Lemnos.

From my reading, Lemnos seems to have been a golden center of
civilization from the Neolithic down to the start of the Iron Age.

If you pay attention to the geography, you see it is the biggest
island after exiting the Hellespont. Being a big island, it also has a
regular water supply. Being an island, it was pretty immune from
invasions until the advent of the Sea People. It is located within
easy rowing/sailing distance of the Hellespont, the mouth of the
Hebrus, the Struma, and even the Axios. It was ideally situated for
the exange of trade goods from South Central Europe and the Black Sea.

The one thing I want to know more about is the impression I have that
Lemnos seems to have been a paramount trade center during the Bronze
Age, the ultimate wholesale/retail center the Aegean. The island was
*wealthy*.

Finding odd inscriptions on Lemnos would be no more unexpected than
finding inscriptions in dozens of different languages in present-day
New York City.
