Hare "Ragnarok: The Age of Fire and Gravel" by Ignatius Donnelly is a book published in 1883. Donnelly proposes that a massive comet struck Earth 12,000 years ago, destroying an advanced civilization and plunging survivors into a dark age. He supports his theory with geological evidence from the Great Lakes, chemically altered rocks, and ancient myths from cultures worldwide describing cosmic catastrophe, fire, floods, and prolonged darkness.
