TRASTEVERE—WALLS. _Rome, May, 1817._ I CONCLUDED my last with a promise, or perhaps I should say a threat, of a walk in the Trastevere, which I am now about to perform. I shall not however, entirely skip over the intervening ground, but glean whatever occurs on the way; and first I will take you to San Carlo, in the Corso; a church which looks better at a distance than near, because the general form of the front is that of a Greek temple crowned with a pediment, but on approaching we find so many breaks and angles, cutting through cornice, pediment, and everything else, that all beauty of design is lost: the interior is good, but there are others better of the same sort in Rome. Another church in the Corso, is that of Gesù e Maria. Not by any means one of the largest, or richest churches in this city, yet a priest who accompanied me, assured me that he had spent 7,000 crowns, raised entirely by voluntary contributions, in putting up an altar, and otherwise decorating one of the side chapels; and there is no reason to distrust his information. It was dedicated to La Madonna del divin Ajuto, and the father gave me her picture. Not far from this is the Palazzo Rondadini, famous not in itself, but for two exquisite festoons of fruit and leaves in white marble, built up in the wall of the court. At a very short distance is the Mausoleum of Augustus, originally a vast circular edifice, composed of concentric circles, rising higher as they approached the middle, and forming a succession of terraces adorned with trees,[2] as we learn from the medals representing it. The outer circle, or perhaps circles, are now destroyed; and we have only the central mass formed of rubble, with facings of reticulated work, and the upper part reduced into an amphitheatre for the exhibition of fire-works, and of bull-fights. What is below I do not know. Piroli has given a section which represents it as nearly solid.
