Let us now turn our attention to more imposing structures. The first temple in the excavation of which I took part was that of Jupiter Optimus Maximus on the Capitoline Hill.[48] Its discovery was due more to an intuition of the truth, than to actual recognition of existing remains. On November 7, 1875, while digging for the foundation of the new Rotunda in the garden which divides the Conservatori palace from that of the Caffarellis,--the residence of the German ambassador,--our workmen came upon a piece of a colossal fluted column of Pentelic marble, lying on a platform of squared stones, which were laid without mortar, in a decidedly archaic style. Were we in the presence of the remains of the famous Capitolium, or of one of the smaller temples within the Arx? To give this query a satisfactory answer, we must remember that the Capitoline Hill had two summits, one containing the citadel, or Arx, the other the Temple of Jupiter Optimus Maximus, the Capitolium. Ancient writers never use the two names promiscuously, or apply them indifferently to either summit or to the whole hill. The name of the hill is the _Capitoline_; not the _Capitol_, which means exclusively the portion occupied by the great temple. Suffice it to quote Livy's evidence (vi. 20), _ne quis in Arce aut Capitolio habitaret_, and also the passage of Aulus Gellius (v. 12) in which the shrine of Vedjovis is placed between the Arx and the Capitolium. For many generations topographers tried to discover which summit was occupied by the citadel, and which by the temple. The Italian school, save a few exceptions, had always identified the site of the Aracœli with that of the temple, the Caffarelli palace with that of the citadel. The Germans upheld the opposite theory. In these circumstances it is not surprising that the discovery made November 7, 1875, should have excited us; because we saw at once our chance of settling the dispute, not theoretically, but with the evidence of facts. The Temple of Jupiter Optimus Maximus, designed by Tarquinius Priscus, built by Tarquinius Superbus, and dedicated in 509 B. C. by the consul M. Horatius Pulvillus, stood on a high platform 207½ feet long, by 192½ feet broad. The front of the edifice, ornamented with three rows of columns, faced the south. The style of the architecture was purely Etruscan, and the intercolumniations were so wide as to require architraves of timber. The cella was divided into three sections, the middle one of which was sacred to Jupiter, that on the right to Minerva, that on the left to Juno Regina; the top of the pediment was ornamented with a terra-cotta quadriga. Of the same material was the statue of the god, with the face painted red, and the body dressed in a _tunica palmata_ and a _toga picta_, the work of an Etruscan artist, Turianus of Fregenæ.
