Augustin Calmet's work, The Phantom World, overviews a rich and varied selection of supernatural tales and beliefs from the stance of the logician. The author compiles testimonies from different places such as Hungary, Poland, Peru, and England and provides his stories with illustrations by famous authors. He seeks to understand the truth behind the stories. For example, what made people believe in good and bad angels, magic, apparitions, vampires, witchcraft, possession by demons, and other mystical stories.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
