16. These kings were suited to younger years, whilst he was ripening with the gray hairs of age; but when a virgin has gained the triumph over her subdued body, she should lessen her toil, that she may be preserved as teacher for a younger age. The vine laden with the fruitful branches of full growth soon breaks unless it be from time to time kept back. But whilst it is young let it grow rank, and as it grows older be pruned, so as not to grow into a forest of twigs, or die deprived of life by its exceptive produce. A good husbandman by tending the soil keeps the vine in excellent order, protects it from cold, and guards it from being parched by the mid-day sun. And he works his land by turns, or if he will not let it lie fallow, he alternates his crops, so that the fields may rest through change of produce. Do you too, a veteran in virginity, at least sow the fields of your breast with different seeds, at one time with moderate sustenance, at another with sparing fasts, with reading, work, and prayer, that change of toil may be as a truce for rest.
