Is it possible amid all these rapid changes to realise what Rome has been and is still? No, not on any of her seven hills, not in her streets, nor on her river embankments, not even in her churches, can this now be done. No: to realise the power and majesty of Ancient Rome one must go out into the Campagna, that desolate plain in which she lies. There, where the stupendous ruins of her great aqueducts stretch away in utter loneliness to the distant hills; there, where once a prosperous people dwelt in plenty, and where the only living things likely to be seen now are a statuesque goatherd and his nibbling flock—there, one may gather an idea of the might of ancient Rome. By Hadrian's Wall, which cuts the Borderland of England, one may do the same; and there are none of her ruined outposts, east or west, where her majesty is not more apparent than in the Eternal City herself.

Up on the Palatine, close to the trees that are seen in the sketch of the Clovis Victoriæ, the Etruscan wall of the first Rome is now in course of excavation. Up there, too, are the remains of the first wall of the Roman city built by Servius Tullius. In the Via Merulana part of a great earthwork with a moat outside can still be seen. Long after Carthage had been practically obliterated by her rival, Rome had extended so far, and attacks from outside became of so great a danger to the inhabitants, that Aurelian found it necessary to build a line of defence which the present walls might be said to occupy. From that time onwards the city grew steadily to a magnificence and power which has never been equalled. She ruled the known world. But it was not until Constantine the Great transferred himself and the seat of empire to Byzantium that the turning-point in her fortunes was reached. Well has the great emperor earned that proud title! From Milan he issued the decree which gave to the much persecuted Christians equal rights with other religions; and even went further, embracing the faith he had befriended.

Many churches lay claim to be the oldest foundation in Rome. S. Pudenziana is said to be the church S. Paul founded in the house of his Senator friend Pudens. Recent excavations under S. Clemente have brought to light early-Christian masonry beneath the Republican and Imperial remains, over which the present edifice stands. S. Prisca is another ancient church; and tradition attributes S. Giovanni in Laterano, S. Pietro, S. Paolo, S. Lorenzo, S. Croce in Gerusalemene, S. Agnese, and SS. Pietro e Marcellino to Constantine's era. The first four of these, with S. Maria Maggiore, were afterwards known as the Patriarchal Churches over which the Pope presided. With S. Croce and S. Sebastiano, they became the seven churches of Rome. In them the Pontiff celebrated High Mass; and they were the principal churches which drew pilgrims from throughout Christendom. In these seven the high altar presents its back to the congregation, for His Holiness celebrates Mass with his face to the worshippers. The Papal supremacy really owed its foundation to Gregory the Great. But it was not until two hundred years after his decease, when on Christmas Day of the year 800, Charlemagne was crowned by Leo III., that the "Holy Roman Empire" became an accomplished fact. Unfortunately for Ancient Rome the Carlovingian period was one of demolition and plunder. Christian zeal cared nought for the beauty of pagan buildings, and many an one was pulled down and a church erected with the material. It was later on however, in the time of the Renaissance, that columns and marble of every sort were used for the adornment of the numerous sacred edifices which sprang up. What was not wanted in construction was ground down to make lime. Banding iron, clamps, bronzes, and every description of metal that was found were thrown into furnaces and melted down. Nothing that could be made use of for building material was spared. The Church could never forget the persecution she had undergone, nor the thousands of martyrs who had died for the Faith. Is it a matter for surprise then—a surprise one must add mingled with great regret—that the glorious buildings of ancient Rome have almost disappeared?

