The Divine Comedy

The Divine Comedy is composed of three canticas (or "cantiche") — Inferno (Hell), Purgatorio (Purgatory), and Paradiso (Paradise) — composed each of 33 cantos (or "canti"). The very first canto serves as an introduction to the poem and is generally not considered to be part of the first cantica, bringing the total number of cantos to 100. The number 3 is prominent in the work, represented here by the length of each cantica. The verse scheme used, terza rima, is the hendecasyllable (line of eleven syllables), with the lines composing tercets according to the rhyme scheme ABA BCB CDC . . . YZY Z.

The poet tells in the first person his travel through the three realms of the dead, lasting during the Easter Triduum in the spring of 1300. The Roman poet Virgil guides him through Hell and Purgatory; Beatrice, Dante's ideal woman, guides him through Heaven. Beatrice was a real Florentine woman whom he met in childhood and admired from afar in the mode of the then-fashionable courtly love tradition which is highlighted in Dante's earlier work La Vita Nuova.

In Northern Italy's political struggle between Guelphs and Ghibellines, Dante was part of the Guelphs, who in general favored the Papacy over the Holy Roman Emperor. Florence's Guelphs split into factions around 1300: the White Guelphs, who opposed secular rule by Pope Boniface VIII and who wished to preserve Florence's independence, and the Black Guelphs, who favored the Pope's control of Florence. Dante was among the White Guelphs who were exiled in 1302 by the Lord-Mayor Cante de' Gabrielli di Gubbio, after troops under Charles of Valois entered the city, at the request of Boniface and in alliance with the Blacks. The Pope said if he had returned he would be burned at the stake. This exile, which lasted the rest of Dante's life, shows its influence in many parts of the Comedy, from prophecies of Dante's exile to Dante's views of politics to the eternal damnation of some of his opponents.

In Hell and Purgatory, Dante shares in the sin and the penitence respectively. The last word in each of the three parts of The Divine Comedy is "stars."

Inferno
The poem begins on Good Friday of the year 1300, "In the middle of our life's journey" (Nel mezzo del cammin di nostra vita), and so opens in medias res. Dante is thirty-five years old, half of the biblically allotted age of 70 (Psalm 90:10), lost in a dark wood (perhaps, allegorically, contemplating suicide—as "wood" is figured in Canto XIII, and also the mention of suicide is made in Canto I of Purgatorio with "This man has not yet seen his last evening; But, through his madness, was so close to it, That there was hardly time to turn about" implying that when Virgil came to him he was on the verge of suicide or morally passing the point of no return), assailed by beasts (a lion, a leopard, and a she-wolf; allegorical depictions of temptations towards sin) he cannot evade, and unable to find the "straight way" (diritta via) to salvation (symbolized by the sun behind the mountain). Conscious that he is ruining himself, that he is falling into a "deep place" (basso loco) where the sun is silent ('l sol tace), Dante is at last rescued by Virgil after his love Beatrice intercedes on his behalf (Canto II), and he and Virgil begin their journey to the underworld.

Dante passes through the gate of hell, on which is inscribed the famous phrase "Lasciate ogne speranza, voi ch'intrate", or "Abandon all hope, ye who enter here"[1] Before entering Hell completely, Dante and his guide see the Opportunists, souls of people who in life did nothing, neither for good nor evil (among these Dante recognizes either Pope Celestine V, or Pontius Pilate; the text is ambiguous). Mixed with them are the outcasts, who took no side in the Rebellion of Angels. These souls are neither in Hell nor out of it, but reside on the shores of the Acheron, their punishment to eternally pursue a banner, and be pursued by wasps and hornets that continually sting them while maggots and other such insects drink their blood and tears. This symbolizes the sting of their conscience and the repugnance of sin.

"The Barque of Dante" by Eugène DelacroixThen Dante and Virgil reach the ferry that will take them across the river Acheron and to Hell proper. The ferry is piloted by Charon, who does not want to let Dante enter, for he is a living being. Virgil forces Charon to take them, but their passage across is undescribed since Dante faints and does not awake until he is on the other side.

