Allegory— It seems as though The Divine Comedy is an Allegory for the life of humans. Desperate depravity. God’s grace and repentance of our sins. Living in glory with Him. The Inferno focuses specifically on explaining the depravity of hell, but this can also be applied to the depravity of the human race.
Terza rima – I have John Ciardi’s translation and I quite enjoy the Rhyme Scheme with the pattern of aba, bcb…etc. It flows easier for me in this Rhyming way. I don’t know exactly how it would be different if I didn’t have this rhyme scheme. I imagine it would probably be harder for me to read, in the fact that the lightness of the rhyming would be gone. It would be more depressing.
