The oath shall be taken at Athens by the Senate and the magistrates, the Prytanes administering it; at Argos by the Senate, the Eighty, and the Artynae, the Eighty administering it; at Mantinea by the Demiurgi, the Senate, and the other magistrates, the Theori and Polemarchs administering it; at Elis by the Demiurgi, the magistrates, and the Six Hundred, the Demiurgi and the Thesmophylaces administering it.

The oaths shall be renewed by the Athenians going to Elis, Mantinea, and Argos thirty days before the Olympic games; by the Argives, Mantineans, and Eleans going to Athens ten days before the great feast of the Panathenaea.

The articles of the treaty, the oaths, and the alliance shall be inscribed on a stone pillar by the Athenians in the citadel, by the Argives in the market-place, in the temple of Apollo; by the Mantineans in the temple of Zeus, in the market-place; and a brazen pillar shall be erected jointly by them at the Olympic games now at hand.
