The Shapes

Les Xipéhuz (1888) is a novella by the writing duo J.-H. Rosny – although it is possible that Rosny aîné was the principal contributor. It describes the fight that threatens humanity, in the beginning of its history, against a non-organic form of intelligent life, the Xipéhuz, some sort of sentient crystals. It is both his first story set in prehistoric times, and his first science fiction story, although the term did not yet exist.
