We do not know how many private collections there were in Rome when the collectomania finally took the city by storm. A list of Roman collectors in the fashion of the modern work (_Ritz-Pacot_) would be most interesting and enlightening. However, judging from the statues and the public buildings we know to have been replete with objects of art, we gather that as an emporium of art Rome must have attained a magnitude unequalled in past or present times. Why this great collection of art did not transform the Romans into the most artistic people the world has ever seen, is a mystery only to be solved by hypothesis. Either the Romans were innately refractory to the refinements of true art, or, like to all _nouveaux riches_, the field of art merely afforded room for faddists, hobbyists and fashion seekers, and, only as sporadic cases, a few real lovers of good art. However this may be, without discussing the causes, the effect was certainly gigantic: art from every land found its way to Rome, which by force of circumstances thus became a monumental synthesis of art. Even at the time of Constantine, Rome counted 10 basilicas, 11 forums, 11 thermes, 18 aqueducts, 8 bridges, 37 city gates, 29 military roads leading to all parts of the known world, 2 arenas, 8 theatres, 2 circuses, 37 triumphal arches, 5 obelisks, 2 colossal statues, 22 equestrian statues, 423 temples with statues of the gods--eighty of these being in solid gold and seventy-seven in ivory. It is easy to understand that the above statistics only give a faint idea of the magnificence of Rome, for the 423 streets and 1790 private palaces noted in the same statistics as existing in Rome at the time of Constantine were in a measure respectively open-air museums and repositories of private collections of art, as no patrician mansion, according to Vitruvius, was complete without a place where paintings and objects of art could be exhibited with advantage. Cicero allows us a peep at the collections and gorgeous palaces owned by notable Romans as well as their style of living. In his oratio (_Pro Roscio Amerino_) he speaks of Chrysogon in these words: “Look at Chrysogon when he comes down from his fine mansion on the Palatine! He owns a charming villa, where he goes to rest, just at the gates of Rome. He also owns extensive domains, all magnificent and all near the city. His palace overflows with vases of Delos and Corinthian bronze. He keeps there the famous _authepsa_ bought by him some time ago at such a price that on hearing the auctioneer’s voice repeat the bid, the passers-by imagined a farm was being offered for sale. What shall we say of his chiselled silver? his precious stuffs? his paintings? statues? marbles? How many of such things do you think he owns? Just imagine what has been pillaged from so many opulent families in times of trouble and rapine; and all for the repletion of one single palace.”
