Among the ancients, _Lycurgus_, the Spartan law-giver, regarded maternity as woman’s principal attribute, and considered the sexual impulse to be the means merely by which healthy citizens were provided for the state. In accordance with this view, the sanctity of marriage was violated, and every powerful, handsome, and valiant Spartan had the right to request the privilege of intercourse with the wife of another, in order to enrich that other’s family with his seed. Elderly, impotent men conducted well-formed young men into the arms of their own wives. The girls, like the young men, went through a course of gymnastic exercises, in order to harden their bodies, and to fit them for the bearing of strong and healthy children. No man might marry before attaining the age of thirty, no woman before attaining the age of twenty. Girls ripe for marriage were assembled in a dark place, and there the young men chose their brides, as chance might direct. The young men were allowed to visit their wives by night only, and secretly, in order that the vigor of the sexual impulse might be increased and maintained. Among the Spartans, it happened quite frequently, that a man whose wife had remained childless, and who believed himself to be at fault in the matter, would beg one of his fellow-countrymen, or even a foreigner, to come to his assistance. It was enacted by one of Solon’s laws, to prevent a man from neglecting his marital duties, that he should have intercourse with his wife not less than three times monthly. According to another of Solon’s laws, an Athenian heiress might call upon her nearest relative for the gratification of her sexual desires. The bluntest contrast to this Spartan simplicity is furnished by the unbridled lasciviousness that prevailed in Rome under the Cæsars, when women’s sole desire was sexual enjoyment, while maternity was a state to be avoided. To such an extreme was this carried, that the Roman ladies of that day preferred to marry eunuchs, and further, as _Pliny_ reports, hermaphrodites were in great request. _Juvenal_ writes: “There are women who prize the infertile embraces of base eunuchs; thus they are able to dispense with the use of abortifacients.” The hygiene of the nuptial night deserves from the physician more attention than it has hitherto generally received. He should warn and enlighten the young husband, in order that the brutality with which the act of defloration is apt to be performed may be lessened, and further in order that mistakes in this connection, resulting from ignorance and likely to have serious consequences, may be avoided. It is well known that lacerations of the hymen and its environment, and even serious injuries of the genital organs, may result from maladroit attempts at penetration. The physician will admonish the husband in the words of _Michelet_: “Bear in mind in this hour that thou art an enemy, a tender, considerate, and gentle enemy!”
