I was studying the first half of the Book of Revelation, knowing that most Christians take the prophecies in chapters 6 to 9 to refer to the End of the Age. It seems to me that the Book of Revelation is much more chronologically ordered than many people might think. Chapter 11 starts in 688 A.D., as we know, with the Abomination of Desolation (Dome of the Rock) constructed in the outer courtyard of the former temple of Solomon, which area was given to the Gentiles (Muslims) for forty-two months (i.e. until 1967, using the principle of "days" = years). It seems to me that the content of the earlier chapters (including chapters 6 to 9) refers to things that happened prior to 688 A.D. The events prophesied in chapters 6 to 9, thinking particularly of the cosmic disturbances (in Revelation 6:12-16) and the disasters associated with the first five trumpets (Revelation 8:7 to 9:12) up to the end of the "first woe", all seemed to me to be fairly contemporaneous. The associated timescale is quoted as "five months" in Revelation 9:5. Since "five months" would be 152 days (using the Julian calendar), this timespan would represent 152 years. If the 152 years end in 688 A.D., which is where we have reached by the beginning of chapter 11, then the 152 years must start in 536 A.D. The date of 536 A.D. meant nothing to me, so I did a "Google" search for 536 A.D., and others may wish to try this. It seems that 536 A.D. was an exceptionally calamitous time for those on planet Earth. There are historical records that speak of eighteen months of darkness, famine, disease and death. In other words, the catastrophic events of Revelation 6:12-16 and Revelation 8:7 to 9:12 really happened in 536 A.D. An article in 'New Scientist' attributed these catastrophic events to multiple comet impacts and a resulting 'dust cloud' that filled the atmosphere. I invite others to check this. Revelation 9:13-19 then describes the rise of Islam after the effects of the catastrophe of 536 A.D. were beginning to wear off. The catastrophe of 536 A.D., in which (according to John) one third of everything was afflicted, gives us some insight regarding what will happen at the very end of the Age when everything will be afflicted - see the 'Bowl Judgments' of Revelation 16. Whether the events of Revelation 16 will be caused by an even greater cometary impact is a matter of speculation, but I am watching! Does anyone else have similar thoughts on Revelation chapters 6 to 9?
