St. Peter raising Petronilla from her sick bed is one of the subjects by Masaccio in the Brancacci Chapel. The scene of her entombment is the subject of a once celebrated and colossal picture by Guercino: the copy in mosaic is over the altar dedicated to her in St. Peter’s: in front, and in the lower part of the picture, she is just seen as they are letting her down into the grave, crowned with roses; behind stands Flaccus with a handkerchief in his hand, and a crowd of spectators: in the upper part of the picture Petronilla is already in Paradise, kneeling, in a rich dress, before the feet of Christ, having exchanged an earthly for a heavenly bridegroom. This great picture exhibits, in a surpassing degree, the merits and defects of Guercino; it is effective, dramatic, deeply and forcibly coloured, and arrests attention: on the other hand, it is coarse, crowded, vulgar in sentiment, and repugnant to our better taste. There is a standing figure of Petronilla in the Duomo at Lucca, by Daniel di Volterra, very fine.[195] * * * * * The life of St. Peter, when represented as a series, generally comprises the following subjects, commencing with the first important incident after the Ascension of Christ. 1. Peter and John heal the lame man at the Beautiful Gate. 2. Peter heals the paralytic Eneas. 3. Peter raises Tabitha. 4. The angel takes off the chains of Peter. 5. He follows the angel out of the prison. 6. St. Peter and St. Paul meet at Rome. 7. Peter and Paul before Nero are accused by Simon Magus. 8. The fall of Simon Magus. 9. The crucifixion of St. Peter. This example is taken from the series of mosaics in the Cathedral of Monreale, at Palermo. The fine series of frescoes in the Brancacci Chapel at Florence is differently arranged; thus:—1. The tribute money found in the fish by St. Peter. 2. Peter preaching to the converts. 3. Peter baptizes the converts. In this fresco, the youth, who has thrown off his garments and is preparing for baptism, is famous as the first really graceful and well-drawn undraped figure which had been produced since the revival of Art. 4. Peter and John heal the cripple at the Beautiful Gate, and Petronilla is raised from her bed. 5. Peter in his prison is visited by Paul. 6. Peter delivered by the angel. 7. The resuscitation of the dead youth. 8. The sick are laid in the way of Peter and John, ‘that at the least the shadow of Peter passing by might overshadow some of them.’ 9. Peter and John distribute alms; a dead figure lies at the feet of the apostles, perhaps Ananias. The situation of the fresco is very dark, so that it is difficult to distinguish the action and expression of the figures. 10. Peter and Paul accused before Nero. 11. The crucifixion of Peter.
