"History of the Necronomicon" is a short text written by H. P. Lovecraft in 1927, and published in 1938. It describes the origins of the fictional book of the same name: the occult grimoire Necronomicon, a now-famous element of some of his stories. The short text purports to be non-fiction, adding to the appearance of 'pseudo-authenticity' which Lovecraft valued in building his Cthulhu Mythos oeuvre. Accordingly, it supposes the history of the Necronomicon as the inspiration for Robert W. Chambers' The King in Yellow, which concerns a book that overthrows the minds of those who read it.
