us as the most ancient Christian cemetery in the world. The masonry of the vestibule is in the best style of Roman brickwork; and the frescoes on its walls, representing Christ and His apostles, the Good Shepherd, Orpheus, Elijah, etc., indicate a period of high artistic taste. This Catacomb contains the oldest representation extant of the Virgin and Child receiving the homage of the Wise men from the East, supposed to date from the end of the second century, and was often made use of in support of Roman Mariolatry. Several days might be profitably spent by the antiquarian in investigating the contents of the different tiers of galleries; while the geologist would find matter for interesting speculation in the partial intrusion of the older lithoid tufa here and there into the softer and more recent volcanic deposits in which the passages are excavated, and in which numerous decomposing crystals of leucite may be observed. On the same side of the way, farther on, is the Jewish Catacomb, the tombs of which bear Jewish symbols, especially the seven-branched golden candlestick, and are inscribed, not with the secular names and occupations of the occupants, but with their sacred names, as office-bearers of the synagogue, rulers, scribes, etc. The inscriptions are not in Hebrew, but in Greek letters. It is supposed that in this Catacomb were interred the bodies of the Jews who were banished to the valley of Egeria by Domitian.
About a quarter of a mile beyond the Catacombs you come to a descent, where there is a wide open space with a pillar in the centre, and behind it the natural rock of a peculiarly glowing red colour, overgrown with masses of ivy, wall-flower, and hawthorn just coming into blossom. Below the road, on the right, is a kind of piazza, shaded by a grove of funereal cypresses; and here is the church of St. Sebastian, one of the seven great basilicas which pilgrims visited to obtain the remission of their sins. It was founded by Constantine, on the site of the house and garden of the pious widow Lucina, who buried there the body of St. Sebastian after his martyrdom. This saint was a Gaulish soldier in the Roman army, who, professing Christianity, was put to death by order of Diocletian. The body of the saint is said to repose under one of the altars, marked by a marble statue of him lying dead, pierced with silver arrows, designed by Bernini. The present edifice was entirely rebuilt by Cardinal Scipio Borghese; and nothing remains of the ancient basilica save the six granite columns of the portico, which were in all likelihood taken from some old pagan temple. It was from the nave of this church that the only Catacomb which used to be visited by pilgrims was entered; all the other Catacombs which have since been opened being at that time blocked up and unknown. Indeed it was to the subterranean galleries under this church that the name of Catacomb was originally applied.
In the valley beneath St. Sebastian, on the left, is a large enclosure, covered with the greenest turf, and reminding one more, by its softness and compactness, of an English park than anything I had seen about Rome. Here are the magnificent ruins of what was long known as the Circus of Caracalla; but later investigations have proved that the circus was erected in honour of Romulus, the son of the Emperor Maxentius, in the year 311. It is the best preserved of all the ancient Roman circuses, and affords an excellent clue to the arrangements of such places for chariot races and the accommodation of the spectators. The external walls run on unbroken for about a quarter of a mile. In many places the vaults supporting the seats still remain. The spina in the centre marking the course of the races, on either end of which stood the two Egyptian obelisks which now adorn the Piazza Navona and the Piazza del Popolo, though grass-grown, can be easily defined; and the towers flanking the extremities, where the judges sat, and the triumphal gate through which the victors passed, are almost entire. It would not be difficult, with such aids to the imagination, to conjure up the splendid games that used to take place within that vast enclosure; the chariots of green, blue, white, and red driving furiously seven times round the course, the emperor and all his nobles sitting in the places of honour, looking on with enthusiasm, and the victor coming in at the goal, and the shouts and exclamations of the excited multitude. On the elevated ground behind the circus is a fringe of olive-trees, with a line of feathery elms beyond; and rising over all, the purple background of the Sabine and Alban hills. It is a lonely enough spot now; and the gentle hand of spring clothes the naked walls with a perfect garden of wild flowers, and softens with the greenest and tenderest turf the spots trodden by the feet of so many thousands. In the immediate vicinity of the circus are extensive ruins, visible and prominent objects from the road, consisting of large fragments of walls and apses, dispersed among the vineyards and enclosures.
