All her companions also wished to be brides of Christ, but patiently did their duty, and, knowing that "in His will is our tranquillity," they now spend all their time singing "Ave Maria." When these nun-like forms vanish, Dante gazes at Beatrice in hopes of learning more.
Canto IV. In reply to Dante's inquiring glance, Beatrice explains that those compelled to sin against their desire are ever held blameless in Heaven. Then, stating:
"Not seldom, brother, it hath, chanced for men
To do what they had gladly left undone;"
she adds that "the will that wills not, still survives unquenched," and that by will power only St. Lawrence and Mucius Scevola were enabled to brave fire. Then she makes him see how truth alone can satisfy a mind athirst for knowledge.
Canto V. Beatrice asserts that the most precious gift bestowed upon mankind was freedom of will, and that "knowledge comes of learning well retain'd." She concludes that when man makes a vow he offers his will in sacrifice to God, and that for that reason no vow should be thoughtlessly made, but all should be rigidly kept. Still, she admits it is better to break a promise than, like Jephthah and Agamemnon, to subscribe to a heinous crime, and states that either Testament can serve as guide for Jews or Christians. Again drawing Dante upward by the very intensity of her gaze, she conveys him to the second circle, the heaven of Mercury (revolved by Archangels). Here, in an atmosphere as pellucid as water, Dante perceives thousands of angels, coming toward him, singing "Lo! one arrived to multiply our loves!" These spirits assure Dante he was born in a happy hour, since he is allowed, ere the "close of fleshly warfare," to view the glories of heaven,—and express a desire to share their lights with him. So Dante questions the spirit nearest him, which immediately glows with loving eagerness to serve him, until it becomes a dazzling point of light.
Canto VI. This spirit announces he is Justinian, chosen to clear "from vain excess the encumbered laws," five hundred years after the Christian era began, and that it was in order to devote all his time to this task that he consigned the military power to Belisarius. He proceeds to give Dante a résumé of Roman history, from the kidnapping of the Sabines to his own day, laying stress on the triumphs won by great generals. He also specially mentions the hour "When Heaven was minded that o'er all the world his own deep calm should brood," the troublous days of the empire, and the feud of the Guelfs and Ghibellines, the two principal political factions of Dante's time. Next he explains that Mercury is inhabited by "good spirits whose mortal lives were busied to that end that honor and renown might wait on them," and quotes in particular Raymond Bérenger, whose four daughters became queens.
Canto VII. After this speech Justinian vanishes with his angelic companions, and Dante, duly encouraged, inquires of Beatrice how "just revenge could be with justice punished!" She informs him that, as in Adam all die through the power of sin, all can by faith live again through Christ, thanks to God's goodness.
Canto VIII. Although unaware of the fact, Dante, whose eyes have been fixed on Beatrice, has during her exposition been wafted up to the third heaven, that of Venus (revolved by Princedoms). In the planet of love—where Beatrice glows with increased beauty—are innumerable souls "imperfect through excess of love," which are grouped in constantly revolving circles. All at once one of these luminous spirits approaches Dante, and, after expressing great readiness to serve him, introduces himself as Charles Martel, King of Hungary, brother of Robert of Naples. Thirsting for information, Dante inquires of him "how bitter can spring when sweet is sown?" In a lengthy disquisition in reply, this spirit mentions how children often differ from their parents, quotes Esau and Jacob as marked examples thereof, and adds that nature, guided by Providence, produces at will a Solon, Xerxes, Melchisedec, or Daedalus. Canto IX. The next spirit with whom Beatrice converses is the fair Cunizza, who like the Magdalen "loved much," and therefor obtained pardon for her sins. Before vanishing, she foretells coming political events, and introduces the Provençal bard Folco, whose poems on love were to be republished after five hundred years of oblivion. After relating his life, this poet informs Dante the harlot Rahab was admitted to this heaven in reward for saving Joshua's spies. This spirit concludes his interview by censuring the present papal policy, declaring it far too worldly, avaricious, and time-serving to find favor in heaven.
Canto X. Drawn upward this time by the attraction of the sun, Dante finds himself in a dazzling sphere (revolved by Powers), where he and Beatrice behold consecutive moving wreaths, each composed of twelve blessed spirits who while on earth were noted as teachers of divinity and philosophy. One of these singing, revolving wreaths encompasses our travellers, until one of its members, St. Thomas Aquinas, ceases his ineffable song long enough to present his companions and explain their titles to immortal glory.
Canto XI. St. Thomas Aquinas, in his conversation with Dante, relates the life of St. Francis of Assisi, dwelling particularly upon his noble character, and describing how, after becoming wedded to Poverty, he founded the order of the Franciscans, received the stigmata, and died in odor of sanctity, leaving worthy disciples and emulators, such as St. Dominic, to continue and further the good work he had begun. He adds that many of the saint's followers are represented in the innumerable glowing wreaths which people the heaven of the Sun.
