Hi.
 
I read the article “Astronomical Discovery in Revelation” recently.  I had known for years that the woman described in Rev. 12 was the constellation Virgo.  In fact what is described in Rev. 12 with the woman clothed with the sun and the moon at her feet happened on the night that Jesus was born, September 11th, 3 B.C.  You can see it on a good star map.  >From about 6 to 7 p.m. approximately the sun was setting and it went through her body since she was lying on the horizon, and there was a new moon below her feet.  Of course, this appears every year, but you can pinpoint the year by other events described in the bible and other star and constellation conjugations.
 
As I was reading my bible last night, I realized that the dragon described in Rev. 12 must also represent the constellation Draco.  So I got on the computer hoping to find a star map to see where Draco is in relation to Virgo.  I was very surprised to find out it’s right next to it.  I found this article, and read about the crowns, and what the 17s stand for in Rev 13.  Very interesting!  Also, because of the size of the constellation, it does take up one third of the sky.  I am sure you are right and that it is all speaking of constellations and measurements in the sky.  According to Psalm 19 God wrote the redemption story in the stars before it was ever written on paper.  There is an excellent book on this subject by an 18th century author who did extensive study on the word of God.  His name is E.W. Bullinger and the book is “The Witness of the Stars.”
