Entering the church by the west door, and following the right aisle, the first chapel (Venuti, formerly Della Rovere[3]) is adorned with exquisite paintings by _Pinturicchio_. Over the altar is the Nativity--one of the most beautiful frescoes in the city; in the lunettes are scenes from the life of St. Jerome. Cardinal Christoforo della Rovere, who built this chapel and dedicated it to "the Virgin and St. Jerome," is buried on the left, in a grand fifteenth century tomb; on the right is the monument of Cardinal di Castro. Both of these tombs and many others in this church have interesting and greatly varied lunettes of the Virgin and Child. The second chapel, of the Cibo family, rich in pillars of nero-antico and jasper, has an altarpiece representing the Assumption of the Virgin, by _Carlo Maratta_. In the cupola is the Almighty, surrounded by the heavenly host.[4] The third chapel is also painted by _Pinturicchio_. Over the altar, the Madonna and four saints; above, God the Father, surrounded by angels. In the other lunettes, scenes in the life of the Virgin;--that of the Virgin studying in the Temple, a very rare subject, is especially beautiful. In a frieze round the lower part of the wall, a series of martyrdoms in grisaille. On the right is the tomb of Giovanni della Rovere, ob. 1483. On the left is a fine sleeping bronze figure of a bishop, unknown. The fourth chapel has a fine fifteenth century altar-relief of St. Catherine between St. Anthony of Padua and St. Vincent. On the right is the tomb of Marc-Antonio Albertoni, ob. 1485; on the left, that of Cardinal Costa, of Lisbon, ob. 1508, erected in his lifetime. In this tomb is an especially beautiful lunette of the Virgin adored by Angels. Entering the right transept, on the right is the tomb of Cardinal Podocanthorus of Cyprus, a very fine specimen of fifteenth century work. A door near this leads into a cloister, where is preserved, over a door, the Gothic altar-piece of the church of Sixtus IV, representing the Coronation of the Virgin, and two fine tombs--Archbishop Rocca, ob. 1482, and Bishop Gomiel. The choir (shown when there is no service) has a ceiling by _Pinturicchio_. In the centre, the Virgin and Saviour, surrounded by the Evangelists and Sibyls; in the corners, the Fathers of the Church--Gregory, Ambrose, Jerome, and Augustine. Beneath are the tombs of Cardinal Ascanio Sforza, and Cardinal Girolamo Basso, nephews of Sixtus IV. (Francesco della Rovere), beautiful works of _Andrea di Sansovino_. These tombs were erected at the expense of Julius II., himself a Della Rovere, who also gave the windows, painted by _Claude and Guillaume de Marseilles_, the only good specimens of stained glass in Rome.
