Heh... those who have a big woody about pushing back the date of the supposed super-eruption have made the problem even worse; used to be the conventional date for the sudden fall of the palatial civ on Crete was 70 years or so after the supposed eruption — now as you said it’s nearly 200. That chunk of pumice found in Egypt that had been used as a serving tray or something had been saddled on as evidence of the super-eruption of Thera — until it was actually studied and found to have come from an eruption of Kos 100s of 1000s of years ago. At that point it was cast aside, and just as Zangger pointed out, the delusional system was further strengthened by abandonment of yet another key piece of evidence. :’D
As I mentioned years ago I used to correspond with Zangger but I also do due diligence, Ebbi may be a semi-loon at this point in time but he raises some questions.
