Freitag aus Licht (Friday from Light), the main body of which is also titled Freitag-Versuchung (Friday Temptation), is the fifth to be composed of the seven operas that comprise Licht (Light), by Karlheinz Stockhausen. It was the last of the operas to receive a staged production with the composer's involvement. Freitag is the Day of Temptation, where the Licht antagonist Lucifer (here represented by the character "Ludon") attempts to lure the female protagonist Eve into bonding with his son, "Caino", and joining his revolution against Heaven (and the hero Michael).
