At the beginning of this century, the sewer of Paris was still a mysterious place. Mud can never enjoy a good fame; but in this case its evil renown reached the verge of the terrible. Paris knew, in a confused way, that she had under her a terrible cavern. People talked of it as of that monstrous bed of Thebes in which swarmed centipedes fifteen long feet in length, and which might have served Behemoth for a bathtub. The great boots of the sewermen never ventured further than certain well-known points. We were then very near the epoch when the scavenger’s carts, from the summit of which Sainte-Foix fraternized with the Marquis de Créqui, discharged their loads directly into the sewer. As for cleaning out⁠—that function was entrusted to the pouring rains which encumbered rather than swept away. Rome left some poetry to her sewer, and called it the Gemoniae; Paris insulted hers, and entitled it the Polypus-Hole. Science and superstition were in accord, in horror. The Polypus hole was no less repugnant to hygiene than to legend.
