The foundation walls, which Pliny and Livy enumerate among the wonders of Rome, have been, and are still being, discovered on the three sides of the hill which face the Piazza della Consolazione, the Piazza Montanara, and the Via di Torre de' Specchi. They are built of blocks of red tufa, with facing of travertine. The travertine facing is covered with inscriptions set up in honor of the great divinity of Rome by the kings and nations of the whole world. One cannot read these historical documents[49] without acquiring a new sense of the magnitude and power of the city. [Illustration: View of the Platform of the Temple of Jupiter.] These inscriptions are found mostly at the foot of the substructure, on the side towards the Piazza della Consolazione. The latest, found in the foundations of the Palazzo Moroni, contain messages of friendship and gratitude from kings Mithradates Philopator and Mithradates Philadelphos, of Pontus, from Ariobarzanes Philoromæus of Cappadocia and Athenais his queen, from the province of Lycia, from some townships of the province of Caria, etc. As for the remains of the temple itself, the colossal column discovered November 7, 1875, in the Conservatori garden, is not the only one saved from the wreck. Flaminio Vacca, the sculptor and amateur-archæologist of the sixteenth century, says: "Upon the Tarpeian Rock, behind the Palazzo de' Conservatori, several pillars of Pentelic marble (_marmo statuale_) were lately found. Their capitals are so enormous that out of one of them I have carved the lion now in the Villa Medici. The others were used by Vincenzo de Rossi to carve the prophets and other statues which adorn the chapel of cardinal Cesi in the church of S. Maria della Pace. I believe the columns belonged to the Temple of Jupiter. No fragments of the entablature were found: but as the building was so close to the edge of the Tarpeian Rock, I suspect they must have fallen into the plain." The correctness of this surmise is shown not only by the discovery of the dedicatory inscriptions, in the Piazza della Consolazione, just alluded to, but also from what took place in 1780, when the duca Lante della Rovere was excavating the foundations of a house, No. 13, Via Montanera. The discoveries are described by Montagnani as "marble entablatures of enormous size and beautiful workmanship, with festoons and _bucranii_ in the frieze. No one took the trouble to sketch them; they were destroyed on the spot. I have no doubt that they belonged to the temple seen by Vacca on the Monte Tarpeo, one hundred and eighty-six years ago." All these indications, compared with the discovery of the platform, the substructure, and the column of Pentelic marble in the Conservatori garden, leave no doubt as to the real position of the Temple of Jupiter. To that piece of marble we owe the opportunity and the privilege of settling a dispute on Roman topography which had lasted at least three centuries.
