Fausta
Empress Fausta falls in love with her stepson Crispo, who loves the captive Beroe. After Fausta’s advances are exposed, Crispo is condemned for treason through the schemes of her father Massimiano. Fausta tries to save him with poison, but the execution has already occurred. Constantine receives proof of Crispo’s innocence too late; Fausta dies, and Massimiano is exposed.
