Necronomicon - The secret book

The much quoted occult fictionist H P Lovecraft mentions an obscure text called Necronomicon in his works. The Necronomicon is a book which is purported to contain secret formulas to summon The Old Ones. Nekros in Greek means dead, nomos is the law and eikon is the image, so necronomicon could mean `An image of the law of the dead.' Though Lovecraft maintained that the Necronomicon did not exist in reality but stories about the existence of the book abound. In fact some publishers have produced their versions of the Necronomicon consequently. The image of the book (from Wikipedia) is of the Necronomicon used as a stage prop.
