Two British astronomers, Victor Clube and Bill Napier, wrote an intriguing work entitled "The Cosmic Serpent," which addressed the origins of the comets, historical impacts, and mythology equals history of comets. With roughly 280 pages and eleven chapters (including Epilogue), this book is quite a fascinating read.
The first part of the book deals with an interesting perspective of our galaxy involvement in the cosmic processes and how other stars can possibly deflect or "knock" the comets in the direction of the Sun, as well a look at the question of where the comets come from. Then, the authors go on to discuss the question of impacts and the role of cometary bombardment in mass extinctions and the Earth changes, including that of the ice ages.
The last part of the book, which intrigued me, focuses on the examination of ancient history, archeology, and mythology where the comets were seen. The authors then pointed out that the comets were originally the principal mythological sky gods, such as Zeus of the Greek mythology and Osiris of the Egyptian mythology. And, because they were "gods," they tend to be dismissed and become "meaningless" in the eyes of the modern scientific community. Chapter Nine of this book focuses on the battle of Zeus and Typhon, which may have taken place in 1369 BC (which is further discussed in tenth chapter), and the question of clues in the myths as cosmic connections. The authors made strong point that the comets were seen number of times in our prehistoric skies and they were depicted in our mythology as well in the biblical accounts.
They also mentioned that the scientific community had overlooked the seriousness of so-called short-period comets in our past and dismissed the possibility of comets in disguise of mythological sky gods. It is not just the mythologies that can be an evidence for the cometary events, but it is the physical evidence of catastrophic events in the past, including the Tunguska event and the craters on the Moon, Mars, and Earth.
Personally, I found this work to be of importance for many whom needs to be aware of the cometary threats, especially in our near future. Both "The Cosmic Serpent" and The Cosmic Winter are important works by Clube and Napier, yet not easily available, and they should be published once more for the public. I would strongly recommend these books.
