[ Capitolium adeo.... immutatum ut vineæ in senatorum subsellia successerint, stercorum ac purgamentorum receptaculum factum. Respice ad Palatinum montem..... vasta rudera.... cæteros colles perlustra omnia vacua ædificiis, ruinis vineisque oppleta conspicies, (Poggius, de Varietat. Fortunæ p. 21.)]
These relics are minutely described by Poggius, one of the first who raised his eyes from the monuments of legendary, to those of classic, superstition. [5] 1.Besides a bridge, an arch, a sepulchre, and the pyramid of Cestius, he could discern, of the age of the republic, a double row of vaults, in the salt-office of the Capitol, which were inscribed with the name and munificence of Catulus. 2. Eleven temples were visible in some degree, from the perfect form of the Pantheon, to the three arches and a marble column of the temple of Peace, which Vespasian erected after the civil wars and the Jewish triumph. 3. Of the number, which he rashly defines, of seven thermæ, or public baths, none were sufficiently entire to represent the use and distribution of the several parts: but those of Diocletian and Antoninus Caracalla still retained the titles of the founders, and astonished the curious spectator, who, in observing their solidity and extent, the variety of marbles, the size and multitude of the columns, compared the labor and expense with the use and importance. Of the baths of Constantine, of Alexander, of Domitian, or rather of Titus, some vestige might yet be found. 4. The triumphal arches of Titus, Severus, and Constantine, were entire, both the structure and the inscriptions; a falling fragment was honored with the name of Trajan; and two arches, then extant, in the Flaminian way, have been ascribed to the baser memory of Faustina and Gallienus. [501] 5. After the wonder of the Coliseum, Poggius might have overlooked small amphitheatre of brick, most probably for the use of the prætorian camp: the theatres of Marcellus and Pompey were occupied in a great measure by public and private buildings; and in the Circus, Agonalis and Maximus, little more than the situation and the form could be investigated. 6. The columns of Trajan and Antonine were still erect; but the Egyptian obelisks were broken or buried. A people of gods and heroes, the workmanship of art, was reduced to one equestrian figure of gilt brass, and to five marble statues, of which the most conspicuous were the two horses of Phidias and Praxiteles. 7. The two mausoleums or sepulchres of Augustus and Hadrian could not totally be lost: but the former was only visible as a mound of earth; and the latter, the castle of St. Angelo, had acquired the name and appearance of a modern fortress. With the addition of some separate and nameless columns, such were the remains of the ancient city; for the marks of a more recent structure might be detected in the walls, which formed a circumference of ten miles, included three hundred and seventy-nine turrets, and opened into the country by thirteen gates.

This melancholy picture was drawn above nine hundred years after the fall of the Western empire, and even of the Gothic kingdom of Italy. A long period of distress and anarchy, in which empire, and arts, and riches had migrated from the banks of the Tyber, was incapable of restoring or adorning the city; and, as all that is human must retrograde if it do not advance, every successive age must have hastened the ruin of the works of antiquity. To measure the progress of decay, and to ascertain, at each æra, the state of each edifice, would be an endless and a useless labor; and I shall content myself with two observations, which will introduce a short inquiry into the general causes and effects. 1. Two hundred years before the eloquent complaint of Poggius, an anonymous writer composed a description of Rome. [6] His ignorance may repeat the same objects under strange and fabulous names. Yet this barbarous topographer had eyes and ears; he could observe the visible remains; he could listen to the tradition of the people; and he distinctly enumerates seven theatres, eleven baths, twelve arches, and eighteen palaces, of which many had disappeared before the time of Poggius. It is apparent, that many stately monuments of antiquity survived till a late period, [7] and that the principles of destruction acted with vigorous and increasing energy in the thirteenth and fourteenth centuries. 2. The same reflection must be applied to the three last ages; and we should vainly seek the Septizonium of Severus; [8] which is celebrated by Petrarch and the antiquarians of the sixteenth century. While the Roman edifices were still entire, the first blows, however weighty and impetuous, were resisted by the solidity of the mass and the harmony of the parts; but the slightest touch would precipitate the fragments of arches and columns, that already nodded to their fall.
