Lyrics:

Amarilli, mia bella,
Non credi, o del mio cor dolce desio,
D'esser tu l'amor mio?
Credilo pur: e se timor t'assale,
Dubitar non ti vale.
Aprimi il petto e vedrai scritto in core:
Amarilli, Amarilli, Amarilli, il mio amore.

English Translation:

My lovely Amaryllis,
Don’t you know, O my heart's sweet desire,
That it is you whom I love?
Believe in my love; and if fear besets you,
Don’t doubt that it’s true.
Open my breast and see written on my heart:
Amaryllis, Amaryllis, Amaryllis, is my love.
