maximus, where more people witnessed the chariot races at a time than are nightly assembled in all the places of public amusement in Paris, London, and New York combined,--more than could be seated in all the cathedrals of England and France.

No military review of modern times equalled those gorgeous triumphs, even as no scenic performance compares with the gladiatorial shows; the sun has never shone upon any human assemblage so magnificent and so grand, so imposing and yet so guilty. Not only were displayed the spoils of conquered kingdoms, and the triumphal cars of generals, but the whole military strength of the capital; an army of one hundred thousand men, flushed with victory, followed the gorgeous procession of nobles and princes. The triumph of Aurelian, on his return from the East, gives us some idea of the grandeur of that ovation to conquerors. "The pomp was opened by twenty elephants, four royal tigers, and two hundred of the most curious animals from every climate, north, south, east, and west. These were followed by sixteen hundred gladiators, devoted to the cruel amusement of the amphitheatre. Then were displayed the arms and ensigns of conquered nations, the plate and wardrobe of the Syrian queen. Then ambassadors from all parts of the earth, all remarkable in their rich dresses, with their crowns and offerings. Then the captives taken in the various wars,--Goths, Vandals, Samaritans, Alemanni, Franks, Gauls,
