Necronomicon
The Necronomicon is a fictional book of magic created by the horror writer H. P. Lovecraft. It is a Greek-sounding word commonly translated as "book of dead names".  It is pronounced "neck-ro-nom-ih-kon".  Like most of his ideas, the Necronomicon came to Lovecraft in his dreams.  Lovecraft let his friends write stories about the Necronomicon.  Eventually, fake Necronomicons were written.
