Touching next upon the training of a virgin, he speaks of moderation in food and drink, and of restraint upon the impulses of the mind, introducing some teaching upon the fable of the death and resurrection of Hippolytus, and advises the avoidance of certain meats.
5. But sometimes even when faith is to be relied upon, youth is not trusted. Use wine, therefore, sparingly, in order that the weakness of the body may not increase, not for pleasurable excitement, for each alike kindles a flame, both wine and youth. Let fasts also put a bridle on tender age, and spare diet restrain the unsubdued appetites with a kind of rein. Let reason check, hope subdue, and fear curb them. For he who knows not how to govern his desires, like a man run away with by wild horses, is overthrown, bruised, torn, and injured.
6. And this is said to have happened to a youth for his love of Diana. But the fable is coloured with poet's tales, that Neptune, stirred with grief at his rival being preferred, sent madness upon his horses, whereby his great power might be set forth in that he overcame the youth, not by strength, but by fraud. And from this event a yearly sacrifice is celebrated for Diana, when a horse is offered at her altar. And they say that she was a virgin, and (of which even harlots would be ashamed) yet could love one who did not love her. But as far as I am concerned let their fables have authority, for though each be criminal, it is yet a less evil that a youth should have been so enamoured of an adulteress as to perish, than that two gods should, as they relate, contend for committing adultery, and that Jupiter avenged the grief of his daughter who played the harlot on the physician who cured the wound of him who had violated Diana in the woods, a most excellent huntress, no doubt, not of wild beasts, but of lust: yet also of wild beasts, so that she was worshipped naked.
7. Let them ascribe, then, to Neptune the mastery over madness, in order to fix on him the crime of unchaste love. Let them ascribe to Diana the rule over the woods, wherein she dwelt, so as to establish the adultery which she practised. Let them ascribe to Æsculapius the restoration of the dead so long as they confess that when struck by lightning he himself escaped not. Let them also ascribe to Jupiter the thunderbolts which he did not possess, so that they witness to the disgrace with which he was laden.
8. And I think that one should sparingly eat all kinds of food which cause heat to the limbs, for flesh drags down even eagles as they fly. But within you let that bird of which we read, “Your youth shall be renewed like the eagle's,” holding its course on high, swift in its virgin flight, be ignorant of the desire for unnecessary food. The gathering of banquets and salutations must be avoided.
