Carter throughout Time and Space come from Price, who was well read in neoplatonic thought, theosophy and the occult. Even the quote from the Necronomicon is mainly by Price in outline though put in more Lovecraftian language. The sub-plot about Yaddith was entirely Lovecraft's idea however. Hoffman Price's tales were oriental, and 'Umr at-Tawil was merely an Arab who had preternaturally long life in his draft. In any case, Price was pleased with the result, writing that Lovecraft "was right of course in discarding all but the basic outline. I could only marvel that he had made so much of my inadequate and bungling start." The story appeared under both authors' bylines in the July 1934 issue of Weird Tales; Price's draft was published as "The Lord of Illusion" in Crypt of Cthulhu No. 10 in 1982. Edward Guimont has proposed that an influence was Jack London's 1915 novel The Star Rover, which Lovecraft owned. Reception Lovecraft scholar Will Murray says of "Through the Gates of the Silver Key", "As a Dunsanian fantasy, the Price/Lovecraft collaboration is a failure; as a Mythos story, it is rich with ideas, but curiously diluted." In A Thousand Plateaus (1980), Gilles Deleuze and Félix Guattari called the story one of Lovecraft's masterpieces. References Sources Robert M. Price, editor, Black Forbidden Things.
