Quest’ oltraggio è fatto ai Dei,
I quai, se non han cura di se stessi,
Non vi curate voi di vendicarli.

Translation: This is an insult offered to the Gods, And if the Gods themselves make light of it. It is not in your hands that vengeance lies. | Translation reported in Harbottle's Dictionary of quotations French and Italian (1904), p. 403.
