In course of time the captain of the men-at-arms came to tell me that he was under orders to take me under the Leads. Without a word I followed him. We went by gondola, and after a thousand turnings among the small canals we got into the Grand Canal, and landed at the prison quay. After climbing several flights of stairs we crossed a closed bridge which forms the communication between the prisons and the Doge's palace, crossing the canal called Rio di Palazzo. On the other side of this bridge there is a gallery which we traversed. We then crossed one room, and entered another, where sat an individual in the dress of a noble, who, after looking fixedly at me, said, "E quello, mettetelo in deposito:" This man was the secretary of the Inquisitors, the prudent Dominic Cavalli, who was apparently ashamed to speak Venetian in my presence as he pronounced my doom in the Tuscan language. Messer-Grande then made me over to the warden of The Leads, who stood by with an enormous bunch of keys, and accompanied by two guards, made me climb two short flights of stairs, at the top of which followed a passage and then another gallery, at the end of which he opened a door, and I found myself in a dirty garret, thirty-six feet long by twelve broad, badly lighted by a window high up in the roof. I thought this garret was my prison, but I was mistaken; for, taking an enormous key, the gaoler opened a thick door lined with iron, three and a half feet high, with a round hole in the middle, eight inches in diameter, just as I was looking intently at an iron machine. This machine was like a horse shoe, an inch thick and about five inches across from one end to the other. I was thinking what could be the use to which this horrible instrument was put, when the gaoler said, with a smile, "I see, sir, that you wish to know what that is for, and as it happens I can satisfy your curiosity. When their excellencies give orders that anyone is to be strangled, he is made to sit down on a stool, the back turned to this collar, and his head is so placed that the collar goes round one half of the neck. A silk band, which goes round the other half, passes through this hole, and the two ends are connected with the axle of a wheel which is turned by someone until the prisoner gives up the ghost, for the confessor, God be thanked! never leaves him till he is dead." "All this sounds very ingenious, and I should think that it is you who have the honour of turning the wheel." He made no answer, and signing to me to enter, which I did by bending double, he shut me up, and afterwards asked me through the grated hole what I would like to eat. "I haven't thought anything about it yet," I answered. And he went away, locking all the doors carefully behind him.
