History of the Peloponnesian War

And that if any controversy arise between any of the cities, either within or without Peloponnesus, about limits or other matter, they also shall decide it. That if any confederate city be at contention with another, it shall have recourse to that city which they both shall think most indifferent; but the particular men of any one city shall be judged according to the law of the same.

Thus was the peace and league concluded; and whatsoever one had taken from the other in the war, or whatsoever one had against another otherwise, was all acquitted. Now, when they were together settling their business, they ordered that the Argives should neither admit herald nor ambassage from the Athenians till they were gone out of Peloponnesus and had quit the fortification, nor should make peace or war with any without consent of the rest.
