"The freedom which thus prevailed at that time in marriage relations was aimed at physical and political well-being, and was far removed from the licentiousness which was afterwards attributed to their women, so much so that adultery was wholly unknown among them. And a saying is reported of one Geradas, a Spartan of very ancient type, who, on being asked by a stranger what the punishment for adulterers was among them, answered: "Stranger, there is no adulterer among us." "Suppose, then," replied the stranger, "there should be one." "A bull," said Geradas, "would be his forfeit, a bull so large that it could stretch over Mount Taÿgetus and drink from the river Eurotas." Then the stranger was astonished and said: "But how could there be a bull so large?" To which Geradas replied, with a smile: "But how could there be an adulterer in Sparta?" Such, then, are the accounts we find of their marriages."