The Circles of Hell
Virgil guides Dante through the nine circles of Hell. The circles are concentric, each new one representing further and further evil, culminating in the center of the earth, where Satan is held, bound. Each circle's sin is punished in a fashion fitting their crime: the sinner is afflicted by the chief sin he committed for all of eternity. Sinners such as these are found in Purgatory, but those in hell justify their sin and are unrepentant. Furthermore, those in hell have knowledge of the past and future, but not of the present. This is a joke on them in Dante's mind because after the Final Judgment, time ends; those in hell would then know nothing. The nine circles are:

Here reside the unbaptized and the virtuous pagans, who, though not sinful, did not accept Christ. Here also reside those who, if they lived before the coming of Christ, did not pay fitting homage to their respective deity. They are not punished in an active sense, but rather grieve only their separation from God, without hope of reconciliation. The chief irony in this circle is that Limbo shares many characteristics with Elysian Fields, thus the guiltless damned are punished by living in their deficient form of heaven. Their fault was that they lacked faith — the hope for something greater than rational minds can conceive. Limbo includes green fields and a castle, the dwelling place of the wisest men of antiquity, including Virgil himself. In the castle Dante meets the poets Homer, Horace, Ovid, and Lucan. Interestingly, he also sees Saladin in Limbo. (Canto IV) Dante implies that all virtuous pagans find themselves here, although he later encounters two in heaven and one in purgatory.
Beyond the first circle, all of those condemned for active, deliberately willed sin are judged by Minos, who sentences each soul to one of the lower eight circles. These are structured according to the classical (Aristotelian) conception of virtue and vice, so that they are grouped into the sins of incontinence, violence, and fraud (which for many commentators are represented by the leopard, lion, and she-wolf[2]). The sins of incontinence — weakness in controlling one's desires and natural urges — are the mildest among them, and, correspondingly, appear first:

Second Circle. Those overcome by lust are punished in this circle. They are the first ones to be truly punished in Hell. These souls are blown about to and fro by a violent storm, without hope of rest. This symbolizes the power of lust to blow one about needlessly and aimlessly. Francesca da Rimini informs Dante of how she and her husband's brother Paolo committed adultery and died a violent death at the hands of her husband. (Canto V)
Third Circle. Cerberus guards the gluttons, forced to lie in the mud under continual cold rain and hail. Dante converses with a Florentine contemporary identified as Ciacco ("Hog" — probably a nickname) regarding strife in Florence and the fate of prominent Florentines. (Canto VI)
Fourth Circle. Those whose concern for material goods deviated from the desired mean are punished in this circle. They include the avaricious or miserly, who hoarded possessions, and the prodigal, who squandered them. Guarded by Plutus, each group pushes a great weight against the heavy weight of the other group. After the weights crash together the process starts over again. (In Gustave Doré's illustrations for this scene, the damned push huge money bags.) (Canto VII)
Fifth Circle. In the swamp-like water of the river Styx, the wrathful fight each other on the surface, and the sullen or slothful lie gurgling beneath the water. Phlegyas reluctantly transports Dante and Virgil across the Styx in his skiff. On the way they are accosted by Filippo Argenti, a Black Guelph from a prominent family. (Cantos VII and VIII)
The lower parts of hell are contained within the walls of the city of Dis, which is itself surrounded by the Stygian marsh. Punished within Dis are active (rather than passive) sins. The walls of Dis are guarded by fallen angels. Virgil is unable to convince them to let Dante and him enter, and the Furies and Medusa threaten Dante. An angel sent from Heaven secures entry for the poets. (Cantos VIII and IX)

