Place: Scotland
Time: 11th century
Act 1
Scene 1: A heath
Groups of witches gather in a wood beside a battlefield, exchanging stories of the "evils" they have done. The victorious generals Macbeth and Banco enter. The witches hail Macbeth as Thane of Glamis (a title he already holds by inheritance), Thane of Cawdor, and king "hereafter." Banco is greeted as "lesser than Macbeth, but greater", never a king himself, but the progenitor of a line of future kings. The witches vanish, and messengers from the king appear naming Macbeth Thane of Cawdor. Macbeth protests that the holder of that title is still alive, but the messengers reply that the former Thane has been executed as a traitor. Banco, mistrusting the witches, is horrified to find that they have spoken the truth. In a duet, Macbeth and Banco muse that the first of the witches' prophecies has been fulfilled. Macbeth ponders how close he is to the throne, and whether fate will crown him without his taking action, yet dreams of blood and treachery: while Banco ponders on whether the minions of Hell will sometimes reveal an honest truth in order to lead one to future damnation.
Scene 2: Macbeth's castle
Lady Macbeth reads a letter from her husband telling of the encounter with the witches. She is determined to propel Macbeth to the throne - by fair means or foul.
[Revised version, 1865: Vieni! t'affretta!/ "Come! Hurry!"]
Lady Macbeth is advised that King Duncan will stay in the castle that night; she is determined to see him killed (Or tutti, sorgete / "Arise now, all you ministers of hell"). When Macbeth returns she urges him to take the opportunity to kill the King. The King and the nobles arrive and Macbeth is emboldened to carry out the murder (Mi si affaccia un pugnal? / "Is this a dagger which I see before me?"), but afterwards is filled with horror. Disgusted at his cowardice, Lady Macbeth completes the crime, incriminating the sleeping guards by smearing them with Duncan's blood and planting on them Macbeth's dagger. Macduff arrives for an appointment with the King, while Banco stands guard, only for Macduff instead to discover the murder. He rouses the castle while Banco also bears witness to the fact of Duncan's murder. The chorus calls on God to avenge the killing (Schiudi, inferno, . . / "Open wide thy gaping maw, O Hell").
Act 2
Scene 1: A room in the castle
Macbeth is now king: Duncan's son Malcolm has fled the country, suspicion having conveniently fallen on him for his father's murder: but Macbeth is still disturbed by the prophecy that Banco, not he, will found a great royal line. To prevent this he tells his wife that he will have both Banco and his son murdered as they come to a banquet.
[1865 revised version: In her aria, La luce langue / "The light fades", Lady Macbeth exults in the powers of darkness]
Scene 2: Outside the castle
A gang of murderers lie in wait. Banco, sensing danger shares his misgivings with his son. (Come dal ciel precipita / "O, how the darkness falls from heaven"). The murderers attack and stab him to death, but his son escapes.
Scene 3: A dining hall in the castle
Macbeth receives the guests and Lady Macbeth sings a brindisi (Si colmi il calice / "Fill up the cup"). The assassination is reported to Macbeth, but when he returns to the table the ghost of Banco is sitting in his place. Macbeth raves at the ghost and the horrified guests believe he has gone mad. Lady Macbeth manages to calm the situation once - and even mocks it by calling for a toast to the absent Banco (whose death is not yet public knowledge), only for the ghost to appear a second time and terrify Macbeth into insanity again. Macduff resolves to leave the country, saying it is ruled by a cursed hand and only the wicked may remain: the other guests are terrified by Macbeth's talk of ghosts, phantoms and witches. The banquet ends abruptly with their hurried, frightened departure.
Act 3
The witches' cave
The witches gather around a cauldron in a dark cave. Macbeth enters and they conjure up three apparitions for him. The first advises him to beware of Macduff. The second tells him that he cannot be harmed by a man 'born of woman'. The third that he cannot be conquered till Birnam Wood marches against him. (Macbeth: O lieto augurio / "O, happy augury! No wood has ever moved by magic power")
Macbeth is then shown the ghost of Banco and his descendants, eight future Kings of Scotland, verifying the original prophecy. (Macbeth: Fuggi regal fantasima / "Begone, royal phantom that reminds me of Banco"). He collapses, but regains consciousness in the castle.
