The Mysteries of the Inquisition and Other Secret Societies of Spain

This title is quite scarce, if not actually rare, at least in English. Published in Europe in the 1840's these woodcut images are from the 1845 American edition, likely the first edition in the U.S. but I am not sure. I am also unsure if these are all the images, as the book was damages and missing few leaves of text. It did not look as though any illustration pages were missing, but the only bibliographic references I found were sketchy so it is hard to tell.

In the preface the translator writes "The following graphic and authentic descriptions of the incredible barbarities and wickedness of the Spanish Inquisition is written by a Roman Catholic. Whilst many of the characters who figure in the following story are fictitious, the author has adhered closely to facts in every thing relating to the usages of the horrid tribunal which he describes. The portrait of the monster is exact, but the drapery is artificial. The immense popularity of the work on the continent of Europe will surprise no one who peruses its pages. They present unquestionably the most thrilling exhibition of the atrocious wickedness of the Inquisition any where recorded, and this exposure is not the less remarkable, because it is offered by a Roman Catholic." The basic plot involves a young priest who is the assistant to the Grand Inquisitor. As the young priest gains influence, it becomes evident that his motives are more than simply to help the inquisitor, help save the souls of those being tortured, or even to help himself. The horrors of the inquisition are detailed throughout the book.
