There are men who like nothing better than deflowering virgins—that is, who take the greatest pleasure in virgins and in robbing them of their virginity without any thought of marriage or children. When they have stolen the bloom of their virginity, they abandon them in disgust or prostitute them.
Men who have lived this kind of life have contravened the order of nature, of the spirit, and of heaven. They violate not only marriage love, a love held very sacred in heaven, but also innocence, which they wound and murder when they take innocent girls, who could have had the love of marriage instilled in them, and introduce them instead to the life of a whore. (People know that the first blossoming of love is what introduces young women to the chaste love in marriage and unites the minds of married partners.)
Because heaven’s holiness is founded on marriage love and innocence, and these men are inward murderers (as described), in the other life they suffer punishment of the most severe kind. They seem to themselves to be riding a frenzied horse that bucks them up into the air, throwing them off, apparently in danger of their lives; such is the terror that strikes them. Later they see themselves under the belly of the maddened horse and soon seem to go up through the horse’s rump into its stomach. Then suddenly it appears to them as if they are in the belly of a woman, a foul slut, who changes into a huge dragon. There they remain hidden and in pain. This punishment recurs many times over hundreds and thousands of years, until the offenders gain a horror for such desires.
I have heard that their children are worse than others, since they inherit this quality from their fathers. Accordingly, when people of this kind engage in sexual intercourse, it rarely produces offspring, and such babies as are born do not live long.
