The Dream-Quest of Unknown Kadath
"The Great God Pan" was highly influential on the circle of writers around H. P. Lovecraft. The structure of Machen's story influenced the structure of Lovecraft's "The Call of Cthulhu" (1928). "Pan"s depiction of a monstrous half-human hybrid inspired the plot of Lovecraft’s "The Dunwich Horror" (1929), which refers to Machen’s novella by name. According to Lovecraft scholar Robert M. Price, "The Dunwich Horror' is in every sense an homage to Machen and even a pastiche. There is little in Lovecraft's wonderful story that does not come directly out of Machen's fiction." "Pan" also inspired Lovecraft to create his character Nodens who appears most prominently in "The Dream-Quest of Unknown Kadath" (1943).