Whichever of all Rome's churches was founded first, there is no disputing the fact that the huge fabric which occupies one side of the Piazza di S. Pietro is the most famous Christian edifice in the world. Bernini's best work, the grand colonnades on two sides of the square lead up in splendid curves to the great façade of S. Peter's. But, so great is the size of the building, so far set back the dome, that it is impossible to realise the immensity of either from any point of view in the piazza. The first church was founded in the year 90 at the place where so many martyrs had suffered death during the time of the tyrant Nero. The Emperor Constantine commenced afterwards the erection of a basilica on this spot, the façade of which Raphael has handed down in his fresco of the Incendio del Borgo. When Julian della Rovere became Pope Julius II., he wantonly ordered the destruction of the church as it then stood. This was done to make way for a greater with which his own name would be for ever connected; and he employed Bramante to design the new cathedral. Hands once more were laid on the buildings of ancient Rome and the construction was begun from its ruins. Except for some of the columns, the whole of the marble work of S. Peter's was, up to the commencement of last century, abstracted from the same source. Bramante's designs were never carried out. The many alterations to which they were subjected after his death led to great dissatisfaction, and in the end Michael Angelo was consulted. All he could do was to reserve as much as possible of the great architect's ground plan, and this is, except for the lengthening of the nave and the addition of the façade, as the great cathedral stands to-day.

The immense travertine columns of the façade form part of a portico which is over two hundred feet in length. Above the columns runs an inscription recording that it was put up by the Borghese Pontiff, Paul V. A balustrade, broken by pedestals, surmounts the cymatium; on the pedestals are extra-colossal figures of the Saviour (in the centre) and the Twelve Apostles. At either end are groups of barroque angels surrounding a circle over which is the Papal Mitre. In one of these circles there is a timepiece. The ceiling of the portico is a fine example of stucco work.

There are five doors which open into the building. The central is of bronze and one of the few things spared by the destroyer Julius when he demolished the old basilica. The doors next to this are those by which one enters the church. In March 1910 the old and very unhygienic leather flaps were removed, and glazed swing-doors have taken their place. The Porta Santa, or door at the north end of the portico, is walled up. It was only opened for the purpose of celebrating a Jubilee, and has been closed since 1825.

Many and repeated visits are necessary to S. Peter's before the size of the vast interior can be in any way grasped. It is only when one is accustomed to the scale of the little human figures walking about and their insignificance in proportion to the whole, that the immense height of even the Corinthian pilasters of the piers becomes apparent. The roof is vaulted, coffered and gilded. It is supported by four piers on each side of the nave. The floor is of coloured marble, and has the measurements of the great churches of Christendom let in with brass at the spot where each would end if measured from the east. Just inside the central bronze door is a slab of porphyry upon which the emperors were crowned. At the base of each pier, as well as in other parts of the church, the colossal statues of the founders of different religious Orders find a place. The last pier on the right has a bronze figure of S. Peter seated, one foot of which is partially worn away by the lips of devotees.

The dome grows upwards from four massive buttresses. Niches above their bases contain figures of SS. Longinus, Andrew, Helena, and Veronica, who holds the napkin with the impress of the Saviour's Face. Under the dome is the Confessio of S. Peter, to reach which a double flight of steps leads down. Eighty-nine lamps for ever burn on the balustrade which encloses the well of the entrance; and doors of gilded bronze shut off the niche in which the sarcophagus of the Apostle rests. Soaring high up on four bronze columns ninety-four feet from the floor, the great baldacchino rises above all. But so immense is the space under the dome that one has no idea of the height it attains. It was designed by Bernini, and is made partly of the bronze which covered the roof of the Pantheon.

Nothing at all can be said in praise of Bernini's design. The high altar, at which only the Pope celebrates mass, is above the Confessio and directly under the cross which forms the apex of this somewhat unsightly mass of metal. The interior decoration of the dome is not in any way striking. Above the four statues of the already enumerated saints are the loggie, containing the sacred relics of the lance which pierced the crucified Saviour's side, the head of S. Andrew, a portion of the Cross, and the "Volto-Santo"—the napkin or handkerchief of S. Veronica, which wiped the Lord's brow on the way to Calvary. Four mosaics of the Evangelists are beneath the frieze which carries the drum of the dome; and a series of four each are between the sixteen gilded ribs of the vaulting. In the tribune at the east end of the cathedral is the ancient wooden episcopal chair of S. Peter.
