Ancient guide-books of Rome, published in the middle of the fourth century,[34] mention four hundred and twenty-four temples, three hundred and four shrines, eighty statues of gods, of precious metal, sixty-four of ivory, and three thousand seven hundred and eighty-five miscellaneous bronze statues. The number of marble statues is not given. It has been said, however, that Rome had two populations of equal size, one alive, and one of marble. I have had the opportunity of witnessing or conducting the discovery of several temples, altars, shrines, and bronze statues. The number of marble statues and busts discovered in the last twenty-five years, either in Rome or the Campagna, may be stated at one thousand. Before beginning the description of these beautiful monuments, I must allude to some details concerning the management and organization of ancient places of worship, upon which recent discoveries have thrown a considerable, and in some cases, unexpected light. Roman temples, like the churches of the present day, were used not only as places of worship, but as galleries of pictures, museums of statuary, and "cabinets" of precious objects. In chapter v. of "Ancient Rome," I have given the catalogue of the works of art displayed in the temple of Apollo on the Palatine. The list includes: The Apollo and Artemis driving a quadriga, by Lysias; fifty statues of the Danaids; fifty of the sons of Egypt; the Herakles of Lysippos; Augustus with the attributes of Apollo (a bronze statue fifty feet high); the pediment of the temple, by Bupalos and Anthermos; statues of Apollo, by Skopas; Leto, by Kephisodotos, son of Praxiteles; Artemis, by Timotheos; and the nine Muses; also a chandelier, formerly dedicated by Alexander the Great at Kyme; medallions of eminent men; a collection of gold plate; another of gems and intaglios; ivory carvings; specimens of palæography; and two libraries.
