Traité sur les apparitions des esprits et sur les vampires ou de revnants. A 1700's treatise surfaced two centuries ago regarding the supernatural and scientific phenomenon that plagued Europe in an era when Magic, witchcraft, instances of haunting, and even cases of vampires were recorded in judicial and imperial documentation. It was during the age of reason when a Black Monk from the Benedictine Order of the 18th century, penned a work that would become one of the most influential and controversial works of his time. A plethora of cases regarding events in the supernatural had plagued mankind with fear and mystery throughout history, many inhabitants to the regions of Europe came under an epidemic of social hysteria which stemmed from reports of corpses rising from their graves, killing and sucking the blood of victims inhabiting small villages or visitations and the haunting of ghosts, evil spirits and demons. The Black Monk, Abbot Don Augustin Calmet tasked himself with the study of these real and historically documented reports for the purpose of providing the public with the rules to determine a claim's legitimacy through philosophical reasoning of religious and scientific examination that was approved by the King of France in 1746. This work provides an in-depth look into the history of most superstitions, mythologies, and the analysis of events depicted in the ancient texts of various religions and historically renowned cases. Calmet lays out the rules for determining the fraudulence of purported claims and distinguishes them from what may soundly be considered real at the time, providing a "how to" manual when dealing with or investigating occult matters in witchcraft, ghosts, vampires and demonic possessions.
