Lycurgus (13.5-13.6)

It was because he was used to this simplicity that Leotychides the Elder, as we are told, when he was dining in Corinth, and saw the roof of the house adorned with costly panellings, asked his host if trees grew square in that country. A third rhetra of Lycurgus is mentioned, which forbids making frequent expeditions against the same enemies, in order not to accustom such enemies to frequent defence of themselves, which would make them warlike.

And this was the special grievance which they had against King Agesilaüs in later times, namely, that by his continual and frequent incursions and expeditions into Boeotia he rendered the Thebans a match for the Lacedaemonians. And therefore, when Antalcidas saw the king wounded, he said: This is a fine tuition-fee which thou art getting from the Thebans, for teaching them how to fight, when they did not wish to do it, and did not know how. Such ordinances as these were called rhetras by Lycurgus, implying that they came from the god and were oracles.
