Kerry....You might find better sources than me using a google search. Sadly so much is biased toward Christian tradition. The Jewish Encyclopedia, TheTorah.com and Wiki are always good places to start.
Jeffro, I understand what you are saying but when the full text doesn't fit 70CE very well, it's reasonable to consider alternatives. While I have agued that 'earthquakes' might just be standard apocalyptic motif, (e.g. Rev 6:12-14), if we are now assuming there was a physical earthquake, or series of them, that would have impressed the writer and readers, our best period is later. I haven't been able to locate any recorded (of course minor ones may not have been) earthquakes around 70. (Unless we count the two fictional ones slipped in Matthew)
There were a series of major ones from 98-132CE that everyone would have heard of.
And as I said, the empire wide wars during the second Jewish revolt would have been of incredible interest to the Judeo-Christian world. This is the kind of significant notoriety I would expect if we were assuming a literal meaning to these 'signs'. It's also worth considering whether what was originally boilerplate apocalypse language was understood literally by the next generation.
Also, the reference to preaching in 'all the nations' and the State sponsored oppression of Christians certainly better fits the period of Trajan and later. It's estimated there were only a few thousand Christians in the world by 70CE and they were centered in a few locations.
The oddest element that always disturbed me, which I mentioned before, is how, seeing the conquering Roman standards on the Temple mount could represent an opportunity to escape. It was far too late to escape. That's why the Lukan version is either an earlier form (70-130's) or the author saw the logical defect in Mark and Matt's timeline and changed 'abomination in the holy place' it to 'surrounding armies'. I'm inclined to favor Luke preserves an earlier form as we have other examples of Luke not including wording from Matt that otherwise are suspected later additions. (e.g. Matt 24:12) The Markan and Mattean language makes far more sense in the time of Hadrian. It was that act that triggered the war, hence depicting it after the fact as an opportunity to escape make sense.
It's then a possible solution for these details. Again, the parallels of the events surrounding Bar Kokhba and Judas Maccabeus, are pretty hard to miss. It would not be at all surprising if they inspired some refinements to the text.
It's all irrelevant to many, but it's an interesting puzzle for some.
