Le Dernier Homme
Jean-Baptiste Cousin de Grainville
 The story is told by a spirit to a young man who comes upon its cave while traveling in Syria. The protagonist, Omegarus, is the son of the King of Europe and the last child born there in a far future in which the earth is becoming sterile and the human ability to reproduce is fading. He sees a vision of Syderia, the last fertile woman. She lives in Brazil, so he travels there in an airship. After various adventures there, including meeting Ormus, the Spirit of Earth, who urges them to begin a rebirth of the human race, the pair return to Europe. There they meet Adam, the first man, who has been condemned by God to watch all the damned among his descendants enter Hell, and who is now charged with persuading Omegarus and Syderia not to prolong the life of humanity, which God has determined must now end. He succeeds in having Omegarus leave Syderia, who then dies. Ormus, who cannot survive without humanity, despairs, and the world begins to end and the graves of all the dead to open.
