Relations to seasons

I don't know if you've read this or not, but its so coincidental. Astrology makes life seem so ordered. Anywho~ I don't remember what site this was from, but it seemed like a really good description of the qualities. Ya know, fixed, mutable, cardinal.

But, basically it talks about Spring, Summer, Fall and Winter.
Aries is cardinal, and initiates the start of spring.
Taurus is fixed, and keeps the season going.
Gemini is mutable, and prepares for summer.
Cancer is cardinal, and initiates the start of summer.
Leo is fixed, and maintains the height of summer.
Virgo is mutable, and handles the change into fall.
Libra is cardinal, and starts of the fall season.
Scorpio is fixed, and keeps the fall season in swing.
Sagittarius is mutable, and readies itself for the change into winter.
Capricorn is cardinal, and leads the way into winter.
Aquarius is fixed, and continues the season of winter.
Pisces is mutable, and readies itself for the blossoming spring again.

Now isn't that just all so convenient.
There must be so much more you could look into this, but its like absolutely everything is involved with the evolution of astrology.

Do you think astrology evolved? Or that it was immediately taken into effect from the time the solar system spawned?
