English Translation:
 

Nor is it useful for those who test the seas to break faith;
that place exacts the punishments for treachery,
especially when Love has been wounded, because the mother of Love,
having risen naked, as it is said, from the Cytherian waters.
Having been ruined, fear that I will ruin him, and that I will injure him who injures me,
and let the shipwrecked enemy not drink the waters of the sea.
Live, I pray!  Thus I desire to harm you less than by death;
rather, you will be considered as the cause of my own death.
Envision, do it, that you are being seized (may there be no importance in omens!)
by a rushing storm; what will you disposition be?
Further on, the perjuries of your false tongue will come rushing to you;
As well as Dido having been summoned by Trojan deceit to die.
The shade of your deceived wife will stand before your eyes
Heavy of heart and bloody with hair poured out
