 As has been intimated above, Lovecraft adopted some of Machen's techniques and terminology for use in his Cthulhu Mythos stories.The story has also served as the inspiration for T. E. D. Klein's novel "The Ceremonies" and may have been an influence on the plot of Guillermo del Toro's film "Pan's Labyrinth".Ursula Vernon's 2019 novel,"The Twisted Ones," is also a contemporary take on the story.
