ネクロノミコン
[i]That which shall not be read...[/i]

The [b]Necronomicon[/b] is a fictional grimoire appearing in the stories by horror writer [[h_p_lovecraft|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 [[elder_thing|Old Ones]], their history, and the means for summoning them. As such, it is considered a dangerous artifact that can be used as a gate to enable powerful beings from alternate lost dimensions of [[space]] to enter our world.

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 even 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.
