SECTION LXVIII. After thus hearing praise rendered to God by the angels for the salvation of the newly-entered soul, it was thought fittest that the worshipper should be led to contemplate, in the most comprehensive forms possible, the past evidence and the future hopes of Christianity, as summed up in three facts without assurance of which all faith is vain; namely that Christ died, that He rose again, and that He ascended into heaven, there to prepare a place for His elect. On the vault between the first and second cupolas are represented the crucifixion and resurrection of Christ, with the usual series of intermediate scenes,--the treason of Judas, the judgment of Pilate, the crowning with thorns, the descent into Hades, the visit of the women to the sepulchre, and the apparition to Mary Magdalene. The second cupola itself, which is the central and principal one of the church, is entirely occupied by the subject of the Ascension. At the highest point of it Christ is represented as rising into the blue heaven, borne up by four angels, and throned upon a rainbow, the type of reconciliation. Beneath him, the twelve apostles are seen upon the Mount of Olives, with the Madonna, and, in the midst of them, the two men in white apparel who appeared at the moment of the Ascension, above whom, as uttered by them, are inscribed the words, "Ye men of Galilee, why stand ye gazing up into heaven? This Christ, the Son of God, as He is taken from you, shall so come, the arbiter of the earth, trusted to do judgment and justice." SECTION LXIX. Beneath the circle of the apostles, between the windows of the cupola, are represented the Christian virtues, as sequent upon the crucifixion of the flesh, and the spiritual ascension together with Christ. Beneath them, on the vaults which support the angles of the cupola, are placed the four Evangelists, because on their evidence our assurance of the fact of the ascension rests; and, finally, beneath their feet, as symbols of the sweetness and fulness of the Gospel which they declared, are represented the four rivers of Paradise, Pison, Gihon, Tigris, and Euphrates.
