The Great God Pan_ is the first book of the Welsh writer of weird tales and mystic Arthur Machen, published first in 1894. This book was regarded as a form of decadent literature and was panned by critics of the Victorian era. Arthur Machen was a fascinating character and antiquarian whose weird writings reveal his learning in the occult and his mystical inclinations. Machen was an Anglo-Catholic opposed to modernism in all its forms who was to join the secret society of the Golden Dawn, though he would reject the nefarious doings of such individuals as Aleister Crowley. Machen had an enormous influence on later writers of weird tales including especially H. P. Lovecraft.
