and a summary of each level or ring?
gpt
Dante is a pretty cool guy whose beloved Beatrice bites the dust is taken to the afterlife. Hell is Dante's first stop.

* Level 1: Limbo. Unvirtuous Pagans and the unbaptized. Didn't get eternal punishment, but didn't get reward because they never accepted Jesus. Lots of Classical characters are chillin' in Limbo. Dante continues, guided by the Roman poet Virgil.

* Level 2: Lust. Lustful souls are blown about by eternal strong winds representing the power of lust to blow us about in life. He meets Cleopatra and Paris and Helen of Troy and other lustful figures. 
 
* Level 3: Gluttony. Cerberus stands guard over the gluttonous. They lie in slush brought down by relentless icy rains. They are meant to represent the cold, empty, meaningless sensuality of their lives. They are blind and unaware of their surroundings.
 
* Level 4: Greed. The greedy and miserly are meant to push large weights around (sometimes depicted as large bags of money) and joust using these. The god of wealth Pluto, or Plutus, watches over them. 

* Level 5: Anger. The angry/wrathful are punished by being forced to fight one another for space on the surface of the river. The downtrodden lie on the bed of the river surrounded by inky water. 

* After this, the punishments of active rather than passive sins are carried out in the city of Dis. The walls are guarded by fallen angels, who refuse to let Dante in. An angel from heaven comes and tells them to let Dante in and they do. 

* Level 6: Heresy. The heretics are trapped in flaming tombs. Two of them chat with Dante.

* Level 7: Violence. Divided into three rings. 1). Outer ring: Violent to people and property. Forced to stand in a river of boiling blood and fire. The more violent you are, the deeper you stand. Alexander the Great is dipped up to his eyebrows. 2). Middle ring: Suicides. Transformed into thorny bushes and trees. These trees are the only ones who will not be resurrected for the final judgment. They renounced their bodies by killing themselves. 3). Inner ring: Violent against God, usurpers, and sodomites. The inner ring is a desert of flaming sand with fiery flakes falling from the sky. Blasphemers lie on the sand. Usurpers sit. Sodomites wander in groups. 

* Level 8: Fraud. 10 pockets of stone are cut into one large space. Bridges connect them. They are for different types of fraud. 1). "Panderers and Seducers" are whipped by demons and forced to march endlessly. 2). Flatterers are forced to sit in human poo, meant to represent the useless words they produced. 3). Those who commit simony have their heads stuffed into the rock and flames burn the soles of their feet. 4). Sorcerers and false prophets have their heads turned around and walk backwards everywhere. 5). Corrupt politicians are immersed in boiling pitch, supposed to represent their sticky nature and dark words. 6). Hypocrites walk around with robes made of lead covered in gold, meant to represent their gilded nature. 7). Thieves are guarded by a dragon-monster and are tormented by snakes and lizards. 8). Fraudulent advisors burn in individual flames. 9). A demon uses a sword to wound and chop up the "Sowers of Discord". 10). Various falsifiers are subjected to various diseases.

* Level 9: Treachery. Divided into 4 concentric circles. 1).Treachery against family ties, the punished are covered in ice up to their faces. 2). Traitors to political entities, Dante encounters a man gnawing on the head of a former compatriot. 3). Traitors to the guest-host relationship. Forced to lie flat in the ice with everything but their faces covered. 4). Traitors to their lords and masters. Punished by being covered completely in ice, in various distorted positions. 

* At the center of Hell is Satan, and his domain is those who commit a personal treachery against God. A beast with three heads and six wings, he is trapped in ice. He beats his wings to try and free himself, and constantly cries from his six eyes. Brutus and Cassius are in the left and right mouths. In the center mouth is Judas Iscariot, being constantly chewed by Satan and having his back flayed by his claws. It's portrayed as an inverted trinity.

Dante descends below Satan through the center of the Earth to Purgatory and the narrative continues.
