In chapter 9, the 5th angel sounds, and a star fell from heaven unto the earth (Polaris time is dated as 2,100 A.D.); and to him was given the key (date) of the bottomless pit of the measurement of time on the 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 ('L'-'o'-see-us-'t's) upon the earth. They had power as scorpions of the earth have power. They would hurt men without the seal of GOD. They had a King over them, which is the angel of the bottomless pit (of time), whose name in Hebrew is Abaddon ('a'-'b'-add-on) but in Greek Apollyon ('a'-many-on). Those who understand these things will bring others to enlightenment but many will be left in the dark for their lack of study on the things of God.
Then the 6th angel sounds; and there are loosed the 4 angels (or angles of 90 degrees each), which are bound in the Great river Euphrates. They were loosed to slay (possibly by the double-edged S-word 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 (horse quadrants of 'a', 'b', 'c' and 'd) had breastplates of fire, and of Jacinth, and Brimstone. The heads of the horses were as Lions, and out of the mouths of them that sat on them 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 could be referring to the constellations of 'Draco' and 'The Little Dipper', which have heads and tails. The pole star 'Thuban' is situated in the tail of 'Draco' and 'Eltanin' is at its head. The pole star 'Polaris' is in the tail of 'The Little Dipper' and 'Kochab' is in its head. If the time period is wrong for these pole stars at their apexes or peaks (closest points to the 'Precessional Circle') then this could cause hurt by throwing off all the other dates. The people who, at that time, have the knowledge of the time periods of these 'pole stars' will possess the Power of God over the nations because they will know more approximately when the times and colors occur around the 'Great Circle Clock'! Remember also that the times can all be thrown off when there are flucuations in the movements of the earth's axis caused by earthquakes and other disturbances.
