Finished with Inferno and in Purgatory now.
I forgot to mention before, but I'm having a blast with the all encompassing syncretism.
The last circle was interesting by how much less horrifying I found it in relation to the eight. I think it's the corporeal and visceral nature of the Malebolge, while a frozen plain has something of the unfathomable in it (and yeah, I got the contrast idea of virtues and the Holy ghost being depicted as fire).
Maybe there is something about horror vs terror in there too? The knowable bad vs the impossible to comprehend?
The descriptions, for such short things, are epic.
