'This, sir?' said he. 'This, if you would know it, is a rack--a common instrument of torture--used in all the prisons of the empire, the use of which is to extract truth from one who is unwilling to speak except compelled; or, sometimes, when death is thought too slight a punishment, to give it an edge with, just as salt and pepper are thrown into a fresh wound. Some crimes, you must know, were too softly dealt with, were a sharp axe the only instrument employed. Caesar! just bring some wires of a good thickness, and we will try this. Now shall you see precisely how it would fare with your own body, were you on this iron frame and Varus standing where I am. There,--Caesar having in a few moments brought the wires--the body you perceive is confined in this manner.--You observe there can be no escape and no motion. Now at the word of the judge, this crank is turned. Do you see the effect upon the wire? Imagine it your body and you will have a lively idea of the instrument. Then at another wink or word from Varus, these are turned, and you see that another part of the body, the legs or arms as it may be, are subjected to the same force as this wire, which as the fellow keeps turning you see--strains, and straightens, and strains, till--crack!--there!--that is what we call a rack. A most ingenious contrivance and of great use. This is going up within the hour to the hall of the Prefect.' 'It seems,' I remarked, 'well contrived indeed for its object. And what,' I asked, 'are these which stand here? Are they for the same or a similar purpose?' 'Yes--these, sir, are different and yet the same. They are all for purposes of torture, but they vary infinitely in the ingenuity with which they severally inflict pain and death. That is esteemed in Rome the most perfect instrument which, while it inflicts the most exquisite torments, shall at the same time not early, assail that which is a vital part, but, you observe, prolong life to the utmost. Some, of an old-fashioned structure, with a clumsy and bungling machinery--here are some sent to me as useless--long before the truth could be extracted, or much more pain inflicted than would accompany beheading, destroyed the life of the victim. Those which I build--and I build for the State--are not to be complained of in that way. Varus is curious enough, I can assure you, in such things. All these that you see here, of whatever form or make, are for him and the hall of justice. They have been all refitted and repaired--or else they are new.' 'How is it possible,' I asked, 'so many could be required in one place?' 'Surely,' said the master, 'you must just have dropt down in Rome from Britain, or Scythia, or the moon! Didst ever hear of a people called Galilean or Christian? Perhaps the name is new to you.' 'No, I have heard it.'
