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?
