SECOND ROOM.--Illustrative of Theology, _on the entry wall_; Poetry, _over the window_; Philosophy, _in front_; and Jurisprudence, _on the right_. Representations of the Fall of Man, the Flaying of Marsyas, the Study of the Globe, the Judgment of Solomon, _on the ceiling_. _On the walls_ corresponding--the Dispute on the Sacrament, Mount Parnassus, the School of Athens (a portico crowded with philosophers, which gives its name to the room), Prudence, Fortitude, and Temperance. THIRD ROOM.--_In front_, the Miraculous Expulsion of Heliodorus from the Temple; _on the right_, the Mass of Bolsena; _on the entry wall_, Attila driven back from Rome by Leo I.; _over the left window_, S. Peter's Release from Prison (notice the four different lights here). _The ceiling_ represents subjects from the Old Testament. FOURTH ROOM.--_On the right_, Battle between Constantine and Maxentius at the Ponte Molle; _entry wall_, Baptism of Constantine; _left wall_, Rome presented by Constantine to Silvester; _in front_, the Cross appearing to Constantine (the dwarf is Gradasso da Norcia, from Berni's Poetry); _on the vault_, the pagan statue thrown down represents the Triumph of Faith, by Lauretti (notice the wonderful bit of perspective here); _on the right-hand corner, a door leads into the_ ANTICAMERA OF THE STANZE, originally painted by Raphael, restored by Carlo Maratta. _Out of this room is_ THE CHAPEL OF S. LORENZO. The frescoes are by Fra Angelico, representing events in the lives of SS. Stephen and Laurence. _On the ceiling_ are the four Evangelists. It was built as the private chapel of Nicholas V., and is the oldest decorated portion of the Vatican. _We now pass into_ THE LOGGIE OF RAPHAEL, _to the right on entering_. "It is impossible either to execute or imagine a more beautiful work" (Vasari). It is called Raphael's Bible. It is divided into thirteen arcades, each containing four subjects of Scripture history--1. The Creation of the World, by Raphael; 2. History of Adam and Eve; 3. The History of Noah, by Giulio Romano; 4. Abraham and Lot; 5. History of Isaac, by Penni; 6. Jacob, by Pellegrino; 7. Joseph; 8. Moses, by Giulio Romano; 9. Moses, by Raffaello del Colle; 10. Joshua; 11. David, by Pierino del Vaga; 12. Solomon, by Pellegrino; 13. From the New Testament, by Giulio Romano. The stucco ornaments and arabesque work are by Giovanni da Udine, from Raphael's designs, who took the idea from the Golden House of Nero. The weather has very much damaged them. Pius IX. put the glass windows in. _The other sides_ were built by Gregory XIII., and executed by Giovanni da Udine; they have recently been restored by Mantovani. _The farther one_, parallel with the Papal apartments, is where his holiness gives audience. _A flight of stairs on the left leads to the_ Upper Loggia, painted with maps and landscapes. _Entrance to the Picture Gallery--ring the bell at the second door on the left of the Central Loggia._ THE PICTURE GALLERY.
