Armide is unusual among Lully and Quinault's tragédies lyriques in that it concentrates on the psychological development of a single character.
Armide leaves the Pleasures and a troop of Fortunate Lovers to amuse Renaud in an extended divertissement while she retires to the Underworld to consider her situation.
Armide returns in time to confront Renaud as he leaves her, imploring him to take her with him as a captive if he will not remain as her lover.
Armide's free declamatory recitatif is in dramatic contrast and with a change of mode indicates the difference in content of the speech; Armide is distressed.
As Armide and Hidraoth learn that the knight Renaud has freed their captives, they have an exclamatory duet of rage that is made rhythmically active by some quick syllabic text setting, and the Act ends.
Armide and La Haine engage in dramatic recitatif dialogue, and La Haine responds with an angry, lyrical solo and an oracle.
