Obelisk of Rameses the Great.

The second work, discovered June 17, was an obelisk which was wonderfully well preserved to the very top of the pinnacle, and covered with hieroglyphics. It was quarried at Assuan, from a richly colored vein of red granite, and was brought to Rome, probably under Domitian, together with the obelisk now in the Piazza del Pantheon. The two monoliths are almost identical in size and workmanship, and are inscribed with the same cartouches of Rameses the Great. The one which I discovered was set up, in 1887, to the memory of our brave soldiers who fell at the battle of Dogali. The site selected for the monument, the square between the railway station and the Baths of Diocletian, is too large for such a comparatively small shaft.

Two days later, on the 19th, we discovered two kynokephaloi or kerkopithekoi, five feet high, carved in black porphyry. The monsters are sitting on their hind legs, with the paws of the forearms resting on the knees. Their bases contain finely-cut hieroglyphics, with the cartouche of King Necthor-heb, of the thirtieth Sebennitic dynasty. One of these kynokephaloi, and also the obelisk, were certainly seen in 1719 by the masons who built the foundations of the Biblioteca Casanatense. For some reason unknown to us, they kept their discovery a secret. Many other works of art were discovered before the close of the excavations, in the last days of June. Among them were a crocodile in red granite, the pedestal of a candelabrum, triangular in shape, with sphinxes at the corners; a column of the temple, with reliefs representing an Isiac procession; and a portion of a capital. From an architectural point of view, the most curious discovery was that the temple itself, with its colonnades and double cella, had been brought over, piece by piece, from the banks of the Nile to those of the Tiber. It is not an imitation; it is a purely original Egyptian structure, shaded first by the palm-trees of Saïs, and later by the pines of the Campus Martius.

The earliest trustworthy account we have of its existence is given by Flavius Josephus. He relates how Tiberius, after the assault of Mundus against Paulina,[53] condemned the priests to crucifixion, burned the shrine, and threw the statue of the goddess into the Tiber. Nero restored the sanctuary; it was, however, destroyed again in the great conflagration, a. d. 80. Domitian was the second restorer; Hadrian, Commodus, Caracalla, and Alexander Severus improved and beautified the group, from time to time. At the beginning of the fourth century of our era it contained the propylaia, or pyramidal towers with a gateway, at each end of the dromos; one near the present church of S. Stefano del Cacco, one near the church of S. Macuto. They were flanked by one or more pairs of obelisks, of which six have been recovered up to the present time, namely, one now in the Piazza della Rotonda, a second in the Piazza della Minerva, a third in the Villa Mattei, a fourth in the Piazza della Stazione, a fifth in the Sphæristerion at Urbino, and fragments of a sixth in the Albani collection.

From the propylaia, a dromos, or sacred avenue, led to the double temple. To the dromos belong the two lions in the Museo Etrusco Gregoriano, the two lions in the Capitoline Museum, the sphinx of Queen Hathsèpu in the Barracco collection, the sphinx of Amasis and the Tranquilli sphinx in the Capitol, the cow Hathor and the statue of Uahábra in the Museo Archeologico in Florence, the kynokephaloi of Necthor-heb, the kynokephalos which gave the popular name of Cacco (ape) to the church of S. Stefano, the statue formerly in the Ludovisi Gallery, the Nile of the Braccio Nuovo, the Tiber of the Louvre, the Oceanus at Naples, the River-God buried in 1440, the Isiac altars of the Capitol and of the Louvre, the tripod, the crocodile and sundry other fragments which were found in 1883. Of the temple itself we possess two columns covered with mystic bas-reliefs, seven capitals,—one in the Capitol, the others in the Vatican,—and two blocks of granite from the walls of the cella, one in the Barberini gardens, one in the Palazzo Galitzin.

The last historical mention we possess of this admirable Egyptian museum of ancient Rome was found by Delille in the "Cod. Parisin." 8064, in which the attempt by Nicomachus Flavianus to revive the pagan religion in 394 a. d. is minutely described.[54] The reaction caused by this final outburst of fanaticism must have been fatal to the temple. The masterpieces of the dromos were upset, and otherwise damaged, the faces of the kynokephaloi and the noses and paws of the sphinxes were knocked off, and statues of Pharaohs, gods, priests, dignitaries, and Pastophoroi were hurled from their pedestals, and broken to pieces. When this wholesale destruction took place, the pavement of the temple was still clear of the rubbish and loose soil. The sphinx of Amasis, found June 14, was lying on its left side on the bare pavement; the two apes had fallen on their backs. No attempt, however, was made to overthrow the obelisks, at least the one which I discovered. When the monolith fell, in the eighth or ninth century, the floor of the Iseum was already covered with a bed of rubbish five feet thick. To this fact we owe the wonderful preservation of the obelisk, the soft, muddy condition of the soil having eased the weight of the fall.

Students have wondered at the existence, in our time, of such a mine of antiquities in this quarter of the Campus Martius, where it appears as if, in spite of the feverish search for ancient marbles, this spot had escaped the attention of the excavators of the past four or five centuries. It did not escape their attention. The whole area of the Iseum, save a few recesses, has been explored since the Middle Ages, but the search was made to secure marble, which could be burnt into lime, or turned into new shapes. Of what use would porphyry, or granite, or basalt be for such purposes? These materials are useless for the lime-kiln, and too hard to be worked anew, and accordingly they were left alone. In the excavations of 1883 I found the best evidence that such was the case. The obelisk is of granite; its pedestal of white marble. The obelisk escaped destruction, but the pedestal was split, and made ready for the lime-kiln.

The Temple of Neptune. The discoveries made in 1878 in the Piazza di Pietra, on the site of the Temple of Neptune, rank next in importance to those just described. In repairing a drain which runs through the Via de' Bergamaschi to the Piazza di Pietra, the foundations of an early mediæval church, dedicated to S. Stephen (Santo Stefano del Trullo) were unearthed, together with historical inscriptions, pieces of columns of giallo antico, and other architectural fragments. On a closer examination of the discoveries, I was able to ascertain that the whole church had been built with spoils from the triumphal arch of Claudius in the Piazza di Sciarra, and from the Temple of Neptune in the Piazza di Pietra. To enable the reader to appreciate the value of the discovery, I must begin with a short description of the temple itself.
