Adversus naturam pec-
cantes.[1]

Those sinning against nature.

Turpe quidem factu. sed & est res improba dictu, [2]
Excipiat si quis choenice ventris onus.
Mensuram legisque modum hoc excedere sanctae est,
Quale sit incesto pollui adulterio.[3]

It is certainly foul as a deed but also a wicked thing to speak of, if someone were to empty the burden of his bowels into a bushel-box. This means exceeding the measure and limit of divine law as it would be defiled by impure adultery.
