                                        Era la notte allor ch'alto riposo
Han l'onde e i venti, e parea muto il mondo,
Gli animai lassi, e quei che 'l mare ondoso,
O de' liquidi laghi alberga il fondo,
E chi si giace in tana, o in mandra ascoso,
E i pinti augelli nell’oblio giocondo
Sotto il silenzio de' secreti orrori
Sopían gli affanni, e raddolciano i cori.
