Having established a sanctuary of Syllanian Zeus and Athena, having tribed tribes and obed obes, and having established a Gerousia (Senate) of thirty members, including the (two) chief leaders (kings), from season to season, they are to hold Assemblies between Babyca and Knakion in order to introduce and reject measures. And the damos is to have lordship and power. "Later a clause was added: if the damos takes a crooked decision, the elders and chief leaders are to be removers."
