There is no precise beginning to the Age of Leo-- I would bet the scientists never mentioned it.

Scientists know that the post-Pleistocene megafauna went extinct over a relatively brief period of time. Not just megafauna, but birds, as well. There still isn't a conclusive answer as to why. Possibly there were separate but synergistic causes.

Yes, extra-terrestrial stuff hits the earth periodically, notably meteorites.

Waybread there is a precise date to the beginning of the Age of Leo as evidenced by the zodiac clock at Nabta Playa in the Sahara desert.

James Kennett and many other geologists and glaciologists now have a conclusive answer.

Vicki, I realize that I will never convince the True Believers, but the stone circle at the Nabta Playa of modern-day Egypt was not a "zodiac clock." https://en.wikipedia.org/wiki/Nabta_Playa It might well have been a calendar device based upon tracking movements in the heavens, but it had no known relationship to the zodiac. It probably dates to the 7th millennium BCE.

The zodiac itself is defined as a band of constellations through which the sun passes, and there is no evidence of its invention prior to the first millennium BCE in Babylon. The constellation Leo, as identified by Mesopotamians, probably does not pre-date 4000 BC. https://en.wikipedia.org/wiki/Leo_(constellation)

Astrological signs, as 30-degree sectors of the heavens, do not come into Babylonian astrology until ca. 500 BCE. Note that the zodiacal constellations are of dramatically different lengths along the ecliptic.

There certainly was no horoscopic astrology at these times. Horoscopic astrology emerges a few centuries later as a Hellenistic invention.

(See Nicholas Campion's Dawn of Astrology, Gavin White, Babylonian Star Lore.)

https://en.wikipedia.org/wiki/Astrological_age There is some evidence of ancient people being aware of the spring equinox constellations changing over time, but no understanding of precession. The idea of the astrological ages doesn't begin until Hellenistic times, probably beginning with Hipparchus.

If you can show me where James Kennett or any other serious Ph. D. geologist talks about the Age of Leo, I would love to see it. I suspect that people without scientific or archaeological credentials drew some kind of inference from his findings.

"The Origin Map" Discovery of a Prehistoric, Megalithic, Astrophysical Map and Sculpture of the Universe by Thomas G Brophy.

Reading this book is better than quoting unreliable Wikipedia.

I never suggested that James Kennett made any reference to the Age of Leo.

I am not a "true believer" (if you're suggesting that applies to me). I don't believe anything.

I leave this thread now. I have made my point.

Vicki, of course, you'll have to suit yourself. Brophy apparently has credentials as an astrophysicist, but not in archaeology. He is currently teaching at the California Institute for Human Science, which is an alternative campus billing itself as:

For almost two decades, CIHS has been conducting research on the healing applications of subtle energy by integrating science with spirituality. CIHS is grounded in the premise that human beings are composed of a biological, mental and spiritual dimension. The Institute?s main goal is to provide an education that integrates the three dimensions of the human being. The major aim of our academic programs is to study the body, mind, and spirit as an integrated whole.

Which is fine, but it doesn't sound objective. I couldn't find that it was accredited by the WASC http://www.acswasc.org/

Brophy's book apparently couldn't pass an academic peer review. Had you not decided to leave the site, I would have been willing to track down the more recent work by the University of Colorado scientists.

I'm not saying that Brophy is or is not correct. But my hope is that as astrologers, we become more discerning critical thinkers, because there is so much woo-woo stuff out there.

I thought this news item might be of interest in the context of this thread:
