In Bellini's opera, Norma, the soprano's plea to the moon goddess in Act I begins Casta diva, and the aria is well known by that name.[5]
Plot
The film concerns Italian composer Vincenzo Bellini and his problems with his opera Norma (1831), which itself tells the passionate love story of a Gallican priestess of the local Celtic religion and a Roman proconsul (governor of a province). The film is unique because it uses abstract paintings-in-motion to express the passion between the two main characters.
