Precession: The Great Year

As humans on Earth there are two celestial motions that affect us most obviously. Earths diurnal motion, its rotation on its axis responsible for day and night, and Earth’s revolution around the sun, determining our yearly cycles (winter, spring, blooming, hibernation, migration). A third and less obvious celestial motion is precession. Its time scale hides the immediate impact of precession, as the human being has a life span of one-360th of a roughly 24,000-year precession cycle.

In the book Hamlet’s Mill, Giorgio de Santilla, former professor of the history of science at MIT, and coauthor Dr. Hertha von Dechend, explain how ancient cultures viewed consciousness and history as a cyclical cycle. In contrast to our linear model of time, these cultures believed in a vast cycle of time that consists of the rising and falling of ages, and moves with the precession of the equinox. Santilla and Dechend show that more than thirty ancient cultures believed in this cycle that Plato called The Great Year.

In the hyperlink above, you can read about the thinking behind these precessional cycles and how a moving Solar System might provide a logical reason for The Great Year and alternating ages.
