Can YOU identify this aria?

I should specify: can you identify this aria from a seconds-long clip I grabbed. I've attached it.

I'd love it if anyone could help me out. It's a lovely piece, but I'm terrible with deciphering lyrics and can't search for it that way.

Thanks =]

Intriguing. I have no idea. I even checked Musipedia, and they have no listing for it (they're far from comprehensive, but they generally have most of the well-known tunes in their database).