By far the best-known monument on the Appian Way is the Tomb of Cæcilia Metella. It is a conspicuous landmark in the wide waste, and catches the eye at a long distance from many points of view. It is as familiar a feature in paintings of the Campagna almost as the Claudian Aqueduct. This celebrity it owes to its immense size, its wonderful state of preservation, and above all to the genius of Lord Byron, who has made it the theme of some of the most elegant and touching stanzas in Childe Harold. Nothing can be finer than the appearance of this circular tower in the afternoon, when the red level light of sunset, striking full upon it, brings out the rich warm glow of its yellow travertine stones in striking relief against the monotonous green of the Campagna. It is built on a portion of rising ground caused by a current of lava which descended from the Alban volcano during some prehistoric eruption, and stopped short here, forming the quarries on the left side of the road which supply most of the paving-stone of modern Rome. The Appian Way was here lowered several feet below the original level, in order to diminish the acclivity; and the mausoleum was consequently raised upon a substructure of unequal height corresponding with the inclination of the plane of ascent. It was originally cased with marble slabs, but these were stripped off during the middle ages for making lime; and Pope Clement XII. completed the devastation by removing large blocks which formed the basement, in order to construct the picturesque fountain of Trevi. A large portion of the Doric marble frieze, however, still remains, on which are sculptured bas-reliefs of rams' heads, festooned with garlands of flowers. Usually the bas-reliefs are supposed to represent bulls' heads; and the name of Capo de Bove (the "head of the ox"), by which the monument has long been known to the common people, is said to be derived from these ornaments. But a careful examination will convince any one that they are in reality rams' heads; and the vulgar name of the tomb was obviously borrowed from the armorial bearings of the Gaetani family, consisting of an ox's head, affixed prominently upon it when it served them as a fortress in the thirteenth century. Pope Boniface VIII., a member of this family, added the curious battlements at the top, which seem so slight and airy in comparison with the severe solidity of the rest of the structure, and are but a poor substitute for the massive conical roof which originally covered the tomb. Nature has done her utmost for nigh two thousand years to bring back this monument to her own bosom, but she has been foiled in all her attempts—the travertine blocks of its exterior, though fitted to each other without cement, being as smooth and even in their courses of masonry as when first constructed, and almost as free from weather-stains as if they had newly been taken from the quarry. Only on the broad summit, where medieval Vandals broke down the noble pile and desecrated it by their own inferior workmanship, has nature been able to effect a lodgment; and in the breaches of this fortress, which is but a thing of yesterday as compared with the monument, and yet is far more ruinous, she has planted bushes, trees, and thick festoons of ivy, as if laying her quiet finger upon the angry passions of man, and obliterating the memory of his evil deeds by her own fair and smiling growth.
The sepulchral vault in the interior was not opened till the time of Paul III., about 1540, when a beautiful marble sarcophagus, adorned with bas-reliefs of the chase, was found in it, which is supposed to be that which stands at the present day in the court of the Palazzo Farnese. This is likely to be true, for it is well known that this Pope, who was a member of the Farnese family, unscrupulously despoiled ancient Rome of many of its finest works of art in order to build and adorn his new palace. A golden urn containing ashes is said to have been discovered at the same time; but if so, it has long since disappeared. On a marble panel below the frieze an inscription in bold letters informs us that this is the tomb of Cæcilia Metella, daughter of Quintus Metellus—who obtained the sobriquet of Creticus for his conquest of Crete—and wife of Crassus. She belonged to one of the most haughty aristocratic families of ancient Rome, whose members at successive intervals occupied the highest positions in the state, and several of whom were decreed triumphs by the senate on account of their success in war. Her husband was surnamed Dives on account of his enormous wealth. He is said to have possessed a fortune equal to a million and a half pounds sterling; and
