FOLLOWING the Corso to its end at the Ripresa dei Barberi, and turning to the left, we find ourselves at once amid the remains of the Forum of Trajan, erected by the architect Apollodorus for the Emperor Trajan on his return from the wars of the Danube. This forum now presents the appearance of a ravine between the Capitoline and Quirinal, but is an artificial hollow, excavated to facilitate the circulation of life within the city. An inscription over the door of the column, which overtops the other ruins, shows that it was raised in order to mark the depth of earth which was removed to construct the forum. The earth was formerly as high as the top of the column, which reaches, 100 Roman feet, to the level of the Palatine Hill. The forum was sometimes called the "Ulpian," from one of the names of the emperor.
"Before the year A.D. 107 the splendours of the city and the Campus beyond it were still separated by a narrow isthmus, thronged perhaps by the squalid cabins of the poor, and surmounted by the remains of the Servian wall which ran along its summit. Step by step the earlier emperors had approached with their new forums to the foot of this obstruction. Domitian was the first to contemplate and commence its removal. Nerva had the fortune to consecrate and to give his own name to a portion of his predecessor's construction; but Trajan undertook to complete the bold design, and the genius of his architect triumphed over all obstacles, and executed a work which exceeded in extent and splendour any previous achievement of the kind. He swept away every building on the site, levelled the spot on which they had stood, and laid out a vast area of columnar galleries, connecting halls and chambers for public use and recreation. The new forum was adorned with two libraries, one for Greek, the other for Roman volumes, and it was bounded on the west by a basilica of magnificent dimensions. Beyond this basilica, and within the limits of the Campus, the same architect (Apollodorus) erected a temple for the worship of Trajan himself; but this work probably belonged to the reign of Trajan's successor, and no doubt the Ulpian forum, with all its adjuncts, occupied many years in building. The area was adorned with numerous statues, in which the figure of Trajan was frequently repeated, and among its decorations were groups in bronze or marble, representing his most illustrious actions. The balustrades and cornices of the whole mass of buildings flamed with gilded images of arms and horses. Here stood the great equestrian statue of the emperor; here was the triumphal arch decreed him by the senate, adorned with sculpture, which Constantine, two centuries later, transferred without a blush to his own, a barbarous act of this first Christian emperor, to which however we probably owe their preservation to this day from more barbarous spoliation."—Merivale, Romans under the Empire, ch. lxiii.
The beautiful Column of Trajan was erected by the senate and people of Rome, A.D. 114. It is composed of thirty-four blocks of marble, and is covered with a spiral band of bas-reliefs illustrative of the Dacian wars, and increasing in size as it nears the top, so that it preserves throughout the same proportion when seen from below. It was formerly crowned by a statue of Trajan, holding a gilt globe, which latter is still preserved in the Hall of Bronzes in the Capitol. This statue had fallen from its pedestal long before Sixtus V. replaced it by the existing figure of St. Peter. At the foot of the column was a sepulchral chamber, intended to receive the imperial ashes, which were however preserved in a golden urn, upon an altar in front of it.
"And apostolic statues climb
To crush the imperial urn, whose ashes slept sublime."
Childe Harold, cx.
It was while walking in this forum, that Gregory the Great, observing one of the marble groups which told of a good and great action of Trajan, lamented bitterly that the soul of so noble a man should be lost, and prayed earnestly for the salvation of the heathen emperor. He was told that the soul of Trajan should be saved, but that to ensure this he must either himself undergo the pains of purgatory for three days, or suffer earthly pain and sickness for the rest of his life. He chose the latter, and never after was in health. This incident is narrated by his three biographers, John and Paul Diaconus, and John of Salisbury.[50]
The forum of Trajan was partly uncovered by Pope Paul III. in the sixteenth century, but excavated in its present form by the French in 1812. There is much still buried under the streets and neighbouring houses.
"All over the surface of what once was Rome it seems to be the effort of Time to bury up the ancient city, as it were a corpse, and he the sexton; so that, in eighteen centuries, the soil over its grave has grown very deep, by the slow scattering of dust, and the accumulation of more modern decay upon older ruin.
"This was the fate, also, of Trajan's forum, until some papal antiquary, a few hundred years ago, began to hollow it out again, and disclosed the whole height of the gigantic column, wreathed round with bas-reliefs of the old emperor's warlike deeds (rich sculpture, which, twining from the base to the capital, must be an ugly spectacle for his ghostly eyes, if he considers that this huge, storied shaft must be laid before the judgment seat, as a piece of the evidence of what he did in the flesh). In the area before the column stands a grove of stone, consisting of the broken and unequal shafts of a vanished temple, still keeping a majestic order, and apparently incapable of further demolition. The modern edifices of the piazza (wholly built, no doubt, out of the spoil of its old magnificence) look down into the hollow space whence these pillars rise.
"One of the immense gray granite shafts lies in the piazza, on the verge of the area. It is a great, solid fact of the Past, making old Rome actually visible to the touch and eye; and no study of history, nor force of thought, nor magic of song, can so vitally assure us that Rome once existed, as this sturdy specimen of what its rulers and people wrought. There is still a polish remaining on the hard substance of the pillar, the polish of eighteen centuries ago, as yet but half rubbed off."—Hawthorne, Transformation.
On the north of this forum are two churches: that nearest to the Corso is Sta. Maria di Loreto (founded by the corporation of bakers in 1500), with a dome surmounted by a picturesque lantern by Giuliano di Sangallo, c. 1506. It contains a statue of Sta. Susanna (not the Susanna of the Elders) by Fiammingo (François de Quesnoy), which is justly considered the chef-d'œuvre of the Bernini School. The companion church is called Sta. Maria di Vienna, and (like Sta. Maria della Vittoria) commemorates the liberation of Vienna from the Turks in 1683, by Sobieski, king of Poland. It was built by Innocent XI.
