Thirty-second Canto
Dante feels the need to invoke the Muses*, to help him describe the horror and the terrifying images of the ninth circle more solemnly. In fact, treason is the worst of the sins, because it means to harm those who loved you the most, or saints and benefactors. Dante wishes they were never born as humans, but as animals (goats and sheep).
While the two poets were being deposed onto the bottom of the pit, someone was crying nearby:
“Beware, do not step on the heads of those who once were your siblings”.
Dante realizes they are walking on an icy lake (Cocytus), as seamless as glass, inside an enormous dark cave. The poet highlights the thickness of that ice layer**.
The souls of the damned were entirely stuck in that ice, except their head (which was face downward), as frogs get their muzzle out of the water. That circle was nothing but teeth chattering (likened to the sound of storks) and silent tears.
The contrappasso is clear: as in life their heart was as cold as ice, that they violated the most sacred bounds of trust, now traitors are stuck in a frozen lake.
Two damned were so close, that their hair were entangled with one other. They couldn't speak with Dante, and their icy tears would clump their eyelids. Because of that, they got upset and banged their head against one another, like rams do.
Another damned, (Alberto Camicione de Pazzi***) whose ears had been severed by the ice, yells at him:
“why do you stare?” He tells him those two were the counts Alberti from Mangona, two brothers who killed one another, in life. They are in the first zone of the ninth circle, called Caina (named after Cain who killed Abel), because the traitors of the kindred are punished there; and nobody, not even Mordred, or Focaccia or Sassolo Mascheroni deserve to be there more than those brothers. Dante felt so much sorrow, watching all that suffering, those frozen faces, and was freezing himself. Unwillingly, he steps on a damned, who cries
“Why did you step on me? If you aren't here to harden my punishment for my treason in Montaperti, why are you here?”.
That damned sounded familiar to Dante; so he reveals him he was a living man and a poet, and that he could have cleared his man on Earth (blandishing him to make him disclose his identity). The damned answered harshly:
“I will not tell you my name, your blandishments are worthless in this circle”.
Then Dante furiously grabs him by the neck and threatens him:
“tell me your name, or else I pull you all your hair out”. But the damned was irremovable, disregarding his threats. All of a sudden another damned yelled:
“what's wrong with you, Bocca degli Abati****? Are you barking, besides chattering your teeth?”.
Dante, who was now sure of his identity called him traitor and that he would expose him on Earth. Bocca says he didn't care, but he tells him that he should also mention the fellow traitor who exposed him: it's Buoso da Duera; and other traitors there are Tesauro dei Beccheria, Gianni dei Soldanieri, Ganelon and Tebaldello de' Zambrasi.
Dante is particularly wild over those who betray their own ideals, or their own fatherland: the second zone of the ninth circle is called Antenora after Antenor of Troy, who betrayed his own city, by giving away the statue of Athena to Ulysses and Diomedes. As in life they betrayed their own compatriots or fellow citizens, now they betray and expose one another in hell.
Dante was shocked, by seeing two damned, clinging one above the other; one was mauling his neckline, ravenously eating his brain, in an animalistic fashion. As Tydeus ate Melanippus' brain to avenge Amphiarus. Dante asked that damned who he was, promising him he would clear his name.
* Through a periphrasis he means the Muses: those women that helped Amphion build the walls of Thebes. The very first stanzas are filled with other periphrases, like for example, saying “the language you use to say mom or dad” to mean “childish talk”.
** Dante points out that not even the Danube in Austria or the Don form such a thick layer of ice, in Winter. And with an hyperbole, he says that not even high Alpine mounts (Tambura and Pania) can break the ice layer of Cocytus.
*** Alberto Camicione de' Pazzi betrayed and killed a relative of his, Ubertino de' Pazzi, aided by Carlino de Pazzi, who was still alive, and according to Alberto, he belongs in the ninth circle much more than him; As for the other characters: Napoleone and Alessandro Alberti di Mangona, sons of Alberto were two brothers, who - because of the inheritance and political interests - killed one another in duel, according to the chronicles of the 13th century. Their name is understandable through a periphrasis: the sons of that Alberto from the valley of Bisenzio river (where Mangona is). Mordred is not explicitly mentioned either: "the man whose chest was torn apart by king Arthur" to punish his betrayal; Vanni de' Cancellieri, from Pistoia, nicknamed Focaccia killed a relative of his, Sinisbaldo Cancellieri and this betrayal ignited the hatred between White and Black Guelphs; Sassolo Mascheroni was probably another nobleman who killed his own relatives.
**** Bocca degli Abati was a Guelph who fought on the battlefield of Montaperti (1260), but he was suspected of betraying his fellow Guelphs and this became evident, when he entered Florence triumphally with other Ghibellines. He was defeated with other Ghibellines in the battle of Benevento (1266). He is angry with Buoso da Duera who exposed him, so he exposes him back: Buoso was a Ghibelline who was bribed by the Angevines (by the Frenchmen's silver) to help them arrive in Benevento, so he betrayed his own party. Gianni de' Soldanieri too betrayed his fellow Ghibellines. Tesauro dei Beccheria conspired against his master, Cardinal Ottaviano degli Ubaldini, and was beheaded for his treason in Florence. Ganelon was a character from the poem Chanson de Roland, who betrayed his fellow Franks, selling information to the Saracens. Tebaldello de' Zambrasi was a Ghibelline from Faenza who betrayed a Ghibelline family, the Lambertazzi, by opening the doors of Faenza to the Bolognese family (Geremei), who were Guelphs.
