Ah! mio cor! schernito sei!
Stelle! Dei! Nume d?amore!
Traditore! T?amo tanto;
puoi lasciarmi sola in pianto,
oh dei! perché?
 
Ma, che fa gemendo Alcina?
Son reina, è tempo ancora:
resti o mora, peni sempre,
o torni a me.

Ah! My heart! Tanted are you!
Stars! Gods! God of love!
Traitor! I love you so much;
you can leave me alone crying,
oh gods! Why?
 
But, what is Alcina doing whining?
I'm queen, it's still time:
Stay or die, hurt forever,
or come back to me.
