Canto 11&12

Canto 11
1. "Inscribed: I hold Pope Anastasius" (pg. 109). It is ironic that the Pope is one of the most prominent figure heads of the Chrisitan religion and he still ends up in Hell. The author could be using this to serve as a warning to the reader that they should be careful with what they do with their life so that they don't enter in to the same fate.
2. "But please, could we retrace our path" (pg. 113). This is one of the first times where Dante actually asks that they could turn around rather than continuing on their journey. This scene is meant to show the reader the horrors that he is facing as well as provide as a contrast between Dante and the old heroes. Dante is finding it hard to continue and he has a guide. The heroes were able to go into Hell and come back out again with a pretty small amount of help.
Canto 12
1. "love: the force that has brought chaos back" (pg. 121). Love is not usually thought of as something that brings about chaos, but rather peace, joy and happiness. The author's suggestion that love brings turmoil could be referring to the suffering that is being felt by those who defied God. Love is something that is supposed to be posessed by all of God's servants, so it is the one thing that will always cause regret and anguish in those who fell from favor.
2. "rise out of the blood more than its guilt makes lawful" (pg. 123). This reinforces the idea that there is pity in Hell. Unfortunately for the sinful, that pity isn't enough to lessen the suffering very much. In this case, a soul could find some relief from being boiled, but if they try to take advantage of the mercy too much, they will be punished by the sting of the arrows.
