Calmet, Augustin
"The Phantom World; or, The philosophy of spirits, apparitions, &c, &c." by Calmet is a treatise published in 1751. This extensive investigation into the occult examines apparitions of angels, demons, and spirits, along with vampires, revenants, and the dead returning from graves. Spanning 115 chapters across two volumes, Benedictine monk Dom Calmet applies scientific methods to analyze biblical accounts, mythology, and historically documented cases of witchcraft, possession, hauntings, and supernatural phenomena, distinguishing truth from fraud in pre-modern occult claims.
