I walked in the morning up the hill toward the Capuchins, where was then Cardinal Unufrio (brother to the late Pope Urban VIII.) of the same order. He built them a pretty church, full of rare pictures, and there lies the body of St. Felix, that they say still does miracles. The piece at the great altar is by Lanfranc. It is a lofty edifice, with a beautiful avenue of trees, and in a good air. After dinner, passing along the Strada del Corso, I observed the column of Antoninus, passing under Arco Portugallo, which is but a relic, heretofore erected in honor of Domitian, called now Portugallo, from a Cardinal living near it. A little further on the right hand stands the column in a small piazza, here[Pg 167]tofore set up in honor of M. Aurelius Antoninus, comprehending in a basso-relievo of white marble his hostile acts against the Parthians, Armenians, Germans, etc; but it is now somewhat decayed. On the summit has been placed the image of St. Paul, of gilded copper. The pillar is said to be 161 feet high, ascended by 207 steps, receiving light by fifty-six apertures, without defacing the sculpture.

At a little distance, are the relics of the Emperor's palace, the heads of whose pillars show them to have been Corinthian.

Turning a little down, we came to another piazza, in which stands a sumptuous vase of porphyry, and a fair fountain; but the grace of this market, and indeed the admiration of the whole world, is the Pantheon, now called S. Maria della Rotonda, formerly sacred to all the Gods, and still remaining the most entire antiquity of the city. It was built by Marcus Agrippa, as testifies the architrave of the portico, sustained by thirteen pillars of Theban marble, six feet thick, and fifty-three in height, of one entire stone. In this porch is an old inscription.

Entering the church, we admire the fabric, wholly covered with one cupola, seemingly suspended in the air, and receiving light by a hole in the middle only. The structure is near as high as broad, viz, 144 feet, not counting the thickness of the walls, which is twenty-two more to the top, all of white marble; and, till Urban VIII. converted part of the metal into ordnance of war against the Duke of Parma, and part to make the high altar in St. Peter's, it was all over covered with Corinthian brass, ascending by forty degrees within the roof, or convex, of the cupola, richly carved in octagons in the stone. There are niches in the walls, in which stood heretofore the statues of Jupiter and the other Gods and Goddesses; for here was that Venus which had hung in her ear the other Union28 that Cleopatra was about to dis[Pg 168]solve and drink up, as she had done its fellow. There are several of these niches, one above another for the celestial, terrestrial, and subterranean deities; but the place is now converted into a church dedicated to the Blessed Virgin and all the Saints. The pavement is excellent, and the vast folding-gates, of Corinthian brass. In a word, it is of all the Roman antiquities the most worthy of notice. There lie interred in this Temple the famous Raphael di Urbino, Perino del Vaga, F. Zuccharo, and other painters.

Returning home, we pass by Cardinal Cajetan's Palace, a noble piece of architecture of Vincenzo Ammanatti, which is the grace of the whole Corso.
