I am led to believe however that most if not all the old testament is symbolism for ancient Astrology. It is known that some old AE's tombs from 2100bc have Decanates Astrology charts on them. Decanates astrology involves 48 constellations in the sky, the 12 major ones and 36 minor ones. I'll list a few for you, see how many you can recognize in the bible.
Aries the Ram - sheep and ram used for sacrifices
Pisces the Fishes - Sign of Christianity
Serpens the Serpent - Talking serpent of the Adam and Eve story
Argo Navis the Great Ship - Noahs Ark
Gemini the twins - Cain and Abel
Orion the Hunter - Ancient Egypt
Triangulum the Triangle - Pyramids
It takes the sun 25,920 years to go through each house of the major constellations. It's called the Great Cycle. Around 23908bc we entered Aquarius and around 2012 we Re- Enter Aquarius thus completeing a cycle, the Beginning and The End, The alpha and the omega.
Hope this helps,
