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.

The Temple of Apollo was by no means the only sacred museum of ancient Rome; there were scores of them, beginning with the Temple of Concord, so emphatically praised by Pliny. This temple, built by Camillus, at the foot of the Capitol, and restored by Tiberius and Septimius Severus, was still standing at the time of Pope Hadrian I. (772-795), when the inscription on its front was copied for the last time by the _Einsiedlensis_. It was razed to the ground towards 1450. "When I made my first visit to Rome," says Poggio Bracciolini, "I saw the Temple of Concord almost intact (_ædem fere integram_), built of white marble. Since then the Romans have demolished it, and turned the structure into a lime-kiln." The platform of the temple and a few fragments of its architectural decorations were discovered in 1817. The reader may appreciate the grace of these decorations, from a fragment of the entablature now in the portico of the Tabularium, and one of the capitals of the cella, now in the Palazzo dei Conservatori. The cella contained one central and ten side niches, in which eleven masterpieces of Greek chisels were placed, namely, the Apollo and Hera, by Baton; Leto nursing Apollo and Artemis, by Euphranor; Asklepios and Hygieia, by Nikeratos; Ares and Hermes, by Piston; and Zeus, Athena, and Demeter, by Sthennis. The name of the sculptor of the Concordia in the apse is not known. Pliny speaks also of a picture by Theodoros, representing Cassandra; of four elephants, cut in obsidian, a miracle of skill and labor, and of a collection of precious stones, among which was the sardonyx set in the legendary ring of Polykrates of Samos. Most of these treasures had been offered to the goddess by Augustus, moved by the liberality which Julius Cæsar had shown towards his ancestral goddess, Venus Genetrix. We know from Pliny, xxxv. 9, that Cæsar was the first to give due honor to paintings, by exhibiting them in his Forum Julium. He gave about $72,000 (eighty talents), for two works of Timomachos, representing Medea and Ajax. At the base of the Temple of Venus Genetrix he placed his own equestrian statue, the horse of which, modelled by Lysippos, had once supported the figure of Alexander the Great. The statue of Venus was the work of Arkesilaos, and her breast was covered with strings of British pearls. Pliny (xxxvii. 5), after mentioning the collection of gems made by Scaurus, and another made by Mithradates, which Pompey the Great had offered to Jupiter Capitolinus, adds: "These examples were surpassed by Cæsar the dictator, who offered to Venus Genetrix six collections of cameos and intaglios."