Sixth Circle. Heretics are trapped in flaming tombs. Dante holds discourse with a pair of Florentines in one of the tombs: Farinata degli Uberti, a Ghibelline; and Cavalcante de' Cavalcanti, a Guelph who was the father of Dante's friend, fellow poet Guido Cavalcanti. (Cantos X and XI)
Seventh Circle. This circle houses the violent. Its entry is guarded by the Minotaur, and it is divided into three rings:
Outer ring, housing the violent against people and property, who are immersed in Phlegethon, a river of boiling blood, to a level commensurate with their sins. The Centaurs, commanded by Chiron, patrol the ring. The centaur Nessus guides the poets along Phlegethon and across a ford in the river. (Canto XII)
Middle ring: In this ring are the suicides, who are transformed into gnarled thorny bushes and trees. They are torn at by the Harpies. Unique among the dead, the suicides will not be bodily resurrected after the final judgment. Instead they will maintain their bushy form, with their own corpses hanging from the limbs. Dante breaks a twig off of one of the bushes and hears the tale of Pier delle Vigne, who committed suicide after falling out of favor with Emperor Frederick II. The other residents of this ring are the profligates, who destroyed their lives by destroying the means by which life is sustained (i.e. money and property). They are perpetually chased by ferocious dogs through the thorny undergrowth. (Canto XIII) The trees are a metaphor; in life the only way of the relief of suffering was through pain (i.e. suicide) and in Hell, the only form of relief of the suffering is through pain (breaking of the limbs to bleed).
Inner ring: The violent against God (blasphemers), the violent against nature (sodomites), and the violent against art (usurers), all reside in a desert of flaming sand with fiery flakes raining from the sky. The blasphemers lie on the sand, the usurers sit, and the sodomites wander about in groups. Dante converses with two Florentine sodomites from different groups: Brunetto Latini, a poet; and Iacopo Rusticucci, a politician. (Cantos XIV through XVI) Those punished here for usury include Florentines Catello di Rosso Gianfigliazzi, Ciappo Ubriachi, and Giovanni di Buiamonte, and Paduans Reginaldo degli Scrovegni and Vitaliano di Iacopo Vitaliani.
The last two circles of Hell punish sins that involve conscious fraud or treachery. The circles can be reached only by descending a vast cliff, which Dante and Virgil do on the back of Geryon, a winged monster represented by Dante as having the face of an honest man and a body that ends in a scorpion-like stinger. (Canto XVII)

Dante's guide rebuffs Malacoda and his fiends between bolgia five and six in the Eighth Circle of Hell, Inferno, Canto 21.
Dante climbs the flinty steps in bolgia seven in the Eighth Circle of Hell, Inferno, Canto 26.Eighth Circle. The fraudulent—those guilty of deliberate, knowing evil—are located in a circle named Malebolge ("Evil Pockets"), divided into ten bolgie, or ditches of stone, with bridges spanning the ditches:
Bolgia 1: Panderers and seducers walk in separate lines in opposite directions, whipped by demons. In the group of panderers the poets notice Venedico Caccianemico, and in the group of seducers Virgil points out Jason.(Canto XVIII)
Bolgia 2: Flatterers are steeped in human excrement. (Canto XVIII)
Bolgia 3: Those who committed simony are placed head-first in holes in the rock, with flames burning on the soles of their feet. One of them, Pope Nicholas III, denounces as simonists two of his successors, Pope Boniface VIII and Pope Clement V. (Canto XIX)
Bolgia 4: Sorcerers and false prophets have their heads twisted around on their bodies backward, so they can only see what is behind them and not into the future.(Canto XX)
Bolgia 5: Corrupt politicians (barrators) are immersed in a lake of boiling pitch, guarded by devils, the Malebranche ("Evil Claws"). Their leader, Malacoda ("Evil Tail"), assigns a troop to escort Virgil and Dante to the next bridge. The troop hook and torment Ciampolo, who identifies some Italian grafters and then tricks the Malebranche in order to escape back into the pitch. (Cantos XXI through XXIII)
Bolgia 6: The bridge over this bolgia is broken: the poets climb down into it and find the Hypocrites listlessly walking along wearing gold-gilded lead cloaks. Dante speaks with Catalano and Loderingo, members of the Jovial Friars. It is also ironic in this canto that whilst in the company of hypocrites, the poets also discover that the guardians of the fraudulent (the malebranche) are hypocrites themselves, as they find that they have lied to them, giving false directions, when at the same time they are punishing liars for similar sins. (Canto XXIII)
Bolgia 7: Thieves, guarded by the centaur (as Dante describes him) Cacus, are pursued and bitten by snakes. The snake bites make them undergo various transformations, with some resurrected after being turned to ashes, some mutating into new creatures, and still others exchanging natures with the snakes, becoming snakes themselves that chase the other thieves in turn. (Cantos XXIV and XXV)
Bolgia 8: Fraudulent advisors are encased in individual flames. Dante includes Ulysses and Diomedes together here for their role in the Trojan War. Ulysses tells the tale of his fatal final voyage, where he left his home and family to sail to the end of the Earth. He equated life as a pursuit of knowledge that humanity can attain through effort, and in his search God sank his ship outside of Mount Purgatory. This symbolizes the inability of the individual to carve out one's own salvation. Instead, one must be totally subservient to the will of God and realize the inability of one to be a God unto oneself. Guido da Montefeltro recounts how his advice to Pope Boniface VIII resulted in his damnation, despite Boniface's promise of absolution. (Cantos XXVI and XXVII)
Bolgia 9: A sword-wielding devil hacks at the sowers of discord. As they make their rounds the wounds heal, only to have the devil tear apart their bodies again. Muhammad tells Dante to warn the schismatic and heretic Fra Dolcino. (Cantos XXVIII and XXIX)
Bolgia 10: Groups of various sorts of falsifiers (alchemists, counterfeiters, perjurers, and impersonators) are afflicted with different types of diseases. (Cantos XXIX and XXX)

