that the Lacedaemonians having made a peace and league with the Athenians, their hitherto mortal enemies, tending not to the benefit, but to the enslaving of Peloponnesus, it behoved them to consider of a course for the safety of the same, and to make a decree that any city of the Grecians that would, and were a free city, and admitted the like and equal trials of judgment with theirs, might make a league with the Argives for the one mutually to aid the other; and to assign them a few men, with absolute authority from the state, to treat with; and that it should not be motioned to the people, to the end that, if the multitude would not agree to it, it might be unknown that ever they had made such a motion; affirming that many would come into this confederacy upon hatred to the Lacedaemonians.
These men of Argos having heard them and reported their proposition both to the magistrates and to the people, the Argives ordered the same accordingly and elected twelve men with whom it should be lawful for any Grecian to make the league that would, except the Lacedaemonians and Athenians, with neither of which they were to enter into any league without the consent of the Argive people.
