Arthur Machen
Around 1890 Machen began to publish in literary magazines, writing stories influenced by the works of Robert Louis Stevenson, some of which used gothic or fantastic themes. This led to his first major success, "The Great God Pan". It was published in 1894 by John Lane in the noted Keynotes Series, which was part of the growing aesthetic movement of the time. Machen's story was widely denounced for its sexual and horrific content and consequently sold well, going into a second edition.

King in interviews and in the book itself said the story was inspired by Arthur Machen’s "The Great God Pan" stating: "Not Lovecraft; it’s a riff on Arthur Machen’s 'The Great God Pan,' which is one of the best horror stories ever written. Maybe the best in the English language. Mine isn’t anywhere near that good, but I loved the chance to put neurotic behavior—obsessive/compulsive disorder—together with the idea of a monster-filled macroverse."
