As a result of the success of the film "Rosemary's Baby" and the concomitant growth of interest in Satanism, an editor at Avon Books, Peter Mayer, approached LaVey and commissioned him to write a book, which became "The Satanic Bible". While part of the text was LaVey's original writing, other sections of the book consisted of direct quotations from Arthur Desmond's right-wing tract "Might is Right" and the occultist Aleister Crowley's version of John Dee's "Enochian Keys". There is evidence that LaVey was inspired by the writings of the American philosopher Ayn Rand; and while accusations that he plagiarized her work in "The Satanic Bible" have been denied by one author, Chris Mathews stated that "LaVey stole selectively and edited lightly" and that his "Satanism at times closely parallels Ayn Rand's Objectivist philosophy." The book "The Satanic Bible" served to present LaVey's ideas to a far wider audience than they had previously had. In 1972, he published a sequel, "The Satanic Rituals".
