John Taine (Eric Temple Bell, 1883-1960) was an accomplished mathematician and, as John Taine, a science fiction author. “White Lily” is a sci-fi horror story in which life based on crystalline silicate threatens to engulf carbon life on Earth. Humankind is about to be extinguished by rock crystals. The story was later rewritten as “The Crystal Horde” and published by Fantasy Press in 1952.
Groff Conklin, reviewing the 1952 edition, gave a mixed opinion; praising “one of the most magnificent science-horror ideas ever created,” but ridiculing the plot as “probably the worst yellow-menace-plus-Bolsheviks-plus-religious-prejudice mélange ever to hit science fiction.”
A good sci-fi horror film featuring a horde of life-threatening rock crystals is “Monolith Monsters” (1957). The crystals from outer space grow fast, grow to enormous height, and then fall over crushing everything in their path.
