The Necronomicon Ex-Mortis or Naturan Demanto, as portrayed in Equinox (1970 film) and in The Evil Dead (1981 franchise)....

Naturom Demonto, AKA Naturan Demanto, Necronomicon Ex-Mortis, "Ancient Kandarian Book of the Dead", "Book of Ulthar", "Book of Cthulhu", "Book of Evil", "Curses of the Ancient Dead", etc.

Origin: Evil Dead (1981 franchise) as Necronomicon Ex-Mortis and Naturom Demonto; a similar concept has appeared in other films and media

For all intents and purposes, any vaguely "Lovecraftian" cinematic tome of any name that conjures demons or zombies or opens a portal to a hellish "other world" can be considered a version of the Necronomicon Ex-Mortis.


A plot device from the Evil Dead (1981 franchise), said to have been written by one of the "Dark Ones", a Kandarian Demon, in Sumeria at a time when "the seas ran red with blood".

The shooting script for The Evil Dead elaborates on its origins a little more than the film itself: "Excavated from the ruins of Ca'n Dar, the 'Book of the Dead' was one of six volumes of ancient Sumerian burial practices and rites entitled "Naturan Demanto" roughly translated 'Book of the Dead'. It was bound in human flesh, and inked with blood. The other volumes still lost, this particular volume deals with demons and demon resurrection. These are of the Katardi family, meaning those forces believed to inhabit the jungles and woods of man's domain. As legend has it, only the sacred high priests of the Ca'n Dar tribe could possess these books, for they alone could properly control the resurrected demons. It is only through the act of reciting the resurrection passage that these demons would be able to possess the living."

(Similar generic tomes have appeared in other films, and might have their own unique titles and histories, but few of these other "Necronomicons" have their own detailed origin stories or histories.)

  • "I believe I have made a significant find in the Kandarian ruins, a volume of ancient Sumerian burial practices and funerary incantations. It is entitled Naturum Demontum, roughly translated: Book of the Dead. The book is bound in human flesh and inked in human blood. It deals with demons, demon resurrection and those forces which roam the forest and dark bowers of Man's domain. The first few pages warn that these enduring creatures may lie dormant but are never truly dead. They may be recalled to active life through the incantations presented in this book. It is through the recitation of these passages that the demons are given license to possess the living... I know now that my wife has become host to a Kandarian demon. I fear that the only way to stop those possessed by the spirits of the book is through the act of... bodily dismemberment...." - Professor Knowby on audio tape, The Evil Dead
  • "He who has wisdom wonders not of the Beast, for nothing in Hell lives without man's consent. "Woe unto you who would give the Beast form. To contemplate evil is to ask evil home.... It's part werewolf and vampire, demon and ghost. It would tear your throat open then drink your blond, and feast on your still-warm brains...." - Curses of the Ancient Dead (from Cellar Dweller (1988 film))