[Original 1847 version: The act ends with Macbeth recovering and resolving to assert his authority: Vada in fiamme, e in polve cada / "Macduff's lofty stronghold shall / Be set fire....".]
A herald announces the arrival of the Queen (Duet: Vi trovo alfin! / "I've found you at last"). Macbeth tells his wife about his encounter with the witches and they resolve to track down and kill Banco's son, as well as Macduff and his family (whom they do not yet know has already fled the country). (Duet: Ora di morte e di vendetta / "Hour of death and of vengeance").
Act 4
Scene 1: Near the border between England and Scotland
Scottish refugees stand near the English border (Chorus: Patria oppressa / "Down-trodden country"):
[Original 1847 version: While each version uses the same libretto, the music of this chorus is different. It begins with a less ominous, much shorter orchestral introduction and is sung straight through by the entire chorus.]
[1865 revised version: the music is divided into sections for the male and female members, then it unites them towards the end. The revised version is 2 minutes longer than the original.]
In the distance lies Birnam Wood. Macduff is determined to avenge the deaths of his wife and children at the hands of the tyrant (Ah, la paterna mano / "Ah, the paternal hand"). He is joined by Malcolm, the son of King Duncan, and the English army. Malcolm orders each soldier to cut a branch from a tree in Birnam Wood and carry it as they attack Macbeth's army. They are determined to liberate Scotland from tyranny (Chorus: La patria tradita / "Our country betrayed").
Scene 2: Macbeth's castle
A doctor and a servant observe the Queen as she walks in her sleep, wringing her hands and attempting to clean them of blood (Una macchia è qui tuttora! / "Yet here's a spot"). She raves about the deaths of both Duncan and Banco, and even about the deaths of Macduff's family, and that all the perfumes of Arabia would not clean the blood off her hands: all are things that the horrified witnesses would never dare to repeat to any living man.
Scene 3: The battlefield
Macbeth has learned that an army of Scottish rebels backed by England is advancing against him, but is reassured by remembering the words of the apparitions, that no man born of woman can harm him. However, in an aria (Pietà, rispetto, amore / "Compassion, honour, love") he contemplates the fact that he is already hated and feared: there will be no compassion, honour and love for him in his old age even if he wins this battle, nor kind words on a royal tomb, only curses and hatred. He receives the news of the Queen's death with indifference. Rallying his troops he learns that Birnam Wood has indeed come to his castle. Battle is joined.
[Original 1847 version's ending: Macduff pursues and fights Macbeth who falls. He tells Macbeth that he was not "born of woman" but "ripped" from his mother's womb. Fighting continues. Mortally wounded, Macbeth, in a final aria - Mal per me che m'affidai / "Trusting in the prophecies of Hell" - proclaims that trusting in these prophecies has caused his downfall. He dies on stage, while Macduff's men proclaim Malcolm to be the new King.]
Macduff pursues and fights Macbeth who falls wounded. He tells Macbeth that he was not "born of woman" but "untimely ripped" from his mother's womb. Macbeth responds in anguish (Cielo! / "Heaven") and the two continue fighting, then disappear from view. Macduff returns indicating to his men that he has killed Macbeth. He then turns to Malcolm, hailing him as King. The scene ends with a hymn to victory sung by bards, soldiers, and Scottish women (Salve, o re!/ "Hail, oh King!). Malcolm as King, and Macduff as hero, together swear to restore the realm to greatness.

Place: Mantua
Time: the sixteenth century
Act 1
Scene 1: Mantua. A magnificent hall in the ducal palace. Doors at the back open into other rooms, splendidly lit up. A crowd of lords and ladies in grand costumes are seen walking about in the rear rooms; page boys come and go. The festivities are at their height. Music is heard from offstage. The Duke and Borsa enter from a door in the back.
