A balloon ascent to the Heavens... A man with X-ray vision... A utopian metal city built on giant pylons above Paris... A sexless world in which women reproduce parthenogenetically and man is unknown... Is science insane? Unholy? See nine French authors of the 19th century grapple in a ground-breaking fashion with the future themes of science fiction. All the stories included in this volume predate the first translation into French of H.G. Wells. They are representative of a distinct tradition of romans scientifiques whose cardinal influences included astronomer Camille Flammarion and Villiers de l'Isle-Adam. This edition includes a historical introduction and notes by sf scholar Brian Stableford.
