The pictures found today in the zodiac were not developed by the Greeks, but were in place perhaps as early as 4000 B.C. predating even the civilizations of Sumeria . These pictures were not merely arranged in haphazard order to aid in the tracking of the star movements, but with the purpose of depicting an epic narrative. Authors like Bullinger and Seiss have suggested that there is a deeper meaning, one that goes beyond even the most illuminated of occult interpretations. The zodiac is a pictorial story of God's plan of salvation on earth. The key to understanding the celestial zodiac is found in ancient depictions of a mythical creature called a sphinx.
