13. Cato expelled from the Senate a man who had kissed his own wife in the presence of his daughter. This, perhaps, was too severe a step. But if—as is the case—it is unseemly to be fondling and kissing and embracing each other in company, it is surely more unseemly to be scolding and quarrelling in company, and, while treating your love-passages as a sacred secret between you and your wife, to make an open display of fault-finding [Sidenote: F] and reproach.

14. A mirror,[37] though decorated with gold and precious stones, is of no use unless it shows you your form true to life. Similarly there is no advantage in a rich wife, if her conduct does not represent that of her husband and harmonize with it in character. If the reflection which it offers is glum when you are joyful, but wears a merry grin when you are gloomy and distressed, the mirror is faulty and bad. A wife is a poor thing and out of place if she is in the dumps when her husband is disposed for frolic or love-making, but is all fun and laughter when he is serious. In the former case she is disagreeable; in [Sidenote: 140] the latter, she slights you. Geometers tell us that lines and surfaces make no movement by themselves, but only in conjunction with the bodies to which they belong. In the same way a woman should be free from peculiar states of mind of her own, but should act as the husband’s partner in his earnestness and his jest, in his preoccupation and his laughter.

15. A man who dislikes to see his wife eating with him, teaches her to satisfy her appetite when she gets by herself. Similarly one who is never a merry companion to her, nor shares in her sport and laughter, teaches her to look for private pleasures apart from him.

[Sidenote: B] 16. When the Persian kings are dining or feasting, their legitimate wives sit at their side. But when they wish to amuse themselves or get tipsy, they send those wives away and summon their minstrel-women and concubines. The practice is a right one, at least to the extent that they do not permit their wives to take part in wanton and licentious scenes. So, if a private man, who lacks self-control or good-breeding in his pleasures, is guilty of a lapse with a common woman or a menial, the wife should not be indignant and resentful, but should reflect that, out of respect for her, he finds some other woman to share his riot and lasciviousness.
