Level with the soles of the feet, in front and fairly far away, is a hell called Gehenna containing shameless women who centered all their pleasure on committing adultery. They regarded adultery as not just acceptable but honorable and lured the unblemished and innocent into it under various high-minded guises.
A sort of fiery glow appears there, like the one that a large conflagration would cast in the air. There is also a blast of heat, which I was able to feel through the warmth that spread from there to my face. And an odor drifts out that resembles the smell of singed bones and hair.
Sometimes this hell turns into a mass of loathsome snakes that bite the inhabitants. Once bitten they long for death, but they cannot die.
Some women released from the place came to me and said it was hot there. They reported that when they are allowed to approach a certain community of good spirits, the heat turns into intense cold. The temperature, they said, then fluctuates between extremes of blazing heat and freezing cold, which also tormented them miserably.
They have intervals during which they are aroused and aflame with lust; but conditions change for them, as noted.
