In the first chapel, to the right, the picture over the altar, the Nativity of Jesus Christ, and the frescoes of the lunettes are by Pinturicchio. The second chapel is that of the Cibo family--rich in marbles, and adorned with forty-six columns of Sicilian jasper. The picture of the Conception is by Maratta. The third chapel is painted by Pinturicchio. In the fourth chapel is an interesting bas-relief of the fifteenth century. The painting of the Virgin, on the high altar, is one of those attributed to S. Luke; the paintings of the vault in the choir are by Pinturicchio. The two monuments in marble ornamented by statues are by Contucci da S. Savino. The last chapel but one, in the small nave, is that of the Chigi family, and is one of the most celebrated in Rome. Raphael gave the design for the dome, for the paintings of the frieze, and for the picture of the altar, which was commenced by Sebastiano del Piombo, and terminated by Francesco Salviati. The statues of Daniel and Habakkuk were executed by Bernini. The front of the altar and the statues of Elias and Jonah are by Lorenzetti; but the design of the last is by Raphael. THE CORSO (Il Corso). Starting on our first ramble, we will take the line of the principal street, the Corso, which takes its name from the races held during the Carnival. It is on the line of the old Via Flaminia, the great highroad which ran through the Campus Martius to the north. Many handsome churches and palaces face the street, which is rather narrow compared with our modern requirements. The Corso is the principal promenade of the Romans, and possesses many points of interest. At No. 18, _on the left_, lived Goethe; just beyond, _on the right_, in the short Via S. Giacomo, was Canova's studio. _On the right_, further down, is the Church of S. Carlo; passing by which, crossing the line of the Via Condotti, _on our right_ opens out the small square of S. Lorenzo, in which is the CHURCH OF S. LORENZO IN LUCINA, containing the grand work of Guido Reni, "The Crucifixion." It is said that, being absorbed in his subject, he crucified his model. The church contains a monument to Poussin, the relief being a copy of his landscape of the tomb of Sappho in Arcadia. Opposite this church is the English Baptist Chapel, under the Rev. James Wall, founded for Romans. _Turning to the right, down the Corso, on the left, the Via Convertite leads to_ THE GENERAL POST OFFICE (La Posta), in the Piazza S. Silvestro, _on the left_. It is a new building, recently opened, and is fitted up with every modern appliance. The garden in the centre, and the surrounding arcade with its frescoes, present a refreshing appearance, and give a good idea of what the court of a palace should be. _Opposite_, in the right corner of the square, is THE ENGLISH CHURCH OF THE HOLY TRINITY, being the first Protestant church erected in Rome. It is in the form of a basilica without aisles, and was designed by the late architect Cipolla.