Satan is trapped in the frozen central zone in the Ninth Circle of Hell, Inferno, Canto 34.The Ninth Circle is ringed by classical and Biblical giants. The giants are standing either on, or on a ledge above, the ninth circle of Hell, and are visible from the waist up at the ninth circle of the Malebolge. The giant Antaeus lowers Dante and Virgil into the pit that forms the ninth circle of Hell. (Canto XXXI)

Ninth Circle. Traitors, distinguished from the "merely" fraudulent in that their acts involve betraying one in a special relationship to the betrayer, are frozen in a lake of ice known as Cocytus. Each group of traitors is encased in ice to a different depth, ranging from only the waist down to complete immersion. The circle is divided into four concentric zones:
Zone 1: Caïna, named for Cain, is home to traitors to their kindred. The souls here are immersed in the ice up to their necks. (Canto XXXII)
Zone 2: Antenora is named for Antenor of Troy, who according to medieval tradition betrayed his city to the Greeks. Traitors to political entities, such as party, city, or country, are located here. Count Ugolino pauses from gnawing on the head of his rival Archbishop Ruggieri to describe how Ruggieri imprisoned and starved him and his children. The souls here are immersed at almost the same level as those in Caïna, except they are unable to bend their necks. (Cantos XXXII and XXXIII)
Zone 3: Ptolomæa is probably named for Ptolemy, the captain of Jericho, who invited Simon Maccabaeus and his sons to a banquet and there killed them. Traitors to their guests are punished here. Fra Alberigo explains that sometimes a soul falls here before the time that Atropos (the Fate who cuts the thread of life) should send it. Their bodies on Earth are immediately possessed by a fiend. The souls here are immersed so much that only half of their faces are visible. As they cry, their tears freeze and seal their eyes shut- they are denied even the comfort of tears. (Canto XXXIII)
Zone 4: Judecca, named for Judas the Iscariot, Biblical betrayer of Christ, is for traitors to their lords and benefactors. All of the sinners punished within are completely encapsulated in ice, distorted to all conceivable positions. Dante and Virgil, with no one to talk to, quickly move on to the center of hell. Condemned to the very center of hell for committing the ultimate sin(Treachery against God) is Satan, who has three faces, one red, one black, and one a pale yellow, each having a mouth that chews on a prominent traitor. Satan himself is represented as a giant, terrifying beast, weeping tears from his six eyes, which mix with the traitors' blood sickeningly. He is waist deep in ice, and beats his six wings as if trying to escape, but the icy wind that emanates only further ensures his imprisonment (as well as that of the others in the ring). The sinners in the mouths of Satan are Brutus and Cassius in the left and right mouths, respectively, who were involved in the assassination of Julius Caesar (an act which, to Dante, represented the destruction of a unified Italy), and Judas Iscariot (the namesake of this zone) in the central, most vicious mouth, who betrayed Jesus. Judas is being administered the most horrifying torture of the three traitors, his head in the mouth of Lucifer, and his back being forever skinned by the claws of Lucifer. (Canto XXXIV) What is seen here is a perverted trinity. Satan is impotent, ignorant, and evil while God can be attributed as the opposite: all powerful, all knowing, and good.
The two poets escape by climbing down the ragged fur of Lucifer, passing through the center of the earth, emerging in the other hemisphere just before dawn on Easter Sunday beneath a sky studded with stars.

