In the process, King Solomon's Mines created a new genre known as the "Lost World", which inspired Edgar Rice Burroughs' The Land That Time Forgot, Arthur Conan Doyle's The Lost World, Rudyard Kipling's The Man Who Would Be KingRobert E. Morsberger, "Afterword" in King Solomon's Mines Reader's Digest edition 1994. and H. P. Lovecraft's At the Mountains of Madness. In The Return of Tarzan (1913), Edgar Rice Burroughs introduced his own lost city of Opar (supposedly the same as the Biblical Ophir with which King Solomon traded), in which the influence of King Solomon's Mines is evident. Opar reappeared in further Tarzan novels and was later taken up in the Khokarsa novels of Philip José Farmer and various derivative works in other media. Burroughs also introduced other lost cities in various hidden corners of Africa for Tarzan to visit, such as a valley in Tarzan, Lord of the Jungle inhabited by stray Crusaders still maintaining a Medieval way of life. Robert E. Howard's Conan the Barbarian also visited several lost cities, and Lee Falk's The Phantom was initially written in this genre. A much later Lost World novel is Michael Crichton's Congo, which is set in the 1970s and features characters seeking a trove of diamonds in the lost city of Zinj for use in electronic components rather than jewellery. The last sentence in Congo reads: “The projected intersection point now marked a field of black quatermain lava with an average depth of eight hundred meters—nearly half a mile-over the Lost City of Zinj.” The name “Quatermain” is sufficiently close to the geological term “Quaternary” that some readers, to be sure, would have missed the homage.
