The same idea had occurred to Pierre, and was filling him with emotion. People talked of the Vatican being closed, and pictured a dark, gloomy palace, encompassed by high walls, whereas this palace overlooked all Rome, and the Pope from his window could see the world. Pierre himself had viewed the panorama from the summit of the Janiculum, the /loggie/ of Raffaelle, and the dome of St. Peter's, and so he well knew what it was that Leo XIII was able to behold. In the centre of the vast desert of the Campagna, bounded by the Sabine and Alban mountains, the seven illustrious hills appeared to him with their trees and edifices. His eyes ranged also over all the basilicas, Santa Maria Maggiore, San Giovanni in Laterano, the cradle of the papacy, San Paolo-fuori-le-Mura, Santa Croce in Gerusalemme, Sant' Agnese, and the others; they beheld, too, the domes of the Gesu of Sant' Andrea della Valle, San Carlo and San Giovanni dei Fiorentini, and indeed all those four hundred churches of Rome which make the city like a /campo santo/ studded with crosses. And Leo XIII could moreover see the famous monuments testifying to the pride of successive centuries--the Castle of Sant' Angelo, that imperial mausoleum which was transformed into a papal fortress, the distant white line of the tombs of the Appian Way, the scattered ruins of the baths of Caracalla and the abode of Septimius Severus; and then, after the innumerable columns, porticoes, and triumphal arches, there were the palaces and villas of the sumptuous cardinals of the Renascence, the Palazzo Farnese, the Palazzo Borghese, the Villa Medici, and others, amidst a swarming of facades and roofs. But, in particular, just under his window, on the left, the Pope was able to see the abominations of the unfinished district of the castle fields. In the afternoon, when he strolled through his gardens, bastioned by the wall of the fourth Leo like the plateau of a citadel, his view stretched over the ravaged valley at the foot of Monte Mario, where so many brick-works were established during the building frenzy. The green slopes are still ripped up, yellow trenches intersect them in all directions, and the closed works and factories have become wretched ruins with lofty, black, and smokeless chimneys. And at any other hour of the day Leo XIII could not approach his window without beholding the abandoned houses for which all those brick-fields had worked, those houses which had died before they even lived, and where there was now nought but the swarming misery of Rome, rotting there like some decomposition of olden society.
