Cantos 23-25

Canto 23
"Not like his mere companion, but like his child" (pg. 237). It is interesting that Dante compares Virgil to God in this level of Hell. This section of Hell is reserved for those who spent their lives as hipocrites. It can be argued that the whole purpose of this text is to try to scare everyone into converting to the "true" religion, but now the author is going against that agenda by putting someone who is in Hell on an even higher level than God. Dante puts everyone in Hell because they aren't perfect, but when he himself isn't perfect, it's considered to be normal.
Canto 24
"and tears the mist and strikes at every White" (pg. 255). White is usually symbolic of purity and innocence, but in this part of Hell, it is something that brings even more punishment on the sinners. This also plays into the level of hypocrites by showing that something that seems pure and wonderful before death can serve to punish you after you die.
Canto 25
"a serpent darted forward that had six feet" (pg. 261). In the Bible, the serpent that appears to Adam and Eve in the Garden of Eden originally has feet until it is cursed by God to crawl in the dust. This serpent isn't cursed to slither on the ground because it is in a place where everything is considered evil, so it is equally as cursed as everyone else. It is almost like a backwards ressurection. The serpent starts out evil, then it's legs are taken away because of its sins while it is on Earth. Then, when it returns to where it came from, its legs are restored.