At a ball in his palace, the Duke sings of a life of pleasure with as many women as possible, and mentions that he particularly enjoys cuckolding his courtiers: "Questa o quella" ("This woman or that"). He mentions to Borsa that he has seen an unknown beauty in church and desires to possess her, but he also wishes to seduce the Countess of Ceprano. Rigoletto, the Duke's hunchbacked court jester, mocks the husbands of the ladies to whom the Duke is paying attention, including the Count Ceprano, and advises the Duke to get rid of him by prison or death. The Duke laughs indulgently, but Ceprano is not amused. Marullo, one of the guests at the ball, informs the courtiers that Rigoletto has a "lover", which astonishes them. (Marullo is not aware that the "lover" is actually Rigoletto's daughter.) The courtiers, at Ceprano's suggestion, resolve to take vengeance on Rigoletto for making fun of them. The festivities are interrupted by the arrival of the elderly Count Monterone, whose daughter the Duke had seduced. Rigoletto provokes him further by making fun of his helplessness to avenge his daughter's honor. Monterone confronts the Duke, and is immediately arrested by the Duke's guards. Before being led off to prison, Monterone curses both the Duke for the attack on his daughter and Rigoletto for having mocked his righteous anger. The curse terrifies Rigoletto, who believes the popular superstition that an old man's curse has real power.
Scene 2: The end of a dead-end street. On the left, a house of discreet appearance with one small courtyard surrounded by walls. In the yard there is one tall tree and a marble seat; in the wall, a door that leads to the street; above the wall, a terrace supported by arches. The second floor door opens on to the said terrace, which can also be reached by a staircase in front. To the right of the street is the very high wall of the garden and a side of the Ceprano palace. It is night.
Preoccupied with the old man's curse, Rigoletto approaches the house where he is concealing his daughter from the world and is accosted by the hit-man Sparafucile, who walks up to him and offers his services. Rigoletto declines for the moment, but leaves open the possibility of hiring Sparafucile later, should the need arise. Sparafucile wanders off, after repeating his own name a few times. Rigoletto contemplates the similarities between the two of them: "Pari siamo!" ("We are alike!"); Sparafucile kills men with his sword, and Rigoletto uses "a tongue of malice" to stab his victims. Rigoletto opens a door in the wall and embraces his daughter Gilda. They greet each other warmly: "Figlia!" "Mio padre!" ("Daughter!" "My father!"). Rigoletto has been concealing his daughter from the Duke and the rest of the city, and she does not know her father's occupation. Since he has forbidden her to appear in public, she has been nowhere except to church and does not even know her own father's name.
When Rigoletto has gone, the Duke appears and overhears Gilda confess to her nurse Giovanna that she feels guilty for not having told her father about a young man she had met at the church. She says that she fell in love with him, but that she would love him even more if he were a student and poor. As she declares her love, the Duke enters, overjoyed. Gilda, alarmed, calls for Giovanna, unaware that the Duke had sent her away. Pretending to be a student, the Duke convinces Gilda of his love: "È il sol dell'anima" ("Love is the sunshine of the soul"). When she asks for his name, he hesitantly calls himself Gualtier Maldè. Hearing sounds and fearing that her father has returned, Gilda sends the Duke away after they quickly trade vows of love: "Addio, addio" ("Farewell, farewell"). Alone, Gilda meditates on her love for the Duke, whom she believes is a student: "Gualtier Maldè!... Caro nome che il mio cor" ("Dearest name").
Later, Rigoletto returns: "Riedo!... perché?" ("I've returned!... why?"), while the hostile courtiers outside the walled garden (believing Gilda to be the jester's mistress, unaware she is his daughter) get ready to abduct the helpless girl. They tell Rigoletto that they are actually abducting the Countess Ceprano. He sees that they are masked and asks for a mask for himself; while they are tying the mask onto his face, they also blindfold him. Blindfolded and deceived, he holds the ladder steady while they climb up to Gilda's room: Chorus: "Zitti, zitti" ("Softly, softly"). With her father's unknowing assistance Gilda is carried away by the courtiers. Left alone, Rigoletto removes his mask and blindfold, and realizes that it was in fact Gilda who was carried away. He collapses in despair, remembering the old man's curse.
