Histories

As for the wife that you have, we do not ask that you send her away. Keep providing her with all that you give her now and marry another woman in addition who can give you children.” So they spoke, and Anaxandrides consented. Presently he had two wives and kept two households, a thing which is not at all customary at Sparta [22.4417,37.0667] (Perseus) Sparta.

After no long time the second wife gave birth to Cleomenes. She, then, gave the Spartans an heir to the royal power, and as luck would have it, the first wife, who had been barren before, conceived at that very time.

When the friends of the new wife learned that the other woman was pregnant, they began to make trouble for her. They said that she was making an empty boast, so that she might substitute a child. The Ephors were angry, and when her time drew near, they sat around to watch her in childbirth because of their skepticism.
