At the Chatelet de Paris there was a long, wide cellar, which was eight feet below the level of the Seine. It had neither windows nor ventilators, the only opening was the door; men could enter, but not air. For a ceiling the cellar had a stone arch, and for a floor, ten inches of mud. It had been paved with tiles, but, under the oozing of the waters, the pavement had rotted and broken up. Eight feet above the floor, a long massive beam crossed this vault from side to side; from this beam there hung, at intervals, chains three feet in length, and at the end of these chains there were iron collars. Men condemned to the galleys were put into this cellar until the day of their departure for Toulon. They were pushed under this beam, where each had his irons swinging in the darkness waiting for him. The chains, those pendent arms, and the collars, those open hands, seized these wretches by the neck. They were riveted, and they were left there. The chain being too short, they could not lie down. They remained motionless in this cave, in this blackness, under this timber, almost hung, forced to monstrous exertions to reach their bread or their pitcher, the arch above their heads, the mud up to their knees, their excrement running down their legs, collapsing with fatigue, their hips and knees giving way, hanging by their hands to the chain to rest, unable to sleep except standing, and constantly woken up by the strangling of the collar: some did not wake up. In order to eat, they had to drag their bread, which was thrown into the mud, up the leg with a heel, to within reach of the hand. How long did they stay this way? A month, two months, six months sometimes; one remained a year. It was the antechamber to the galleys. Men were put there for stealing a hare from the king.
