Chapter 9
In chapter 9, the 5th angel/star sounds ('Thuban' of 'Sardis') and a star fell from heaven unto the earth and to him was given the key of the bottomless pit. As the time is made known to when 'Thuban' reached it's closest point to the 'Precession Circle', we are now able to calculate the other time periods more accurately around this 'Great Clock'. The bottomless pit (of time) is opened and there arises a smoke out of the pit; and the sun and air were darkened by reason of the smoke of the pit. There came out of the smoke locusts upon the earth. They had power as scorpions of the earth have power. They would hurt men without the seal of GOD in their foreheads for 5 months (this could be 5/12 of the 'Circle' or @10,800 years). They had a King over them, which is the angel of the bottomless pit, whose name in Hebrew is Abaddon ('a'-'b'-add-on) but in Greek Apollyon ('a'-many-on).
Then the 6th angel/star sounds and there are loosed the 4 angels which are bound in the Great river Euphrates. (These are possibly the four stars that make up the dipper of the 'Little Dipper' constellation). They were loosed to slay (possibly by the double-edged Sword of Jesus' mouth) the 1/3 part of men. The number of the army of horsemen were 200,000,000. Them that sat on the horses (quadrants 'c' and 'd') had breastplates of fire (of stars), and of Jacinth, and Brimstone. The heads of the horses were as Lions (as of the 1st Beast Quadrant), and out of the mouths of them (the stars) that sat on them (the quadrant horses) issued fire and smoke and Brimstone. I believe the stones around the Brim are Pole Stars around the 'Precessionary Circle of the Equinoxes'. The power was in the mouths and tails. Their tails were like unto serpents, and had heads, and with them do they hurt. Maybe this is referring to the 'Little Dipper' constellation and its Pole Stars (having 'Kochab' in the head and 'Polaris' in the tail).
