I learned the constellations by observing the night sky and used a field manual to do so.
The same skills used by our forbearers are required.
I wonder what the cave dwellers of Lascaux used for a field manual.
The point is more than simply recognizing the constellations along the zodiac. It's the science behind using them to recognize that the zodiac moves along the ecliptic.
Think about it. People existing in caves 40 000 years ago noticed that the stars move along the ecliptic one degree every 72 years (according to the experts).
So, in a lifetime of hunting, gathering and whatever, this almost imperceptible movement was so evident and important that it warranted being recorded on cave walls.
How and why?
