Sussex Manuscript
From Multiversal Omnipedia
The Sussex Manuscript, also known as Cultus Maleficarum, was an English translation of the Latin Necronomicon, made by Baron Frederic of Sussex in England. It was published in 1598. The Manuscript's translated text bears little resemblance to any other version of the Necronomicon.
Comments
The Sussex Manuscript was an actual attempt at a "real" Necronomicon made by Lovecraft fan Fred Pelton.
