Stuck in my mind forever is one image from this painting of purgatory and hell. One character (slightly to the left of the being with the gaping mouth) straddles a huge saw, twice his size. And he works to saw off his arm. (That is exactly how it feels trying to be virtuous even on earth, isn't it? Not that I try that hard.)
P.S. We showed Chester lots of the religious art. He was able to identify St. Christopher and St. Nicholas! So proud.
