He was bound differently from the rest, for he had to his leg a chain so long that it was wound all round his body, and two rings on his neck, one attached to the chain, the other to what they call a "keep-friend" or "friend's foot," from which hung two irons reaching to his waist with two manacles fixed to them in which his hands were secured by a big padlock, so that he could neither raise his hands to his mouth nor lower his head to his hands. Don Quixote asked why this man carried so many more chains than the others.
