Arthur Machen was a Welsh man of letters who wrote his most famous work in the late 1890s and early 1900s. While his body of work is wide, he’s perhaps best known for his supernaturally-flavored proto-horror short stories. The Great God Pan—perhaps his most famous work—along with «The Inmost Light» and The White People deeply influenced later writers like H. P. Lovecraft. Stephen King has gone so far as to call The Great God Pan «maybe the best [horror story] in the English language». Besides his horror short stories, Machen also wrote a handful of post World War I supernatural shorts. One of these, «The Bowmen», was published in a popular newspaper and was implied to be non-fiction, leading to the creation of the «Angels of Mons» urban legend. This collection includes several other World War I short stories published by Machen.
As analogies go, that is a pretty good analogy of what I have done; you can understand now a little of what I felt as I stood here one evening; it was a summer evening, and the valley looked much as it does now; I stood here, and saw before me the unutterable, the unthinkable gulf that yawns profound between two worlds, the world of matter and the world of spirit; I saw the great empty deep stretch dim before me, and in that instant a bridge of light leapt from the earth to the unknown shore, and the abyss was spanned.
