You stated that there was much confusion about applying the twelve tribes of Israel to the Zodiac. Well, of course there would be great confusion because the Zodiac does not describe israel. The lines below from the Enuma Elish show that the beginnings of the Zodiac rests in Babylon and probably ancient Sumer or even earlier.
THE FIFTH TABLET
"He (Marduk) made the stations for the great gods;
The stars, their images, as the stars of the Zodiac, he fixed.
He ordained the year and into sections he divided it;
For the twelve months he fixed three stars.
After he had ... the days of the year ... images,
He founded the station of Nibir [the planet Jupiter] to determine their bounds;
That none might err or go astray,
He set the station of Bel and Ea along with him.
He opened great gates on both sides,
He made strong the bolt on the left and on the right.
In the midst thereof he fixed the zenith;
The Moon-god he caused to shine forth, the night he entrusted to him.
He appointed him, a being of the night, to determine the days;
Every month without ceasing with the crown he covered him, saying:
"At the beginning of the month, when thou shinest upon the land,
Thou commandest the horns to determine six days,
And on the seventh day to divide the crown.
On the fourteenth day thou shalt stand opposite, the half....
When the Sun-god on the foundation of heaven...thee,
The ... thou shalt cause to ..., and thou shalt make his...
... unto the path of the Sun-god shalt thou cause to draw nigh,
And on the ... day thou shalt stand opposite, and the Sun-god shall...
... to traverse her way."
