Actually I wasn’t thinking of these Greeks being attacked, but rather to what extent they might have been a part of the Sea People’s activities. Regarding two fine bull cups, I wonder if these might have been a relic of the bull leaping cults of Crete. I would love to see what they looked like for further clues.
Google "Vapheio cups" and the first item is "images of Vapheio cups" which has a lot of good photos of them. The Wikipedia article "Vaphio" also has a link to some images but they aren't as close-up.