Purgatorio
Having survived the depths of Hell, Dante and Virgil ascend out of the undergloom, to the Mountain of Purgatory on the far side of the world (in Dante's time, it was believed that Hell existed underneath Jerusalem). The Mountain is on an island, the only land in the Southern Hemisphere. At the shores of Purgatory, Dante and Virgil are attracted by a musical performance by Casella, but are reprimanded by Cato, a pagan who has been placed by God as the general guardian of the approach to the mountain. The text gives no indication whether or not Cato's soul is destined for heaven: his symbolic significance has been much debated. (Cantos I and II).

Dante gazes at Mount Purgatory in an allegorical portrait by an unknown artist of the 16th century.Dante starts the ascent on Mount Purgatory. On the lower slopes (designated as "ante-Purgatory" by commentators) Dante meets first a group of excommunicates, detained for a period thirty times as long as their period of contumacy. Ascending higher, he encounters those too lazy to repent until shortly before death, and those who suffered violent deaths (often due to leading extremely sinful lives). These souls will be admitted to Purgatory thanks to their genuine repentance, but must wait outside for an amount of time equal to their lives on earth (Cantos III through VI). Finally, Dante is shown a beautiful valley where he sees the lately-deceased monarchs of the great nations of Europe, and a number of other persons whose devotion to public and private duties hampered their faith (Cantos VII and VIII). From this valley Dante is carried (while asleep) up to the gates of Purgatory proper (Canto IX).

The gate of Purgatory is guarded by an angel who uses the point of his sword to draw the letter "P" (signifying peccatum, sin) seven times on Dante's forehead, abjuring him to "wash you those wounds within." The angel uses two keys, gold and silver, to open the gate and warns Dante not to look back, lest he should find himself outside the gate again, symbolizing Dante having to overcome and rise above the hell that he has just left and thusly leaving his sinning ways behind him.

From there, Virgil guides the pilgrim Dante through the seven terraces of Purgatory. These correspond to the seven deadly sins, each terrace purging a particular sin in an appropriate manner. Those in purgatory can leave their circle whenever they like, but essentially there is an honor system where no one leaves until they have corrected the nature within themselves that caused them to commit that sin. Souls can only move upwards and never backwards, since the intent of Purgatory is for souls to ascend towards God in Heaven, and can ascend only during daylight hours, since the light of God is the only true guidance.

The Terraces of Purgatory
On the first three terraces of Purgatory are purified those whose sins were caused by perverted love, love directed toward vice instead of God.

