A narrow gallery there ran round the dome just above the frieze, on which, in letters five feet high, appeared the famous inscription: /Tu es Petrus et super hanc petram oedificabo ecclesiam meam et tibi dabo claves regni coelorum.* And then, as Pierre leant over to gaze into the fearful cavity beneath him and the wide openings of nave, and aisles, and transepts, the cry, the delirious cry of the multitude, yet clamorously swarming below, struck him full in the face. He fled once more; but, higher up, yet a second time he pushed another door open and found another gallery, one perched above the windows, just where the splendid mosaics begin, and whence the crowd seemed to him lost in the depths of a dizzy abyss, altar and /baldacchino/ alike looking no larger than toys. And yet the cry of idolatry and warfare arose again, and smote him like the buffet of a tempest which gathers increase of strength the farther it rushes. So to escape it he had to climb higher still, even to the outer gallery which encircles the lantern, hovering in the very heavens. * Thou art Peter (Petrus) and on that rock (Petram) will I build my church, and to thee will I give the keys of the Kingdom of Heaven. How delightful was the relief which that bath of air and sunlight at first brought him! Above him now there only remained the ball of gilt copper into which emperors and queens have ascended, as is testified by the pompous inscriptions in the passages; a hollow ball it is, where the voice crashes like thunder, where all the sounds of space reverberate. As he emerged on the side of the apse, his eyes at first plunged into the papal gardens, whose clumps of trees seemed mere bushes almost level with the soil; and he could retrace his recent stroll among them, the broad /parterre/ looking like a faded Smyrna rug, the large wood showing the deep glaucous greenery of a stagnant pool. Then there were the kitchen garden and the vineyard easily identified and tended with care. The fountains, the observatory, the casino, where the Pope spent the hot days of summer, showed merely like little white spots in those undulating grounds, walled in like any other estate, but with the fearsome rampart of the fourth Leo, which yet retained its fortress-like aspect. However, Pierre took his way round the narrow gallery and abruptly found himself in front of Rome, a sudden and immense expanse, with the distant sea on the west, the uninterrupted mountain chains on the east and the south, the Roman Campagna stretching to the horizon like a bare and greenish desert, while the city, the Eternal City, was spread out at his feet. Never before had space impressed him so majestically. Rome was there, as a bird might see it, within the glance, as distinct as some geographical plan executed in relief. To think of it, such a past, such a history, so much grandeur, and Rome so dwarfed and contracted by distance! Houses as
