The origin of the concept of zombiism stems from Haitian Voodoo culture. The word zombie–in Haitian it is “zombi”–means “spirit of the dead.” Voodoo folklore contends that Bokors, Voodoo priests that were concerned with the study and application of black magic, posessed the ability to ressurrect the deceased through the administration of coup padre–coup padre is a powder that is issued orally, the primary ingredient of which is tetrodoxin, the deadly substance of the notoriously poisonous fou-fou, or “porcupine fish.” According to lengend, “a zombi(e) is someone who has annoyed his or her family and community to the degree that they can no longer stand to live with this person. They respond by hiring a Bokor..to turn them into a zombi(e).” (Keegan, www.flmnh.ufl.edu)
Once they had been issued the coup padre, the subjects being prepared for their descent into zombidom would appear to die insofar as their heart rate would slow to a near stop, their breathing patterns would be greatly subdued and their body temperature would significantly decrease. The public, thinking that the person was dead, would bury him/ her as if they were a corpse. They would then be exhumed, still alive, by the Bokor and, although their physicality remained intact, their memory would be erased and they would be transformed into mindless drones.
“Though still living, they remain under the Bokor’s power until the Bokor dies.” (Keegan,www.flmnh.ufl.edu)
