I recently came across this paper in academia.edu that Russ von Ohlhausen wrote a few years ago. It explains the precession of the ages in astrological terms and its relationship to the symbols and myths within the 2,160 year period it takes to move from one sign to another. The main example here is Jesus within the age of Pisces which many believe is the process of ending while the newer age of Aquarius is already upon us.
I would argue that the symbols presented in the Oracle story are reflective of this change. Aquarius is an air sign where we've established that we have UFOs in the air, images in the landscape seen directly from satellites in the air, our own "arrival" into the scene via computers showing the images etc. Also there is an emphasis on psychology (the mind) vs. the emotions of Pisces.
My sense is that the End of Days thinking is tied up with the concept of linear time - when the age ends, while cyclical time continues to turn endlessly.
