Beside the passages of the "Hadrian's Life," and of Dion Cassius, two descriptions of the monument have come down to us, one by Procopius, the other by Leo I. From these we learn that it was composed of a square basement of moderate height, each side of which measured 247 feet. It was faced with blocks of Parian marble, with pilasters at the corners, crowned by a capital. Above the pilasters were groups of men and horses in bronze, of admirable workmanship. The basement was protected around by a sidewalk and a railing of gilt bronze, supported by marble pillars crowned with gilded peacocks, two of which are in the Giardino della Pigna, in the Vatican. A grand circular mole, nearly a thousand feet in circumference, and also faced with blocks of Parian marble, stood on the square basement and supported in its turn a cone of earth covered with evergreens, like the mausoleum of Augustus.
Of this magnificent decoration nothing now remains except a few blocks of the coating of marble, on the east side of the quadrangle, near the Bastione di S. Giovanni. All that is visible of the ancient work from the outside are the blocks of peperino of the mole which once supported the outer casing. The rest, both above and below, is covered by the works of fortification constructed at various periods, from the time of Honorius (393-403) to our own days. In no other monument of ancient and medieval Rome is our history written, molded, as it were, so vividly, as upon the battered remains of this castle-tomb. Within and around it took place all the fights for dominion with which popes, emperors, barons, barbarians, Romans, have distracted the city for fifteen hundred years.
Of the internal arrangement of the monument nothing was known until 1825, when the principal door was discovered in the middle of the square basement facing the bridge. It opens upon a corridor leading to a large niche, which, it is conjectured, contained a statue of Hadrian. The walls of this vestibule, by which modern visitors generally begin their inspection, are built of travertine, and bear evidence of having been paneled with Numidian marble. The pavement is of white mosaic. On the right side of this vestibule, near the niche, begins an inclined spiral way, 30 feet high and 11 feet wide, leading up to the central chamber, which is in the form of a Greek cross.
There is no doubt that the tomb was adorned with statues. Procopius distinctly says that, during the siege laid by the Goths to the castle in 537, many of them were hurled down from the battlements upon the assailants. On the strength of this passage topographers have been in the habit of attributing to the mausoleum all the works of statuary discovered in the neighborhood; like the Barberini Faun now in Munich, the exquisite statue of a River God described by Cassiano dal Pozzo, etc., as if such subjects were becoming a house of death. The mausoleum of Hadrian formed part of one of the largest and noblest cemeteries of ancient Rome, crossed by the Via Triumphalis. The tomb next in importance to it was the so-called "Meta," or "sepulcrum Romuli," or "sepulcrum Neronis," a pyramid of great size, which stood on the site of the church of St. Maria Transpontina, and was destroyed by Alexander VI. in 1499.
TRAJAN'S FORUM[13]
BY FRANCIS WEY
In the midst of the busy quarters lying at the base of the Quirinal, you come out upon a great piazza which you name at once without ever having seen it before; Trajan's Column serves as ensign for a forum, of which Apollodorus of Damascus erected the porticoes. The lines described by the bases of a plantation of pillars will help you to identify the pesimeter of the temple which Hadrian consecrated, and the site of the Ulpian Library which was divided into two chambers—one for Greek books, and the other for Latin; and finally the situation of the basilica, opening on to the forum and with its apse in the north-northwest direction....
It was in the Ulpian Basilica that, in 312, Constantine, having assembled the notables of the empire seated himself in the presbyterium, to proclaim his abjuration of polytheism in favor of the religion of Christ; on that day and spot the prince closed the cycle of antiquity, opened the catacombs, and inaugurated the modern world. The Acts of St. Sylvester describe many passages of the discourse in which, "invoking truth against mischievous divisions," and declaring that he "put away superstitions born of ignorance and reared on unreason," the emperor ordains that "churches be opened to Christians, and that the priests of the temples and those of Christ enjoy the same privileges." He himself undertakes to build a church in his Lateran palace.
I do not think there exists any monument in the world more precious or more exquisite in its proportions than Trajan's Column, nor one that has rendered more capital service. This has been set forth with more authority than I can pretend to, by Viollet-le-Duc, the architect who has written best on his own art; his description sums up the subject and makes everything clear. A set of pictures of the campaigns of Trajan against the Decians—the bas-reliefs—reproduces the arms, the accouterments, the engines of war, the dwellings of the barbarians; we discern the breed of the warriors and their horses; we look upon the ships of the time, canoes and quinqueremes; women of all ranks, priests of all theogonies, sieges, and assaults. Such are the merits of this sculptured host, that Polidoro da Caravaggio, Giulio Romano, Michael Angelo, and all the artists of the Renaissance have drawn thence models of style and picturesque grouping.
