The Achaean league, which had to expect neither profit
nor immediate injury from the thirst of Philip for aggrandizement,
alone in all Greece looked at this war from an impartial and national-
Greek point of view.
It perceived--what there was no difficulty in
perceiving--that the Greek nation was thereby surrendering itself
to the Romans even before these wished or desired its surrender, and
attempted accordingly to mediate between Philip and the Rhodians;
but it was too late.
The national patriotism, which had formerly
terminated the federal war and had mainly contributed to bring about
the first war between Macedonia and Rome, was extinguished the Achaean
mediation remained fruitless, and in vain Philip visited the cities
and islands to rekindle the zeal of the nation--its apathy was the
Nemesis for Cius and Abydus. The Achaeans, as they could effect
no change and were not disposed to render help to either party,
remained neutral.
