Fedora is an opera in three acts by Umberto Giordano to an Italian libretto by Arturo Colautti, based on the 1882 play Fédora by Victorien Sardou.

It was first performed at the Teatro Lirico in Milan on 17 November 1898 conducted by the composer; Gemma Bellincioni created the role of Fedora with Enrico Caruso as her lover, Loris Ipanov.

The opera had great success on its opening night, and was soon brought to the Vienna Staatsoper by Mahler, and then to Paris where it was reportedly admired by Massenet and Saint-Saëns.

Doctors and a priest are summoned, and the servants are questioned (Dimitri: "Signore, alle otto e mezzo"; Cirillo: "Egli mi disse").

Fedora swears on the jeweled Byzantine cross she is wearing (aria: "Dite coragio ... Su questa santa Croce") that Andrejevich's death will be avenged.

There is a reception at Fedora's house, where the Countess Olga Sukarev introduces the virtuoso Polish pianist Boleslao Lazinski.

De Siriex sings about Russian women ("La donna russa è femmina due volte"); Olga counters with an aria comparing Parisian gentlemen with the wine of the widow Veuve Clicquot ("Eccone un altro più somigliante ancor").

The Bernese Oberland in Switzerland Ipanov and Fedora are now lovers (his brief aria: "Te sola io guardo") and living in her villa.

He tells Fedora that as a result of the letter she wrote to the police chief, Ipanov's brother Valeriano was arrested for his role in the plot to murder Vladimir and imprisoned in a fortress on the Neva river.

Orchestra Lirica e Coro di Milano della RAI 5050466-2909-2-2 "Amor ti vieta" ("Love forbids you") is the most famous aria from the opera and is often sung by tenors in recitals, especially as an encore piece.

This short aria (approximately 1:51 minutes) is sung by Count Loris when he declares his love to Fedora in Act II.
