[The Velveteen Ocelot]

11. "Senza mamma" by Puccini

This aria is from the opera Suor Angelica. A young noblewoman has been sent to a convent because she had an illegitimate child. After a number of years her cruel aunt comes to visit her to get her to sign away her inheritance, and informs Sister Angelica that her baby has died. This is probably the saddest aria ever.

Without your mother, o my baby, you are dead!
Your lips, without my kisses, grow pale and cold!
And close, o baby, your pretty eyes.
I cannot caress you, your little hands composed in a cross!
And you are dead without knowing how loved you were by your mother!
Now you are an angel in heaven, now you can see your mother,
you can descend from heaven and let your essence linger around me.
Are you here, do you feel my kisses and caresses? Ah! tell me, when will I see you in heaven?
When will I be able to kiss you? Oh, sweet end to all my sorrows, when I greet you in heaven.
When will I greet death? Tell your mother, beautiful creature, with a sparkle of the stars.
Speak to me, my loved one!
