Jeffro : ... the method doesn’t establish the date of Jerusalem’s destruction. But I have also already pointed out that the method disproves Watch Tower Society chronology for earlier events in the Iron Age.
Fisherman : What results does the magnetic dating method yield using 607 instead of 586? How does it falsify 607?
It would be well worth reading the article before asserting that the method disproves Watch Tower Society chronology. It does not. It negates or supports hypotheses of contemporaneity. For example,
The intensity results from Tel Malhata are slightly lower than those recorded in Lachish II [which was destroyed at the same time as Jerusalem]. This supports the hypothesis that in 586 BCE the Babylonian army was focused on Jerusalem and had no interest in going far south to the area of Malhata. It seems that after 586 BCE, when the Kingdom of Judah ceased to exist, the eastern and southern periphery of the kingdom collapsed, probably in a gradual process, and sites were destroyed, perhaps by the Edomites or other nomadic elements.
In the above quotation, reference to 586 BCE is based on the presumption that the destruction of Jerusalem happened on that date. But what if Jerusalem was destroyed in 607 BCE?
The geomagnetic field data have nothing to say about that. All it tells us is whether other cities that were burned down in military campaigns had the same geomagnetic field data (which suggests it occurred during the same military campaign). It could also suggest whether other Babylonian campaigns were earlier or later based on a probability distribution of ages. So, if Jerusalem (and Lachish) was destroyed in 607 BCE then the probability distribution curve for the Babylonian military campaigns would be shifted by 20 years.
What about the other evidence which cause the vast majority of researchers to accept 586 BCE? That has been discussed endlessly elsewhere on this forum and I don't think it has changed the view of the protagonists on either side. But if we are to simply discuss the use of geomagnetic field data and not indulge in the childish sport of always having the last word, it is clear that this method does not in itself falsify 607.
