My money is with the geophysists.
I've heard theorizing that the There eruption might account for the biblical plagues that occured at the time of Moses.
if I kick over a rock while I'm there, will I qualify for a grant?
I have a whole book on the Thera eruption, and they clearly favor the 1646-1626 figures. Apparently it had serious eruptions that scared all the people away and then 2 decades later blew its top.
I know that historians favor 1500 BC because of the decline of the Minoan civilization, but I wonder if that could have been caused by the very major eruption of Etna which took place 1500 BC, +- 50 years. I wish I could find more about that eruption.
