He ordered the virgins to exercise themselves in running, wrestling, and throwing quoits and darts; that their bodies being strong and vigorous, the children afterwards produced from them might be the same; and that, thus fortified by exercise, they might the better support the pangs of child-birth, and be delivered with safety.

Yet he might by selection do something not only for the bodily constitution and frame of his offspring, but for their intellectual and moral qualities.
