Re: Equinoxes

I believe it was Hipparchus, one of the great Greek thinkers. He noticed a
shift in the position of stars after comparing much earlier star charts
made by ancient Persians or Mesopotamians. He charted about two thousand
stars. It is such an amazing discovery that I like to call him Hip
Hipparchus!

I wonder if anyone can help with the following questions?

When was precession of the equinoxes first observed and how was the
observation made? When was it verified?

It seems from my reading that is has been known for a very long time and
yet I wonder how something with such a large period was observed
originally.

Thanks for your help. Dave Abineri