Dante's meeting with Matelda, lithograph by Cairoli (1889)First Terrace. The proud are purged by carrying giant stones on their backs, unable to stand up straight (Cantos X through XII). This teaches the sinner that pride puts weight on the soul and it is better to throw it off. Furthermore, there are carvings of historical and mythological examples of pride to learn from. With the weight on one's back, one cannot help but see this carved pavement and learn from it. At the ascent to the next terrace, an angel clears a letter P from Dante's head. This process is repeated on each terrace. Each time a P is removed, Dante's body feels lighter, because he becomes less and less weighed down from sin.
Second Terrace. The envious are purged by having their eyes sewn shut and wearing clothing that makes the soul indistinguishable from the ground (Cantos XIII through XV). This is akin to a falconer's sewing the eyes of a falcon shut in order to train it. God is the falconer and is training the souls not to envy others and to direct their love towards Him.
Third Terrace. The wrathful are purged by walking around in acrid smoke (Cantos XV through XVII). Souls correct themselves by learning how wrath has blinded their vision, impeding their judgment.
On the fourth terrace we find sinners whose sin was that of deficient love—that is, sloth or acedia.

Fourth Terrace. The slothful are purged by continually running (Cantos XVIII and XIX). Those who were slothful in life can only purge this sin by being zealous in their desire for penance.
On the fifth through seventh terraces are those who sinned by loving good things, but loving them in a disordered way.

Fifth Terrace. The avaricious and prodigal are purged by lying face-down on the ground, unable to move (Cantos XIX through XXI). Excessive concern for earthly goods—whether in the form of greed or extravagance—is punished and purified. The sinner learns to turn his desire from possessions, power or position to God. It is here that the poets meet the soul of Statius, who has completed his purgation and joins them on their ascent to paradise.
Sixth Terrace. The gluttonous are purged by abstaining from any food or drink (Cantos XXII through XXIV). Here, the soul's desire to eat a forbidden fruit causes its shade to starve. To sharpen the pains of hunger, the former gluttons on this terrace are forced to pass by cascades of cool water without stopping to drink. (Considering Dante's use of Greek myth, this may be inspired by Tantalus.)
Seventh Terrace. The lustful are purged by burning in an immense wall of flames (Cantos XXV through XXVII). All of those who committed sexual sins, both heterosexual and homosexual, are purified by the fire. Excessive sexual desire misdirects one's love from God and this terrace is meant to correct that. In addition, perhaps because all sin has its roots in love, every soul who has completed his penance on the lower six cornices must pass through the wall of flame before ascending to the Earthly Paradise. Here Dante, too, must share the penance of the redeemed as the last "P" is removed from his forehead.

Dante's meeting with Beatrice, by John William WaterhouseThe ascent of the mountain culminates at the summit, which is in fact the Garden of Eden (Cantos XXVIII through XXXIII). This place is meant to return one to a state of innocence that existed before the sin of Adam and Eve caused the fall from grace. Here Dante meets Matilda (in Dante's spelling "Matelda," representing "Lady Philosophy," the object of Dante's affection after Beatrice's death and his embodiment of wisdom), a woman of grace and beauty who prepares souls for their ascent to heaven. With her Dante witnesses a highly symbolic procession that may be read as an allegorical masque of the Church and the Sacrament. One participant in the procession is Beatrice, whom Dante loved in childhood, and at whose request Virgil was commissioned to bring Dante on his journey.

Virgil, as a pagan, is a permanent denizen of Limbo, the first circle of Hell, and may not enter Paradise; he vanishes. Beatrice then becomes the second guide (accompanied by an extravagant procession), and will accompany Dante in his vision of Heaven.

Dante drinks from the River Lethe, which causes the soul to forget past sins, and then from the River Eunoë, which effects the renewal of memories of good deeds. Thus purified, souls can direct their love fully towards God to the best of their inherent capability to do so. They are then ready to leave Mount Purgatory for Paradise. Being totally purged of sin, Purgatorio ends with Dante's vision aimed at the stars, anticipating his ascent to heaven.

