And their oath shall be the greatest that by custom of the several cities is used, and with most perfect hosts, and in these words: 'I will stand to this league, according to the articles thereof, justly, innocently, and sincerely, and not transgress the same by any art or machination whatsoever.' "This oath shall be taken at Athens by the senate and the officers of the commons, and administered by the Prytanes.
At Argos it shall be taken by the senate and the council of eighty and by the Artynae, and administered by the council of eighty. At Mantineia it shall be taken by the procurators of the people and by the senate and by the rest of the magistrates, and administered by the theori and by the tribunes of the soldiers. At Elis it shall be taken by the procurators of the people and by the officers of the treasury and by the council of six hundred, and administered by the procurators of the people and by the keepers of the law.
"This oath shall be renewed by the Athenians, who shall go to Elis and to Mantineia and to Argos thirty days before the Olympian games; and by the Argives, Eleians, and Mantineans, who shall come to Athens ten days before the Panathenaean holidays.
"The articles of this league and peace and the oath shall be inscribed in a pillar of stone by the Athenians in the citadel; by the Argives in their market place within the precincts of the temple of Apollo; and by the Mantineans in their market place within the precinct of the temple of Jupiter. And at the Olympian games now at hand, there shall be jointly erected by them all a brazen pillar in Olympia [with the same inscription].
If it shall seem good to any of these cities to add anything to these articles, whatsoever shall be determined by them all in common council, the same shall stand good.
Thus was the league and the peace concluded; and that which was made before between the Lacedaemonians and the Athenians was, notwithstanding, by neither side renounced.
