After leaving the infernal regions, and entering purgatory, they find an immense cone divided into seven circles, each of which is devoted to the expiation of one of the seven mortal sins. The proud are overwhelmed with enormous weights; the envious are clothed in garments of horse-hair, their eye-lids closed; the choleric are suffocated with smoke; the indolent are compelled to run about continually; the avaricious are prostrated upon the earth; epicures are afflicted with hunger and thirst; and the incontinent expiate their crimes in fire. In this portion of the work, however, while there is much to admire, there is less to excite and sustain the interest. On the summit of the purgatorial mountain is the terrestrial paradise, whence is the only assent to the celestial. Beatrice, the object of his early and constant affection, descends hither to meet the poet. Virgil disappears, and she becomes his only guide. She conducts him through the nine heavens, and makes him acquainted with the great men who, by their virtuous lives, have deserved the highest enjoyments of eternity. In the ninth celestial sphere, Dante is favored with a manifestation of divinity, veiled, however, by three hierarchies of attending angels. He sees the Virgin Mary, and the saints of the Old and New Testament, and by these personages, and by Beatrice, all his doubts and difficulties are finally solved, and the conclusion leaves him absorbed in the beatific vision. The allegorical meaning of the poem is hidden under the literal one. Dante, traveling through the invisible world, is a symbol of mankind aiming at the double object of temporal and eternal happiness. The forest typifies the civil and religious confusion of society deprived of its two judges, the pope and the emperor. The three beasts are the powers which offered the greatest obstacles to Dante's designs, Florence, France, and the papal court. Virgil represents reason and the empire, and Beatrice symbolizes the supernatural aid, without which man cannot attain the supreme end, which is God. But the merit of the poem is that for the first time classic art is transferred into a Romance form. Dante is, above all, a great artist. Whether he describes nature, analyzes passions, curses the vices, or sings hymns to the virtues, he is always wonderful for the grandeur and delicacy of his art. He took his materials from mythology, history, and philosophy, but more especially from his own passions of hatred and love, breathed into them the breath of genius and produced the greatest work of modern times.
