11 When you go a short way into the country, do not leave your daughter behind you. Leave her no power or capacity of living without you, and let her feel frightened when she is left to herself. Let her not converse with people of the world or associate with virgins indifferent to their vows. Let her not be present at the weddings of your slaves and let her take no part in the noisy games of the household. As regards the use of the bath, I know that some are content with saying that a Christian virgin should not bathe along with eunuchs or with married women, with the former because they are still men, at all events in mind, and with the latter because women with child offer a revolting spectacle. For myself, however, I wholly disapprove of baths for a virgin of full age. Such an one should blush and feel overcome at the idea of seeing herself undressed. By vigils and fasts she mortifies her body and brings it into subjection. By a cold chastity she seeks to put out the flame of lust and to quench the hot desires of youth. And by a deliberate squalor she makes haste to spoil her natural good looks. Why, then, should she add fuel to a sleeping fire by taking baths?
