Plato states that the Egyptians told Solon that the destruction of Atlantis occurred 9000 years before that date, to wit, about 9600 years before the Christian era. This looks like an extraordinarily long period of time, but it must be remembered that geologists claim that the remains of man found in the caves of Europe date back 500,000 years; and the fossil Calaveras skull was found deep under the base of Table Mountain, California, the whole mountain having been formed since the man to whom it belonged lived and died. "M. Oppert read an essay at the Brussels Congress to show, from the astronomical observations of the Egyptians and Assyrians, that 11,542 years before our era man existed on the earth at such a stage of civilization as to be able to take note of astronomical phenomena, and to calculate with considerable accuracy the length of the year. The Egyptians, says he, calculated by cycles of 1460 years--zodiacal cycles, as they were called. Their year consisted of 365 days, which caused them to lose one day in every four solar years, and, consequently, they would attain their original starting-point again only after 1460 years (365 x 4). Therefore, the zodiacal cycle ending in the year 139 of our era commenced in the year 1322 B.C. On the other hand, the Assyrian cycle was 1805 years, or 22,325 lunations. An Assyrian cycle began 712 B.C. The Chaldeans state that between the Deluge and their first historic dynasty there was a period of 39,180 years. Now, what means, this number? It stands for 12 Egyptian zodiacal cycles plus 12 Assyrian lunar cycles. +--------------------+----------+ | 12 X 1460 = 17,520 | | +--------------------+----------+ | | = 39,180 | +--------------------+----------+ | 12 X 1805 = 21,660 | | +--------------------+----------+ "These two modes of calculating time are in agreement with each other, and were known simultaneously to one people, the Chaldeans. Let us now build up the series of both cycles, starting from our era, and the result will be as follows:
