Ragnarok: The Age of Fire and Gravel by Ignatius Donnelly.Hardcover, English text, 1970. Good condition. Dust jacket worn. Rare, hard to find first edition.Comet, end of the world, disasters, catastrophe."Ragnarok: The Age of Fire and Gravel," by Ignatius Donnelly, proposes a catastrophic theory about the end of the last ice age, suggesting a comet impact caused widespread destruction and the end of a technologically advanced civilization. Donnelly argues this event, rather than gradual processes, led to massive fires, floods, and harsh winters, forcing humanity to retreat to caves and lose much of their knowledge. He connects this theory to ancient myths of global floods and fires, suggesting they are remnants of this cataclysmic event. Donnelly theorizes that a large comet struck the Earth around 12,000 years ago, causing significant geological changes and widespread destruction. He argues this impact wiped out a technologically advanced civilization.商品の情報カテゴリー:本・雑誌・漫画>>>本>>>洋書商品の状態: 目立った傷や汚れなし","subname":"細かな使用感・傷・汚れはあるが、目立たない
