The Great God Pan

The Great God Pan by Arthur Machen (1894)

A scientist performs brain surgery on a young woman to allow her to "see" the god Pan — the primal force behind reality. The experiment unleashes something terrible into Victorian London. Stephen King called it "maybe the best horror story in the English language."

Historical Significance:
Arthur Machen, a Welsh journalist and mystic, published The Great God Pan in 1894 to mixed reviews — one critic called it "an incoherent nightmare of sex and the supernatural." But the novella's influence on horror fiction has been immeasurable. H.P. Lovecraft cited Machen as a primary inspiration for his cosmic horror — the idea that reality conceals something ancient, vast, and terrifying. The story's structure — told through fragments, documents, and multiple perspectives — anticipated Lovecraft's technique. Guillermo del Toro has called Machen one of his favorite authors. The novella experienced a major revival after Stephen King's endorsement and is now recognized as a foundational text of modern horror.
