In year 1178 A.D., as related by Clube and Napier in their book The Cosmic Serpent, a strange event was observed to affect the Moon, which may be explained by a large impact on the hidden face, originating the Giordano Bruno crater. A number of observations suggest that catastrophic cometary or meteoritic impacts around the same time also affected the Pacific basin: Maori legends of great fires destroying forests and the moa bird, to be associated to the recently found Tapanui craters; dynastic changes and migrations throughout Polynesia; very intense El Niño activity with flooding of the coastal Peruvian regions; demise of the local Moche civilizations, and the birth of the Incas civilization higher in the Andes; the emigration of the Aztects from the Pacific coast to the interior in the most well protected area from tsunams; unusually intense typhoon activity in the Chinese-Japanese see; unusually strong floods in Northern China with diversion of the course of the Huang Ho; unusually cold wheather in the Mongolian plateau, probably a main reason for the Mongolians invading nearby areas; a great sign in the sky seen by the boy Gengis Khan forecasting his future of world master; the number of comets seen in the sky as recorded by Chinese astronomers was unusually higher.


EMILIO SPEDICATO born in Milano, graduated in Physics and has been working since 1971 in numerical analysis (linear algebra and optimisation) and applied mathematics. His main work, with Abaffy and Broyden and several Chinese mathematicians, has been the development of the ABS algorithms, which unify the field of algorithms for solving linear algebraic equations and linearly constrained optimisation and provide novel and better methods than their classical counterparts (e.g. the implicit LX algorithm which is generally faster and more accurate and has less storage than the classical best algorithm, Gaussian elimination). Since 1979 he has been involved in the catastrophical reproach of homo sapiens history and related events in the Earth history. He has proposed that Hispaniola was the original location of Atlantis and is working on a project aiming to study mathematically the feasibility of a revised "polar model" approach to the history of the solar system (transition from a configuration with aligned planets in synchronous revolution around the Sun to the present configuration after capture of Jupiter at a time when homo sapiens already inhabited the Earth). He is professor of Operations Research at University of Bergamo.
