It is common knowledge thatThe problem is that constellations aren't actually groups of stars.
They just appear that way from our perspective.
Tropical astrology calculates with exact geometries of axes and orbits.
As a physicist I'm more fond of that.
What is cetrain is that fixed stars of a certain order of magnitude have an impact.
I tend to think that much more than sidereal constellations, the lunar Nakshatra's are relevant.
A difference in nuance, with a big difference in results.
at that ancient time when most people thought the universe was a living being
it was "The Norm" to imagine tiny points of light they saw in the night sky
as being grouped into separate, distinct sets of 'Images'.
These 'Images' were made up of separate stars which -
in the opinion of the ancient people of this planet
- seemed to be grouped together.
Thousands of years ago, on various parts of the planet Earth, different cultures
imaginatively 'connected the dots' of the tiny points of light
that they thought were close to each other
and personified them as 'Mythical Beings'
and narrated stories about the lives of these Mythical Beings.
The Mythical Beings and the stories of their lives varied
from culture to culture.
Different cultures imagined different images
in the patterns of the stars of the night sky.
The ancient people of this planet did not know
that these tiny points of light were hundreds
- perhaps even thousands - of light years distant from each other.
Former constellations are constellations that are no longer recognized
by the International Astronomical Union for various reasons
. Many of these constellations existed for long periods of time, even centuries in many cases
which means they still have a large historical value
and can be found on older star charts. http://en.wikipedia.org/wiki/Former_constellations
THE FOLLOWING ENCAPSULATED INFORMATION MAY BE FOUND AT http://www.physics.csbsju.edu/astro/asp/constellation.faq.html
The oldest description of the constellations as we know them
comes from a poem called Phaenomena
written by Greek poet Aratus 270 B.C.
and it is clear from the poem that the constellations mentioned
originated long before Aratus' time.
Some detective work reveals a plausible origin.
Firstly, Aratus' constellations excluded any near the south celestial pole
because that was always below the horizon of the ancient constellation-makers.
From the size of this uncharted area of the sky
we can determine that the people responsible
for the original constellations lived near a latitude of 36° north
which is south of Greece and north of Egypt
but similar to the latitude of the ancient Babylonians and Sumerians.
Because of a "wobble" of the Earth's axis of rotation
the position of the celestial poles changes slowly with time
- which is a phenomenon known as precession.
The constellation-free zone is not centered exactly on the south celestial pole
instead the uncharted area is centered on the place in the sky
where the south celestial pole would have been around the year 2000 B.C.
This date matches the time of the Babylonians and Sumerians.
So it seems likely that the Greek constellations
originated with the Sumerians and Babylonians.
From there, knowledge of the constellations somehow made its way to Egypt
- perhaps through the Minoans on Crete
who had contact with the Babylonians and settled in Egypt
after an explosive volcanic eruption destroyed their civilization,
and from there early Greek scholars first heard about the constellations
and wrote about them.
When most ancient cultures looked at the night sky they saw 'pictures' aka 'Images' in the stars.
The earliest known efforts to catalogue the stars date to cuneiform texts (i.e. Sumerian/Babylonian/Assyrian texts and artefacts)
and artefacts dating back roughly 6000 years.
These remnants, found in the valley of the Euphrates River,suggest
that the ancients observing the heavens saw the lion, the bull, and the scorpion in the stars.
