When a boy was punished by anybody, if he told his father, it was a disgrace for his father, upon hearing this, not to give him another beating; for they had confidence one in another, as the result of their ancestral discipline, that no one had ordered their children to do anything disgraceful.[*](Cf. Xenophon, Constitution of Sparta, 6. 2.)
