While traveling in Egypt with her husband Eugène Olagnier, it is believed that she wrote both words and music of an "exotic opera" in four acts, Le Saïs [fr],[1] which "aimed at the fantasies and desires of women."[2] It was staged at the Théâtre de la Renaissance in Paris on 18 December 1881 and was later performed by Victor Capoul, an Opéra-Comique tenor.[2]
Later in life she directed her own company, the Théâtre de l'Oratorio, in weekly performances of 18th- and 19th-century oratorios. Olagnier also composed a number of songs and two more operas, Le Persan and Lilipa, which were never performed. Her only known novel was never finished.[3]
