never said they would not.
However I think the Hellenic model is a bit differnt in that it was not “just a spot” but an actual archetected location with that intention from the start.
For example to the right of the picture above near the plaka is a water clock mechanism (I have actually been there and there is an excellent History Channel documentary covering it) which told time for the whole area.
It was more than just a “village” level of transactions and discourse, it was a commercial draw for surrounding villages. Its creation is akin to our modern day creation of supermalls with clubs and theaters.
either way its is all good.
Later, of course, but the agora began as a place for the surrounding farmers to sell their food to the town-dwellers. The same set-up has been used all over the world, for many centuries. I will grant you that the Greeks made good use of it for politics, but I'm sure other cultures had the same thing. The Romans copied the Forum from the Greek agora, but the Greeks probably copied it from somebody else.
