Derek S. Allan(1917-) & J. Bernard Delair(1932-) are two British scientists who authored Cataclysm: Compelling Evidence of a Catastrophic World Change, 9,500 BC, which discusses a global catastrophe that affected the planet during the 10th millennium BC. They have built upon and refined the catastrophist theories of Velikovsky. Drawing on the details of worldwide myths and recent scientific research they have developed a plausible argument for believing that the Earth was violently impacted upon by an extraterrestrial event over eleven thousand years ago. Their contention is that ejecta, of varying sizes, from a supernova in the nearby Vela constellation, entered our solar system resulting in devastation on a planetary scale. The Earth did not escape and the destruction visited on our world is the sobering subject of this book. In 1977, George Michanowsky also referred to the Vela supernova but dated it to 4000 BC and considered its effects to be more visual than physical. Neither Michanowsky nor his book were referred to by Allan & Delair.
The authors boldly challenge accepted Ice Age theory, denying that the usual evidence of glacial damage is correct, as such striations are found in areas that did not have to endure an ice age! This book will no doubt require revision, as our understanding of the past develops, but for the present it offers an insight into the incredible disasters that could have wiped out our ancestors. Delair wryly commented that evolution may not be just the survival of the fittest but also the survival of the luckiest.
Allan & Delair have used scientific evidence to indicate that 9500 BC was the approximate date for their proposed cataclysm. Commenting on the destruction of Atlantis they state that “we found Plato’s account of the loss of the legendary continent of Atlantis (the empire of Atlas) to be one recollection of the occurrence of radical worldwide topographical changes some 11,500 years ago initiated by powerful and violent celestial agents” [014.225]. The coincidence of this date with the date apparently related to Solon, has been seized upon by the more fundamentalist Atlantologists, who insist that Plato’s early date for the destruction of Atlantis is, euphemistically speaking, written in stone.
The authors range over the entire spectrum of catastrophist elements, such as the Deluge, extraterrestrial encounters, bone caves, frozen mammoths and pole shift. Inevitably, they were forced to engage in some speculation, but, if nothing else, this valuable work throws some light on a dark and terrifying period in our planet’s history.
Maurice A. Williams, who has written on a number of scientific and religious subjects has offered a very positive review(a) of Cataclysm describing it as a ‘must-read’ book. While I concur, I would urge caution.
