Classical music fans - help ID a track!!

It starts playing at 1:40, and gets absolutely gorgeous by 4:40. If anybody knows what piece of music this is, I will love you forever.

it's pretty nice...are you sure it's not a composition for the movie? like OST? seems a little too classy for that, but who knows...it's foreign, those fuckers are fancy sometimes. sounds 19 century to my very amateur ears, but i can't place it at all. i know next to nothing about classical though, only listen casually.

I love that movie.

It's not even credited in the closing titles, I just checked.

dunno the name of the track but pretty sure its the same tune used at about 2.00 thru this (past the eye gouging scene) + think I read somehwere this is some shit by
Wagner if that helps which it probably dosent
