:Place: Rome and environs :Time: Around 970 AD The opera is based on events from the lives of
Adalbert of Italy and
Otto II. The "Argument" to the opera provides the context of the events that precede the opera. It had been arranged that Ottone would marry Teofane, daughter of Romano, the Eastern Emperor. Basilio, Teofane's brother, had been driven into exile by a usurper. However, Basilio had become a pirate during his exile, and took on the name of Emireno.
Act 1 A gallery adorned with statues Gismonda's dream is to see her son Adelberto on the throne of Italy. (Arioso:
Pur chi regni il figlio amato). When Adelberto comes to her, she informs him of her scheme to bring this to pass. Her deceased husband had ruled Italy illegally as the country was really a possession of the German King Ottone, who is now on the way to reclaim the territory and to marry Teofane, daughter of the Byzantine emperor, who is already in Rome and has been sent a portrait of her bridegroom-to-be, which has caused her to look forward to her marriage with delight. However Ottone has been delayed in his journey to Rome by an attack on his convoy of ships by pirates, necessitating a battle at sea. Gismonda instructs her son to present himself to Teofane as her bridegroom, and then marry her, pretending to be Ottone. Adelberto thinks this is a very clever plan and Gismonda joyfully anticipates her son's success. (Aria:
La Speranza è
Giunta in porto). Teofane comes to meet, as she believes, her husband-to-be Ottone, and when Adelberto greets her, pretending to be Ottone, she cannot understand why he looks nothing like the handsome and noble young man she had imagined from the miniature portrait she had been sent and carries with her in a locket. Left alone, she accuses the portrait of cruelly misleading her (Aria:
Falsa imagine).
Tents along the shore of the sea with ships at anchor The true Ottone has arrived to claim his rightful kingdom and his bride, and has defeated the pirate Emireno, who is brought before him in chains. Emireno hints that he is really someone very mighty but refuses to reveal his true identity and is led away. (Aria:
Del minacciar del vento). Ottone is now greeted by his enraged cousin Princess Matilda, who was officially engaged to Adelberto and is furious that he now proposes to marry Teofane instead. She informs Ottone that Gismonda and Adelberto are scheming against him. Ottone hopes that Teofane can still be his despite this (Aria:
Ritorna, o dolce amore). Matilda, alone, yearns for revenge against Adelberto for his jilting of her (Aria:
Diresti poi così). ''Throne room of Gismonda's palace'' Since her son Adelberto is now posing as Ottone, Gismonda poses as Ottone's mother
Adelaide in a meeting with Teofane. "Adelaide" haughtily instructs Teofane to give her son her heart as well as her hand (Aria:
Pensa ad amare), and leaves. Adelberto comes to lead Teofane to their wedding, but his mother reappears with the news that Ottone is invading with an army, thrusts a sword into her son's hand and sends him off to battle. Left alone, Teofane now realises that Adelberto is only pretending to be Ottone, and laments the position in which she finds herself (Aria:
Affanni del pensier).
A battlefield A
sinfonia is played as an onstage battle shows the defeat of Adelberto's army and his capture by Ottone's forces. Adelberto is led away, defiant but in chains (Aria:
Tu puoi straziarmi). Alone, Ottone is still hopeful of winning Teofane and the kingdom and ruling in peace, extending justice to all (Aria:
Dell’onda ai fieri moti).
Act 2 A brief orchestral sinfonia introduces the act.
A hallway in the palace On his way to prison, Adelberto is encountered by Matilda, who tells him he should never have accepted being engaged to her if he really loved Teofane instead. They are joined by Gismonda, who reproaches her son for being defeated in battle by Ottone. Adelberto hopes that he will learn fidelity from Matilda's example, and is led away (Aria:
Lascia, che nel suo viso). Matilda and Gismonda are both distraught at Adelberto's defeat and imprisonment. Matilda thinks they should beg Ottone for mercy, but Gismonda would prefer that she and her son both be put to death rather than thus abase themselves. Matilda says she will not allow that to happen, Adelberto must be freed (Aria:
Ah! Tu non sai). When alone, Gismonda admits to herself that she too feels pity for her son and longs to console him in his distress (Aria:
Vieni, o figlio, e mi consola). Teofane and Ottone are about to meet face to face for the first time, both looking forward to this, but Matilda suddenly appears and throws herself at Ottone's feet, begging him for mercy for Adelberto. Teofane withdraws into an alcove and watches as Ottone declines to pardon Adelberto but embraces Matilda in an attempt to console her. Teofane misinterprets this gesture as a sign that Ottone is in love with Matilda. In any case, the embrace does nothing to cool Matilda; she fulminates against Ottone for his refusal to show clemency to Adelberto, calling on monsters and furies to pursue him (Aria:
All’orror d’un duolo eterno). When Teofane and Ottone finally meet, she accuses him of falsely pretending he is not in love with another (Aria:
Alla fama, dimmi il vero) and, once on his own, Ottone prays that this storm will subside (Aria:
Dopo l’orrore).
