In the meantime it was determined by the boeotarchs and the Corinthians, the Megarians, and the envoys from Thrace, first, to bind themselves by oaths one to another, that assuredly when occasion offered they would assist the one that needed help and would not go to war with anyone or make peace without a common agreement; and that then and only then the Boeotians and the Megarians—for they were acting in concertcf. 5.31.6.— should make a treaty with the Argives.
But before the oaths were sworn the boeotarchs communicated these resolutions to the four councils of the Boeotians which have supreme authority, and recommended that oaths be exchanged with such cities as wished to take oaths with them for mutual assistance.
