Many people today are entranced by the idea of speaking with the dead or else immersing themselves in vampire tales and wonder. What most people don’t realize is how old and revered these stories really are. Within this work Calmet attempts to show where the idea of spirits and apparitions comes from and then within the second part of the main work where the idea and history of the vampire itself comes from. This work simply is not just a history text of ancient religious beliefs but also explains the thinking and beliefs that surrounded the spirits and vampires in the day and age when Calmet wrote this work.
