OK you lot, hold on there a rootin tootin minute!
Nostradamus was a clever old sausage, he made his predictions based on the past. What he did was, he looked at major events in his past and worked out the alignment of the planets at the time the events happened. With me so far?
Ok, so having got a planetary alignment, he then looked at the next time this particular configuration of stars would occur and he then wrote a nifty little verse which implied what the original historical event was, but vague enough that it could relate to just about anything.
Sometimes the planetary alignment happened more than once, and he just wrote another little verse. Easy see :)
So, the thing is.. do you believe that the stars can predict the future? My feeling is that you will get some events that you can wriggle around into fitting with something that happened recently, like the 2nd world war for example. But coincidence has to play a major part in any of Nostradamus’ precitions wouldn’t you think?
