A More Horrible Pit Trap

I read The Monster of the Prophecy by Clark Ashton Smith the other night, and near the end it had this wonderful little bit:

They came to the final step of the stairway, where, in a vast vault, an abyss whose bottom was not discernible yawned in the center of the floor. On its edge there stood a fantastic sort of windlass on which was wound an immense coil of blackish rope.

The end of this rope was now tied about Alvor's ankles, and he was lowered head downward into the gulf by the inquisitors. The sides were not luminous like those of the stairway, and he could see nothing. But, as he descended into the gulf, the terrible discomfort of his position was increased by sensations of an ulterior origin. He felt that he was passing through a kind of hairy material with numberless filaments that clung to his head and body and limbs like minute tentacles, and whose contact gave rise to an immediate itching. The substance impeded him more and more, till at last he was held immovably suspended as in a net, and all the while the separate hairs seemed to be biting into his flesh with a million microscopic teeth, till the initial itching was followed by a burning and a deep convulsive throbbing more exquisitely painful than the flames of an auto da fe. The poet learned long afterward that the material into which he had been lowered was a subterranean organism, half vegetable, half animal, which grew from the side of the gulf, with long mobile feelers that were extremely poisonous to the touch. But at the time, not the least of the horrors he underwent was the uncertainty as to its precise nature.

After he had hung for quite a while in this agonizing web, and had become almost unconscious from the pain and the unnatural position, Alvor felt that he was being drawn upward. A thousand of the fine thread-like tentacles clung to him and his whole body was encircled with a mesh of insufferable pangs as he broke loose from them. He swooned with the intensity of this pain, and when he recovered, he was lying on the floor at the edge of the gulf, and one of the priests was prodding him with a many-pointed weapon.

Chew on that for a while!
