Necronomicon Quoted
Abdul Alhazred, the mad poet of Sanaá — The Cthulhu Mythos · H. P. Lovecraft
The most famous book that does not exist. A grimoire of pre-human history and summoning rites, surviving in a handful of guarded copies, quoted just often enough to convince generations of readers it was real.
Unaussprechlichen Kulten Quoted
Friedrich Wilhelm von Junzt — The Cthulhu Mythos · Robert E. Howard
A German study of surviving secret cults, printed in Düsseldorf in 1839. Its author was strangled six months later in a locked room, and the manuscript of his second book was torn to shreds.
