Cantos 6-12

Agony, none is so repellent." He said:
"Your city, so full of envy that the sack
Spills over, held me once when I enjoyed

I thought this passage was ironic in that Ciacco, who is in hell, speaks of a city "so full of envy,"Here's Dante who is traveling through hell, not receiving its wrath, yet it's Ciacco, in hell, who speaks of envy elsewhere. Furthermore, Dante is under the assumption he's going to heaven so his path is already laid out to be free of punishment. Because Ciacco makes this statement, it puts forth the idea about Dante's hometown and past.

Canto 8, line 6-8
The eye could barely catch it. I turned to face
My sea of knowledge and said, Oh Master, say:

It's interesting to see not only the journey of Dante through hell, but also his journey as a person. Dante began his journey at the bottom of the mountain, seemingly quite confident, yet equally lost. Above, we see that Dante has become the
"Gus" on "The Inferno," asking relaying countless, unanswerable questions toward Virgil. Although not necessarily arrogant before, Dante has morphed into a very dependent man, weak and unsure of much. This is seen by his excess fainting and dependence on Virgil. It'll be interesting to see how Dante continues to change throughout, whether he'll really find himself or just become more lost and unaware.
