spacious streets, eighty golden statues of the gods; sixty-six large ivory statues of the gods; forty-six thousand six hundred and three houses; seventeen thousand and ninety-seven palaces; thirteen thousand and fifty-two fountains; three thousand seven hundred and eighty-five bronze statues of emperors and generals; twenty-two great horses in bronze; two colossi; two spiral columns; thirty-one theatres; eleven amphitheatres; nine thousand and twenty-six baths; two thousand three hundred shops of perfumers; two thousand and ninety-one prisons. [Footnote: St. Ampere, _Hist. Romaine a Rome_.] This seems to be incredible. "But," says Story, "Augustus divided the city into eighteen regions: each region contained twenty-two vici; each vicus contained about two hundred and thirty dwelling-houses, so that there must have been seventy-five thousand houses; of these houses, seventeen thousand were palaces, or domus. If each contained two hundred persons, (and four hundred slaves were maintained in a single palace,) reckoning family, freedmen, and slaves, we have three millions four hundred thousand people, and supposing the remaining fifty-eight thousand houses to have contained twenty-five persons each, we have in them one million four hundred and fifty thousand, which would give an entire population of four millions eight hundred and fifty thousand." If Mr. Merivale's estimate of seven hundred thousand is correct, then the Colosseum would hold nearly one in six of the whole population, which is incredible. Indeed, it is probable that even four millions was under than above the true estimate, which would make Rome the most populous city ever seen upon our globe. Nor is it extravagant to suppose this. The city numbered, according to the census, eighty thousand people in the year 197; and in 683 it had risen to four hundred and fifty thousand. Is it strange it should have numbered four millions in the time of Augustus, or even six millions in the time of Arelian, when we bear in mind that it was the political and social centre of a vast empire, and that empire the world? If London contains three millions at the present day, and Paris two millions, why should not a capital which had no rival, and which controlled at least one hundred and twenty millions of people? So that Pliny was not probably wrong when he said, "_Si quis altitudinem tectorum addat, dignam profecto oestimationem concipiat, fateatur qui nullius urbis magnitudinem potuisse ei comparare._" "If any one considers the height of the roofs, so as to form a just estimate, he will confess that no city could be compared with it for magnitude."
