His scene opens with a prayer ("Gerechter Gott") for the aversion of
carnage, which changes to an agitated allegro ("Wo war ich?") as he
hears the great bell of the Capitol tolling the signal for slaughter.
The finale begins with a massive march, as the bells and sounds of
alarm are heard approaching again, and bands of citizens, priests and
monks, the high clergy, senators and nobles, pass and repass in quick
succession, at last followed by Rienzi, which is the signal for the
great battle-hymn, "Santo spirito cavaliere," which is to be sung with
great fire and energy, accompanied by great and small bells ringing
behind the scenes, the clash of swords upon shields, and full power of
chorus and orchestra. A dialogue follows between Adriano and Rienzi,
and then the various bands disappear singing the ritornelle of the
hymn. A great duet ("Lebwohl, Irene") ensues between Adriano and
Irene, which in its general outlines reminds one of the duet between
Raoul and Valentin in "The Huguenots." At its conclusion, after a
prayer by the chorus of women, the battle hymn is heard again in the
distance, gradually approaching, and the act closes with a jubilee
chorus ("Auf! im Triumpf zum Capitol"), welcoming the return of the
conquerors.

The fourth act is short, its principal numbers being the introduction,
terzetto and chorus ("Wer war's der euch hierher beschied?"), and the
finale, beginning with a somewhat sombre march of the cortége
accompanying Rienzi to the church, leading to the details of the
conspiracy scene, and closing with the malediction of the monks, "Vae,
vae tibi maledicto." The last act opens with an impressive prayer by
Rienzi ("Allmacht'ger Vater"), which leads to a tender duet ("Verlässt
die Kirche mich") as Irene enters, closing with a passionate aria by
Rienzi ("Ich liebte glühend"). The duet is then resumed, and leads to
a second and intensely passionate duet ("Du hier Irene!") between