Paradiso

After an initial ascension (Canto I), Beatrice guides Dante through the nine spheres of Heaven. These are concentric and spherical, similar to Aristotelian and Ptolemaic cosmology. Dante admits that the vision of heaven he receives is the one that his human eyes permit him to see. Thus, the vision of heaven found in the Cantos is Dante's own personal vision, ambiguous in its true construction. The addition of a moral dimension means that a soul that has reached Paradise stops at the level applicable to it. Souls are allotted to the point of heaven that fits with their human ability to love God. Thus, there is a heavenly hierarchy. All parts of heaven are accessible to the heavenly soul. That is to say all experience God but there is a hierarchy in the sense that some souls are more spiritually developed than others. This is not determined by time or learning as such but by their proximity to God (how much they allow themselves to experience Him above other things). It must be remembered in Dante's schema that all souls in Heaven are on some level always in contact with God.

The Spheres of Heaven
The nine spheres are:

First Sphere. The sphere of the Moon is that of souls who abandoned their vows (Cantos II through V). Dante meets Piccarda, sister of Dante's friend Forese Donati, who died shortly after being forcibly removed from her convent. Beatrice discourses on the freedom of the will, and the inviolability of sacred vows.
Second Sphere. The sphere of Mercury is that of souls who did good out of a desire for fame (Cantos V through VII). Justinian recounts the history of the Roman Empire. Beatrice explains to Dante the atonement of Christ for the sins of humanity.
Third Sphere. The sphere of Venus is that of souls who did good out of love (Cantos VIII and IX). Dante meets Charles Martel of Anjou, who decries those who adopt inappropriate vocations, and Cunizza da Romano. Folquet de Marseilles points out Rahab, the brightest soul among those of this sphere.
Fourth Sphere. The sphere of the Sun is that of souls of the wise (Cantos X through XIV). Dante is addressed by St. Thomas Aquinas, who recounts the life of St. Francis of Assisi and laments the corruption of his own Dominican Order. Dante is then met by St. Bonaventure, a Franciscan, who recounts the life of St. Dominic, and laments the corruption of the Franciscan Order. Finally, Aquinas introduces King Solomon, who answers Dante's question about the doctrine of the resurrection of the body.
Fifth Sphere. The sphere of Mars is that of souls who fought for Christianity (Cantos XIV through XVIII). The souls in this sphere form an enormous cross. Dante speaks with the soul of his ancestor Cacciaguida, who praises the former virtues of the residents of Florence, recounts the rise and fall of Florentine families and foretells Dante's exile from Florence, before finally introducing some notable warrior souls (among them Joshua, Roland, Charlemagne, and Godfrey of Bouillon).
Sixth Sphere. The sphere of Jupiter is that of souls who personified justice (Cantos XVIII through XX).
Seventh Sphere. The sphere of Saturn is that of the contemplative (Cantos XXI and XXII). For example, monks are found here.
Eighth Sphere. The sphere of fixed stars is the abode of all the blessed (Cantos XXII through XXVII). Here, Dante is tested on faith by Saint Peter, hope by Saint James, and love by Saint John the Evangelist. Dante justifies his medieval belief in astrology, that the power of the constellations is drawn from God.
Ninth Sphere. The Primum Mobile ("first moved" sphere) is the abode of angels (Cantos XXVII through XXIX).

Dante and Beatrice gaze upon the highest Heaven; from Gustave Doré's illustrations for the Divine Comedy, Paradiso, Canto 31Beatrice leaves Dante with Saint Bernard who prays to Mary on behalf of Dante and Dante is allowed to see both Jesus and Mary. From the Primum Mobile, Dante ascends to a region beyond physical existence, called the Empyrean (Cantos XXX through XXXIII). Here he comes face-to-face with God Himself, and is granted understanding of the Divine and of human nature. His vision is improved beyond that of human comprehension. God appears as three equally large circles within each other representing the Father, the Son and the Holy Spirit with the essence of each part of God, separate yet one. The book ends with Dante trying to understand how the circles fit together, how the Son is separate yet one with the Father but as Dante put it "that was not a flight for my wings" and the vision of God becomes equally inimitable and inexplicable that no word or intellectual exercise can come close to explaining what he saw. Dante's soul, through God's absolute love, experiences a unification with itself and all things "but already my desire and my will were being turned like a wheel, all at one speed by the Love that turns the sun and all the other stars."
