HI Etepete
Thanks for your input.
I see no problem with people still seeing themselves as Thessalian etc just as people in many countries today still think of themselves as part of their families past regional location. American Italians, Bavarian Germans etc.
You have a good point about the Gymnasium, However. I think by this time it was open to more than just the high class and it would have subgroups within it.
From the Oxford history of Greece and the Hellenistic World
'in classical Athens there are signs that it was being made available to a far wider group' than just aristocrats p270
by the 'end of the forth century the Athenian system was sufficiently standard and universal to be completed by a state system of youth training, in which all young men from the age of 18 spent two years in the gymnasium and in military training' this 'became in Hellenistic period the mark of a Greek city and the chief distinction between citizen and non-citizen' p271
Thanks for your thoughts
