Rivkah, John Hogue may be an astute scholar of Nostrodamus, but he is not the finest mundane astrologer out there. He is just one who promotes more, and writes more books. His sources for the translations of aramaic, or any references to Torah or Zohar are incredibly off, incorrect, and skewed by enough bias to question his sources' motivations.
Look for astrological works by Nancy Sommers. Her work has been far more accurate, and she is not biased. She is far more respected by the Astrological community because she does not make money by "shock value". Her work times precisely with Ezekiel, Joel, Obidiah, Zechariah, Daniel,and the Zohar. She is a far better mundane (political-event) astrologer.`
Nostrodamus is only one source. But as you know, he did not give dates or define things clearly. He was afraid of the church at that time, and being persecuted. Therefore he intentionally kept his writings obscure.
In professional astrology, riddles are not acceptable delineation. Mathematical precision, proven event timing, is. Read Nancy Sommers astrology blog. Then compare it to the writings of the ancient Jewish Prophets- the accuracy will amaze you, and you will get a far better understanding of what is happening.
For the most reliable, scholarly accurate, rabbinic translations of the ancient GogUmogog Prophecies- go to gogumogog.com/html/prophetic_texts.html
I hope this helps.
