Nomicon

The Necronomicon is a fictional grimoire (textbook of magic) appearing in the stories by horror writer H. P. Lovecraft and his followers. It was first mentioned in Lovecraft's 1924 short story "The Hound", written in 1922, though its purported author, the "Mad Arab" Abdul Alhazred, had been quoted a year earlier in Lovecraft's "The Nameless City". Among other things, the work contains an account of the Old Ones, their history, and the means for summoning them.

Other authors such as August Derleth and Clark Ashton Smith also cited it in their works; Lovecraft approved, believing such common allusions built up "a background of evil verisimilitude." Many readers have believed it to be a real work, with booksellers and librarians receiving many requests for it; pranksters have listed it in rare book catalogues, and a student smuggled a card for it into the Yale University Library's card catalog.

Capitalizing on the notoriety of the fictional volume, real-life publishers have printed many books entitled Necronomicon since Lovecraft's death.

How Lovecraft conceived the name Necronomicon is not clear—Lovecraft said that the title came to him in a dream. Although some have suggested that Lovecraft was influenced primarily by Robert W. Chambers' collection of short stories The King in Yellow, which centers on a mysterious and disturbing play in book form, Lovecraft is not believed to have read that work until 1927.

Donald R. Burleson has argued that the idea for the book was derived from Nathaniel Hawthorne, though Lovecraft himself noted that "mouldy hidden manuscripts" were one of the stock features of Gothic literature.
