Ancestry of Greek vessel names; Snakes on Athena; Illyrian magistra

Yesterday, I paid a long-overdue visit to the Royal Ontario Museum. I
was more happy than ever to visit the Ancient Greek section,
especially since they now had some Cycladic and Ancient Cypro-Minoan
wares, though dang it all, they didn't have any Linear A, and the one
picture of a Linear B tablet was untranslated. Even so, I managed to
copy a list of the main different kinds of Ancient and Classical
Greek vessels.
Throughout my visit, I had Indo-European on my mind. I'd love to know
which of these words might be of Indo-European origin. It'd certainly
be a fine connection with archaeology if we could find similar names
for vessels and ceramic wares in seperated and/or old IE cultures.

Noticing a reconstruction of the Great statue of Athena, I saw a
large snake between her and her shieldm and a great many small ones
on her breastplate. What did this signify?

Finally, I spotted a piece of money with the name of an Illyrian
magistrate's name on it, but it's impossible for me to know where the
name starts, as it goes around a square.