Act 2
A room in the ducal palace. There are doors on both sides as well as a larger one at the far end by the sides of which hang full length portraits of the Duke and his wife. There is one high-backed chair at a table covered with velvet and other furnishings.
The Duke is concerned that Gilda has disappeared: "Ella mi fu rapita!" ("She was stolen from me!") and "Parmi veder le lagrime" ("I seem to see tears"). The courtiers then enter and inform him that they have captured Rigoletto's mistress: Chorus: "Scorrendo uniti" ("We went together at nightfall"). By their description, he recognizes it to be Gilda and rushes off to the room where she is held: "Possente amor mi chiama" ("Mighty love beckons me"). Rigoletto enters singing and feigning nonchalance, but also looking anxiously for any trace of Gilda, whom he fears may have fallen into the hands of the Duke. The courtiers pretend not to notice his anxiety, but quietly laugh at him with each other. A page boy arrives with a message from the Duke's wife - the Duchess wishes to speak to her husband - but the courtiers reply suggestively that the Duke cannot be disturbed at the moment. Rigoletto realizes this must mean that Gilda is with the Duke. To the courtiers' surprise, he reveals that Gilda is his daughter. He first demands, then tearfully pleads with the courtiers to return her to him: "Cortigiani, vil razza dannata" ("Accursed race of courtiers"). Rigoletto attempts to run into the room in which Gilda is being held, but the courtiers block his way. After a time, Gilda enters, and Rigoletto orders the courtiers to leave him alone with her. The courtiers leave the room, believing Rigoletto has gone mad. Gilda describes to her father what has happened to her in the palace: "Tutte le feste al tempio" ("On all the holy days") and he attempts to console her. Monterone is led across the room on the way to prison and pauses in front of the portrait of the Duke to regret that his curse on the libertine has had no effect. As the guards lead Monterone away, Rigoletto mutters that the old man is mistaken; he, Rigoletto, the dishonored buffoon, shall make thunder and lightning rain from heaven onto the offender's head. He repeats this vow as Gilda pleads for mercy for her lover the Duke: Duet:"Sì! Vendetta, tremenda vendetta!" ("Yes! Revenge, terrible revenge!").
Act 3
The right bank of the river Mincio. On the left is a two-story house, half ruined. Through a large arch on the ground floor a rustic tavern can be seen as well as a rough stone staircase that leads to an attic room with a small bed which is in full view as there are no shutters. In the wall downstairs that faces the street is a door that opens to the inside. The wall is so full of holes and cracks that everything that happens inside is easily seen from the exterior. At the back of the stage are deserted areas by the river which flows behind a parapet that has half collapsed into ruins. Beyond the river is Mantua. It is night. Gilda and Rigoletto, both uneasy, are standing in the road; Sparafucile is seated at a table in the tavern.
A portion of Sparafucile's house is seen, with two rooms open to the view of the audience. Rigoletto and Gilda arrive outside. The Duke's voice can be heard from inside, singing "La donna è mobile" ("Woman is fickle"). Sparafucile's sister, Maddalena, has lured him to the house. Rigoletto and Gilda listen from outside as the Duke flirts with Maddalena. Gilda laments that the Duke is unfaithful; Rigoletto assures her that he is arranging revenge: "Bella figlia dell’amore" ("Beautiful daughter of love").
Rigoletto orders Gilda to put on a man's clothes to prepare to leave for Verona and tells her that he plans to follow later. After she leaves, he completes his bargain with the assassin, who is ready to murder his guest for 20 scudi. Rigoletto then withdraws.
With falling darkness, a thunderstorm approaches and the Duke decides to spend the rest of the night in the house. Sparafucile directs him to the upstairs sleeping quarters, resolving to kill him in his sleep.
Gilda, who still loves the Duke despite knowing him to be unfaithful, returns dressed as a man and stands outside the house. Maddalena, who is smitten with the Duke, begs Sparafucile to spare his life: "È amabile invero cotal giovinotto/ Ah, più non ragiono!...". Sparafucile reluctantly promises her that if by midnight another victim can be found, he will kill the other instead of the Duke. Gilda, overhearing this exchange, resolves to sacrifice herself for the Duke, and enters the house: "Trio: Se pria ch’abbia il mezzo la notte toccato". Sparafucile stabs her and she collapses, mortally wounded.
At midnight, when Rigoletto arrives with money, he receives a corpse wrapped in a sack, and rejoices in his triumph. Weighting it with stones, he is about to cast the sack into the river when he hears the voice of the Duke, sleepily singing a reprise of his "La donna è mobile" aria. Bewildered, Rigoletto opens the sack and, to his despair, discovers his dying daughter. For a moment, she revives and declares she is glad to die for her beloved: "V'ho ingannato" ("Father, I deceived you"). She dies in his arms. Rigoletto cries out in horror: "La maledizione!" ("The curse!")

Backstory: The Egyptians have captured and enslaved Aida, an Ethiopian princess. An Egyptian military commander, Radamès, struggles to choose between his love for her and his loyalty to the King of Egypt. To complicate the story further, the King's daughter Amneris is in love with Radamès, although he does not return her feelings.
Act 1
Scene 1: A hall in the King's palace; through the rear gate the pyramids and temples of Memphis are visible
Ramfis, the high priest of Egypt, tells Radamès, the young warrior, that war with the Ethiopians seems inevitable, and Radamès hopes that he will be chosen as the Egyptian commander (Ramfis, Radamès: "Sì, corre voce l'Etiope ardisca" / Yes, it is rumored that Ethiopia dares once again to threaten our power).
Radamès dreams both of gaining victory on the battlefield and of Aida, an Ethiopian slave, with whom he is secretly in love (Radamès: "Se quel guerrier io fossi! ... Celeste Aida" / Heavenly Aida). Aida, who is also secretly in love with Radamès, is the captured daughter of the Ethiopian King Amonasro, but her Egyptian captors are unaware of her true identity. Her father has invaded Egypt to deliver her from servitude.
Amneris, the daughter of the Egyptian King, enters the hall. She too loves Radamès, but fears that his heart belongs to someone else (Radamès, Amneris: "Quale insolita gioia nel tuo sguardo" / In your looks I trace a joy unwonted).
Aida appears and, when Radamès sees her, Amneris notices that he looks disturbed. She suspects that Aida could be her rival, but is able to hide her jealousy and approach Aida (Amneris, Aida, Radamès: "Vieni, o diletta, appressati" / Come, O delight, come closer).
The King enters, along with the High Priest, Ramfis, and the whole palace court. A messenger announces that the Ethiopians, led by King Amonasro, are marching towards Thebes. The King declares war and proclaims that Radamès is the man chosen by the goddess Isis to be the leader of the army (The King, Messenger, Radamès, Aida, Amneris, Ramfis, chorus: "Alta cagion v'aduna .. Guerra, guerra, guerra!" / Oh fate o'er Egypt looming .. War, war, war!). Upon receiving this mandate from the King, Radamès proceeds to the temple of Vulcan to take up the sacred arms (The King, Radamès, Aida, Amneris, chorus: "Su! del Nilo al sacro lido" .. (reprise) "Guerra, guerra guerra!" / On! Of Nilus' sacred river, guard the shores .. (reprise) War, war, war!).
Alone in the hall, Aida feels torn between her love for her father, her country, and Radamès (Aida: "Ritorna vincitor" / Return a conqueror).
Scene 2: Inside the Temple of Vulcan
Solemn ceremonies and dances by the priestesses take place (High Priestess, chorus, Radamès: "Possente Ftha ... Tu che dal nulla" / O mighty Ptah). This is followed by the installation of Radamès to the office of commander-in-chief (High Priestess, chorus, Ramfis, Radamès: "Immenso Ftha .. Mortal, diletto ai Numi" / O mighty one, guard and protect!). All present in the temple pray fervently for the victory of Egypt and protection for their warriors ("Nume, custode e vindice"/ Hear us, O guardian deity).
Act 2
Scene 1: The chamber of Amneris
Dances and music to celebrate Radamès' victory take place (Chorus, Amneris: "Chi mai fra gli inni e i plausi" / Our songs his glory praising). However, Amneris is still in doubt about Radamès' love and wonders whether Aida is in love with him. She tries to forget her doubt, entertaining her worried heart with the dance of Moorish slaves (Chorus, Amneris: "Vieni: sul crin ti piovano" / Come bind your flowing tresses).
When Aida enters the chamber, Amneris asks everyone to leave. By falsely telling Aida that Radamès has died in the battle, she tricks her into professing her love for him. In grief, and shocked by the news, Aida confesses that her heart belongs to Radamès eternally (Amneris, Aida: "Fu la sorte dell'armi a' tuoi funesta" / The battle's outcome was cruel for your people).
This confession fires Amneris with rage, and she plans on taking revenge on Aida. Ignoring Aida's pleadings (Amneris, Aida, chorus: "Su! del Nilo al sacro lido" / Up! at the sacred shores of the Nile), Amneris leaves her alone in the chamber.
Scene 2: The grand gate of the city of Thebes
Radamès returns victorious and the troops march into the city (Chorus, Ramfis: "Gloria all'Egitto, ad Iside" / Glory to Egypt, [and] to Isis!).
The Egyptian king decrees that on this day the triumphant Radamès may have anything he wishes. The Ethiopian captives are led onstage in chains, Amonasro among them. Aida immediately rushes to her father, who whispers to her to conceal his true identity as King of Ethiopia from the Egyptians. Amonasro deceptively proclaims to the Egyptians that the Ethiopian king (referring to himself) has been slain in battle. Aida, Amonasro, and the captured Ethiopians plead with the Egyptian King for mercy, but Ramfis and the Egyptian priests call for their death (Aida, Amneris, Radamès, The King, Amonasro, chorus: "Che veggo! .. Egli? .. Mio padre! .. Anch'io pugnai .. Struggi, o Re, queste ciurme feroci" / What do I see?.. Is it he? My father? .. Destroy, O King, these ferocious creatures).
Claiming the reward promised by the King of Egypt, Radamès pleads with him to spare the lives of the prisoners and to set them free. The King grants Radamès' wish, and declares that he (Radamès) will be his (the King's) successor and will marry the King's daughter (Amneris). (Aida, Amneris, Radamès, Ramfis, The King, Amonasro, chorus: "O Re: pei sacri Numi! .. Gloria all'Egitto" / O King, by the sacred gods ... Glory to Egypt!). At Ramfis' suggestion to the King, Aida and Amonasro remain as hostages to ensure that the Ethiopians do not avenge their defeat.
Act 3
On the banks of the Nile, near the Temple of Isis
Prayers are said (Chorus, High Priestess, Ramfis, Amneris: "O tu che sei d'Osiride" / O thou who to Osiris art) on the eve of Amneris and Radamès' wedding in the Temple of Isis. Outside, Aida waits to meet with Radamès as they had planned (Aida: "Qui Radamès verra .. O patria mia" / Oh, my dear country!).
Amonasro appears and orders Aida to find out the location of the Egyptian army from Radamès. Aida, torn between her love for Radamès and her loyalty to her native land and to her father, reluctantly agrees. (Aida, Amonasro: "Ciel, mio padre! .. Rivedrai le foreste imbalsamate" / Once again shalt thou gaze). When Radamès arrives, Amonasro hides behind a rock and listens to their conversation.
Radamès affirms that he will marry Aida ("Pur ti riveggo, mia dolce Aida .. Nel fiero anelito"; "Fuggiam gli ardori inospiti .. Là, tra foreste vergini" / I see you again, my sweet Aida!), and Aida convinces him to flee to the desert with her.
