The readings.
Listen, we all know the readings have gotten progressively easier as they've become more and more modern, but with the story of Landval and the Lay of Chevefoil, the ease of reading has become increased dramatically. Then we come to Dante's inferno. With the inferno the ease fo reading has been set back to Iliad levels, at least in my opinion. Its over saturated with heavy language, extreme similes, and the pettiness of the greeks. My belief is that Dante resumes this over saturation as a way to model the greeks similar way of being extreme about everything, following in the steps of the Romans for stealing works of the greeks, and following in his hero, Virgil's, footsteps.
