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.
Pan (god)
Many modern scholars consider Pan to be derived from the reconstructed Proto-Indo-European god "*Péhusōn", whom these scholars believe to have been an important pastoral deity ("*Péhusōn" shares an origin with the modern English word "pasture"). The Rigvedic god Pushan is believed to be a cognate of Pan. The connection between Pan and Pushan was first identified in 1924 by the German scholar Hermann Collitz. According to Edwin L. Brown, the name "Pan" is probably a cognate with the Greek word ὀπάων "companion".
