|This is Sparta!|
I was tinkering and put together this hex map of the area we usually call Ancient Greece (download it; it's a lot better than the preview makes it look). Not everything - Crete is probably the biggest missing part, but also the northern area, including Thessalonika. And of course there's nothing of the Italian/Sicilian colonies to the west which everyone always forgets about.
The big hexes are 36miles and inside them are 6 mile hexes (don't forget: a 6 mile hex is still 20,000 acres).
The map itself is the size of a single index mapsheet in my Campaign Map Book by sheer luck rather than intent. But the 6:1 ratio is ideal for that if you fancy splashing some cash my way.
Here's a little index for the map which I'll try to update from time to time:
