地獄の門
The book inspired parodies and knock-offs, including a reissue of George Wood's 1858 "Future Life" renamed as "The Gates Wide Open". Mark Twain later stated that his short story "Captain Stormfield's Visit to Heaven" was a satire of "The Gates Ajar". In 1894 "The Gates of Hell Ajar" appeared, written by Connecticut author John Bolles.