A delightful garden by the Tiber with springs and caves, and an underground passage closed by a stone. Night Teofane walks dejectedly in the garden, feeling utterly alone (Aria:
S’io dir potessi). Emireno and Adelberto emerge from the tunnel, pushing the stone aside. They have escaped from prison with the help of a map sent to them by Matilda. Emireno looks forward to freedom and to vanquishing the enemies who have wronged him (Aria:
Le profonde vie dell’onde). Emireno goes to find the boat Matilda has told him will be waiting, and Matilda herself, then Ottone arrive, Matilda looking for the tunnel and Ottone in search of Teofane. Adelberto and Teofane conceal themselves as Matilda guides Ottone away, telling him it is not safe for him to wander around at night alone. Ottone is more concerned about Teofane than himself (Aria:
Deh! Non dir). Emireno has found the boat and returns, and Adelberto seizes Teofane, who swoons as he carries her into the boat and rows her away, together with Emireno and some of their men. Gismonda joins Matilda in the garden; they celebrate the night that saw the success of their plan to free Adelberto (Duet:
Notte cara).
Act 3 A room in the palace Ottone is desolate that Teofane has vanished (Aria:
Dove sei, dolce mia vita). Gismonda comes to him and gloats that her son has escaped (Aria:
Trema, tiranno). Ottone feels betrayed and abandoned by everyone (Aria:
Tanti affanni).
A wood with a view of the Tiber After a brief orchestral sinfonia, Adelberto, Emireno and Teofane appear with their guards. Their escape has been stalled by a sudden squall that has blown up. Adelberto hopes both for better weather and for Teofane's love (Aria:
D’innanlzar i flutti al ciel). He leaves to look for a dwelling where they can take refuge from the storm. Alone with Emireno, Teofane demands respect as the daughter of Romano, King of Byzantium. At this, Emireno attempts to embrace her, and Teofane, as well as Adelberto who returns just as this takes place, misinterpret the action as an attempt at seduction. Adelberto attacks Emireno but the guards seize him. Teofane is distraught and asks the guards to kill her, death will be a release (Aria:
Benchè mi sia crudele). Emireno tells her she has no reason to be afraid (Aria:
No, non temere, o bella). Teofane imagines Ottone in Matilda's arms, but even so, she swears she will love him always (Aria:
Gode l’alma consolata).
A room in the palace Matilda tells Ottone that Adelberto has abducted Teofane. Gismonda is triumphant at her son's actions, but Matilda tells her she will change her tune when she sees her son's head cut from his shoulders. Gismonda retorts by revealing to Ottone that it was due to Matilda that Adelberto managed to escape. Matilda admits this is true, but she is sorry she helped Adelberto and would now like to kill him herself (Aria:
Nel suo sangue). Emireno comes in with Adelberto in chains. Ottone orders Adelberto to be executed, but Matilda demands the right to run him through herself. However she cannot bring herself to do it, realising that she still loves him. Gismonda grabs the knife from Matilda and is about to commit suicide, when Teofane rushes in and she and Ottone are joyfully reunited (Duet:
A’ teneri affetti). Teofane explains that she now knows that Emireno is really her brother; Gismonda and Adelberto ask for and receive Ottone's forgiveness and pledge him their loyalty, and Matilda accepts Adelberto's offer of marriage. All celebrate the fortunate turn of events (Chorus:
Faccia ritorno l’antica pace). ==Musical features==
