Some of the principal streets are of considerable length, and perfectly straight. That called the Corso, is the most frequented. It runs from the Porto del Popolo, along the side of the Campus Martius, next to the ancient city. Here the nobility display their equipages during the carnival, and take the air in the evenings in fine weather. It is indeed the great scene of Roman magnificence and amusement. The shops on each side, are three or four feet higher than the street; and there is a path for the conveniency of foot passengers, on a level with the shops. The palaces, of which there are several in this street, range in a line with the houses, having no court before them, as the hotels in Paris have; and not being shut up from the sight of the citizens by high gloomy walls, as Devonshire and Burlington houses in London are. Such dismal barricades are more suitable to the unsocial character of a proud Baron, in the days of aristocratic tyranny, than to the hospitable benevolent disposition of their present proprietor. The Corso, I have said, commences at the fine area immediately within the Porto del Popolo. This is the gate by which we entered Rome; it is built in a noble style of elegant simplicity, from the design of Michael Angelo, executed by Bernini. The Strada Felice, in the higher part of the city, is about a mile and a half in length from the Trinità del Monte, to the church of St. John Lateran, on the Pincean hill. This street runs in a straight line, but the view is interrupted by a fine church called St. Maria Maggiore. The Strada Felice is crossed by another straight street, called the Strada di Porta Pia, terminated at one end by that gate; and at the other by four colossal statues in white marble, of two horses led by two men; supposed by some, to be representations of Alexander taming Bucephalus; and according to others, of Castor and Pollux. They are placed before the Pope’s palace, on the Quirinal Hill, and have a noble effect.
