I have long thought that as Crete fell into eclipse after its maritime strength was destroyed by tsunamis from Thera, that artists and artisans may have made there way to Egypt and more specifically Amarna. In addition I imagine that mainland Greeks also made their way to Crete and thence to Egypt. There was definitely commerce between the two.
The commerce happened because of ships, not tsunamis — and not least because there were none from Santorini.
