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.
Piccadilly
In Arthur Machen's 1894 novella "The Great God Pan", Helen Vaughan, the satanic villainess and offspring of Pan, lives off Piccadilly in the pseudonymous Ashley Street. Margery Allingham's fictional detective Albert Campion has a flat at 17A Bottle Street, Piccadilly, over a police station, although Bottle Street is equally fictitious.
