I noticed a few small things in the larger Isocrates piece.  At the start he mentioned a Spartan colony that was much better placed than the Athenian colony that Athens was warring with Macedonia over.  I just thought this was odd because by the context of it, it seemed like this was a recent settlement.  What struck me about that was that I'm pretty sure this was when Sparta was essentially at the peak of its demographic crisis.  It just doesn't seem like the best time to send some of your already few citizens to found another city. 

Also I thought it was strange that I don't remember seeing Corinth mentioned at all in that document.  I generally think of Corinth before I think of the Argives, but they are mentioned all over the place, while Corinth is as far as I can remember completely ignored. I just thought that was odd.
