In fact, the Basilica of Constantine existed no longer, while that of Michael Angelo, the masterpiece of thirty popes, which cost the labour of three centuries and the expense of two hundred and sixty millions, existed not yet. The ancient edifice, which had lasted for eleven hundred and forty-five years, had been threatening to fall in about 1440, and Nicholas V, artistic forerunner of Julius II and Leo X, had had it pulled down, together with the temple of Probus Anicius which adjoined it. In their place he had had the foundations of a new temple laid by the architects Rossellini and Battista Alberti; but some years later, after the death of Nicholas V, Paul II, the Venetian, had not been able to give more than five thousand crowns to continue the project of his predecessor, and thus the building was arrested when it had scarcely risen above the ground, and presented the appearance of a still-born edifice, even sadder than that of a ruin. As to the piazza itself, it had not yet, as the reader will understand from the foregoing explanation, either the fine colonnade of Bernini, or the dancing fountains, or that Egyptian obelisk which, according to Pliny, was set up by the Pharaoh at Heliopolis, and transferred to Rome by Caligula, who set it up in Nero’s Circus, where it remained till 1586. Now, as Nero’s Circus was situate on the very ground where St. Peter’s now stands, and the base of this obelisk covered the actual site where the vestry now is, it looked like a gigantic needle shooting up from the middle of truncated columns, walls of unequal height, and half-carved stones. On the right of this building, a ruin from its cradle, arose the Vatican, a splendid Tower of Babel, to which all the celebrated architects of the Roman school contributed their work for a thousand years: at this epoch the two magnificent chapels did not exist, nor the twelve great halls, the two-and-twenty courts, the thirty staircases, and the two thousand bedchambers; for Pope Sixtus V, the sublime swineherd, who did so many things in a five years’ reign, had not yet been able to add the immense building which on the eastern side towers above the court of St. Damasius; still, it was truly the old sacred edifice, with its venerable associations, in which Charlemagne received hospitality when he was crowned emperor by Pope Leo III.
