 After six months, "King Solomon's Mines" was published, and the book became the year's best seller, with printers struggling to print copies fast enough.In the process, "King Solomon's Mines" created a new genre known as the "Lost World", which would inspire Edgar Rice Burroughs' "The Land That Time Forgot", Arthur Conan Doyle's "The Lost World", Rudyard Kipling's "The Man Who Would Be King" 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", in which the influence of "King Solomon's Mines" is evident (Burroughs' Opar is supposedly the same the Biblical Ophir with which King Solomon traded).
