When for the third time the fiery wave broke on him, lifting him a little, the child curled himself up and shrank away to the edge of the bed, as if in terror of the flames advancing on him, licking his limbs. A moment later, after tossing his head wildly to and fro, he flung off the blanket. From between the inflamed eyelids big tears welled up and trickled down the sunken, leaden-hued cheeks. When the spasm had passed, utterly exhausted, tensing his thin legs and arms, on which, within forty-eight hours, the flesh had wasted to the bone, the child lay flat, racked on the tumbled bed, in a grotesque parody of crucifixion. (4.3.24)
Not exactly the subtlest religious imagery we’ve ever read, but OK. To start, you’ve got all the flames, which reminds us of Hell, but the "crucifixion" bit at the end is what really gives it away.
