Sorry, that's what comes of typing off the top of your head. It's been almost 30 years since I took that Greek Archaeology course . . . I was thinking of the earlier disaster, possibly a Mycenaean invasion (although some think it was the eruption of Thera) that toppled the early Cretan palace culture around 1700 B.C. There had been a lot of cross-cultural exchange before that (hence the Linear B). Prof. Blegen thinks the Dorians came waltzing in somewhere around 1200 B.C. and destroyed the Cretan civilization utterly.
If you haven't been to Thera, it is well worth a trip. Beautiful, beautiful views. Also, there is a site currently being excavated that you can visit.
