The pictures in the church were brought from S. Peter's, and the court of the monastery, formed with one hundred columns, was designed by Michael Angelo. Salvator Rosa and Carlo Maratta were both buried here. The Government is forming a new museum in these buildings. On the right of the high altar is Domenichino's S. Sebastian. _Opposite to it_, Maratta's Baptism of our Lord. The Presentation in the Temple is by Romanelli; the Death of Ananias by Roncalli. In the transept are copies of Guido's Crucifixion of S. Peter, and Vanni's Fall of Simon Magus; S. Peter resuscitating Tabitha, by Mancini; S. Jerome and S. Francis, by Musciano; Assumption, by Bianchini; Resuscitation of Tabitha, by Costanzi; Fall of Simon Magus, by Battoni; S. Basil celebrating Mass before the Emperor Valens, by Subleyras. _On leaving the church, opposite_ are the remains of the THEATRIDIUM belonging to the baths, the space in front being the Stadium. THE VIA NAZIONALE commences here, and runs down to the south end of the Corso. The street is traversed by a line of tram-cars, which run down to the Piazza di Venezia. It is the handsomest street in Rome, and is lined by several fine blocks of buildings. It is on the line of the ancient Vicus Longus. Upon the _right_ is the Quirinal Hill; and on the _left_, the Viminal; the street, artificially raised, occupying the valley between the two hills. A short distance down on the left is the Quirinal Hotel, the largest in Rome, fitted up with every modern comfort, and on one of the healthiest sites in the city. Behind is Costanzi's new theatre. _Just below is the_ CHURCH OF S. PAUL'S WITHIN THE WALLS, the new American Episcopal Church under Dr. Nevin; designed by Mr. George Street in the Gothic style. It has a fine campanile, and a beautiful peal of bells. The vault of the tribunal in mosaic was designed by Mr. Burne Jones, and represents Christ surrounded by the celestial company, as described in Holy Writ. THE EXHIBITION OF FINE ARTS. The new Palace of Fine Arts is on the right, about half-way down. In it is held an annual exhibition of modern works of art of every description. Admission, one lira; Sundays, fifty centesimi. It occupies a space of 22,030 square mètres--the permanent building being 5,280 square mètres; the Crystal Hall, 1,250 square mètres; the gardens, 5,000 square mètres; and the temporary galleries, 10,500 square mètres. The palace comprises two floors, and may be entered from the Via Nazionale, Via Genova, and Via del Quirinale. The main front is 25 mètres high and 60 long. Sixteen statues decorate the top of the façade, the work of Roman artists. On the top of the pediment is a group, Italy crowning Art, by Adalberto Cencetti, the groups in relief on the face being the Finding of the Laocoon Group, by Filippo Ferrari, and Carrying Cimabue's Madonna in Triumph, by Puntoni.
