I wish I got that reference.

"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 (pimps) and seducers march in separate lines in opposite directions, whipped by demons.
* Bolgia 2: Flatterers also exploited other people, this time using language. They are steeped in human excrement, which represents the words they produced. Alessio Interminei of Lucca and Thaïs are seen here.[37] (Canto XVIII).
* Bolgia 3: Dante now forcefully expresses[39] his condemnation of those who committed simony.
* Bolgia 4: Sorcerers, astrologers, and false prophets here have their heads twisted around on their bodies backward, so that they "found it necessary to walk backward, / because they could not see ahead of them.
* Bolgia 5: Corrupt politicians (barrators) are immersed in a lake of boiling pitch, which represents the sticky fingers and dark secrets of their corrupt deals.
* Bolgia 6: In the sixth Bolgia, the poets find the hypocrites listlessly walking along wearing gilded lead cloaks, which represent the falsity behind the surface appearance of their actions – falsity that weighs them down and makes spiritual progress impossible for them.
* Bolgia 7: Two cantos are devoted to the thieves, who are guarded by the centaur Cacus who has a fire-breathing dragon on his shoulders and snakes covering his equine back (in Roman mythology, Cacus was not a centaur but a monstrous fire-breathing giant slain by Heracles).
* Bolgia 8: Two further cantos are devoted to the fraudulent advisers or evil councillors, who are concealed within individual flames.
* Bolgia 9: In the ninth Bolgia, a sword-wielding demon hacks at the sowers of discord, dividing parts of their bodies as in life they divided others.
* Bolgia 10: In the final Bolgia, various sorts of falsifiers (alchemists, counterfeiters, perjurers, and impersonators), who are a "disease" on society, are themselves afflicted with different types of diseases."
