[Verginius Rufus]

The civilization of Thera had ties to the Minoan civilization, but the eruption which buried the ancient site on Thera occurred about the time the Mycenaeans were starting to flourish, so Thera may have had no influence on Mycenae.

Nevertheless there were many therapods in ancient Greece (and there are many still today). I remember seeing some when I was in Greece many years ago. They were turkeys (no doubt a legacy of the Ottoman period).

There's no link between a volcanic eruption and the destruction of the Minoan sites -- that indicates the arrival of the Mycenaeans. Herodotus wrote a nice chunk about Calliste/There/Santorini and nothing about any eruption. The caldera is very prehistoric (10s or 100s of 1000s of years old, perhaps on the order of the age of the caldera at Kos), and from antiquity we've got just one account of an eruption, about 200 BC.
