Inferno
Dante Alighieri
the punishment that shows the sin instead of punishing it from outside, like the tempest that carries the lustful (canto V), the order of the circles that Virgil draws (canto XI), the soothsayers with twisted heads (canto XX), the lead cloaks of the hypocrites (canto XXIII), the severed head of Bertran de Born, the only time the word contrapasso appears (canto XXVIII) and the Lucifer who chews the traitors (canto XXXIV).
