One Winged Angel is a piece of music that plays during the last battle against Sephiroth in the Northern Cave. Though it's not the first fully orchestrated song in the Final Fantasy series, it is the first to appear in-game.

The words are taken directly from a famous opera piece called "Carmina Burana," written by Carl Orff, which in turn was based on a piece of thirteenth-century poetry found in a manuscript dubbed the Codex latinus monacensis.
