Nyarlathotep is a fictional character created by H. P. Lovecraft. The character is a malign deity in the Lovecraft Mythos, a shared universe. First appearing in Lovecraft's 1920 prose poem "Nyarlathotep", he was later mentioned in other works by Lovecraft and by other writers. Later writers describe him as one of the Outer Gods, a malevolent pantheon.In a 1921 letter to Reinhardt Kleiner, Lovecraft related the dream he had had—described as "the most realistic and horrible [nightmare] I have experienced since the age of ten"—that served as the basis for his prose poem "Nyarlathotep". In the dream, he received a letter from his friend Samuel Loveman that read:Don't fail to see Nyarlathotep if he comes to Providence. He is horrible—horrible beyond anything you can imagine—but wonderful. He haunts one for hours afterwards. I am still shuddering at what he showed.Lovecraft commented:I had never heard the name NYARLATHOTEP before, but seemed to understand the allusion. Nyarlathotep was a kind of itinerant showman or lecturer who held forth in public halls and aroused widespread fear and discussion with his exhibitions. These exhibitions consisted of two parts—first, a horrible—possibly prophetic—cinema reel; and later some extraordinary experiments with scientific and electrical apparatus. As I received the letter, I seemed to recall that Nyarlathotep was already in Providence.... I seemed to remember that persons had whispered to me in awe of his horrors, and warned me not to go near him. But Loveman's dream letter decided me.... As I left the house I saw throngs of men plodding through the night, all whispering affrightedly and bound in one direction. I fell in with them, afraid yet eager to see and hear the great, the obscure, the unutterable Nyarlathotep.Will Murray has speculated that this dream image of Nyarlathotep may have been inspired by the inventor Nikola Tesla, whose well-attended lectures did involve extraordinary experiments with electrical apparatus and whom some saw as a sinister figure.