In order to make their escape easier, Radamès proposes that they use a safe route without any fear of discovery and reveals the location where his army has chosen to attack. Upon hearing this, Amonasro comes out of hiding and reveals his identity. Radamès realizes, to his extreme dismay, that he has unwittingly revealed a crucial military secret to the enemy. At the same time, Amneris and Ramfis leave the temple and, seeing Radamès in conference with the enemy, call for the imperial guards. Amonasro draws a dagger, intending to kill Amneris and Ramfis before the guards can hear them, but Radamès disarms him, quickly orders him to flee with Aida, and surrenders himself to the imperial guards as Aida and Amonasro run off. The guards arrest him as a traitor.
Act 4
Scene 1: A hall in the Temple of Justice. To one side is the door leading to Radamès' prison cell
Amneris desires to save Radamès ("L'aborrita rivale a me sfuggia" / My hated rival has escaped me). She calls for the guard to bring him to her.
She asks Radamès to deny the accusations, but Radamès, who does not wish to live without Aida, refuses. He is relieved to know Aida is still alive and hopes she has reached her own country (Amneris, Radamès: "Già i Sacerdoti adunansi" / Already the priests are assembling).
Offstage, Ramfis recites the charges against Radamès and calls on him to defend himself, but he stands mute, and is condemned to death as a traitor. Amneris, who remains onstage, protests that he Radamès is innocent, and pleads with the priests to show mercy. The priests sentence him to be buried alive; Amneris weeps and curses the priests as he is taken away (Judgment scene, Amneris, Ramfis, and chorus: "Ahimè! .. morir mi sento .. Radamès, e deciso il tuo fato" / Alas .. I feel death .. Radamès, your fate is decided).
Scene 2: The lower portion of the stage shows the vault in the Temple of Vulcan; the upper portion represents the temple itself
Radamès has been taken into the lower floor of the temple and sealed up in a dark vault, where he thinks that he is alone. As he hopes that Aida is in a safer place, he hears a sigh and then sees Aida. She has hidden herself in the vault in order to die with Radamès (Radamès and Aida: "La fatal pietra sovra me si chiuse." / The fatal stone now closes over me). They accept their terrible fate (Radamès: "Morir! Si pura e bella" / To die! So pure and lovely!) and bid farewell to Earth and its sorrows. Above the vault in the temple of Vulcan, Amneris weeps and prays to the goddess Isis. In the vault below, Aida dies in Radamès' arms as the priests, offstage, pray to the god Ftha. (Chorus, Aida, Radamès, Amneris: "Immenso Ftha" / Almighty Ptah).

Place: Stockholm, Sweden or Boston, Massachusetts
Time: March 1792 in Sweden or the end of the 17th century in Boston
Act 1
Scene 1: A public audience at Riccardo's palace, attended by his supporters, but also by his enemies who hope for his demise.
Riccardo (Gustavo) reviews the list of guests who will attend an upcoming masked ball. He is elated to see the name of the woman he loves on the list – Amelia, the wife of his friend and advisor, Renato (Count Anckarström). (Aria: La rivedrò nell'estasi / "There I will be in ecstasy to see her again"). When Renato arrives, he tries to warn Riccardo about the growing conspiracy against him (aria: Alla vita che t'arride / "Your life, so full of joy and hope"), but Riccardo refuses to listen to his words.
Next, Riccardo is presented with a complaint against a fortune-teller named Ulrica (Madame Arvidson), accused of witchcraft. A magistrate calls for her banishment, but Oscar the page defends her (Aria: Volta la terrea / "Turning her eyes from the earth"). Riccardo resolves to investigate for himself and tells the members of the court to disguise themselves and to meet him at Ulrica's lodging later that day.
Scene 2: At Ulrica's dwelling
Ulrica summons her magical powers: Re dell'abisso, affrettati / "King of the abyss, make haste". Disguised as a fisherman, Riccardo arrives before the others. He makes the fortune of a sailor named Silvano come true by spiriting a document of promotion into his pouch, convincing the crowd of the truth of Ulrica's powers. When he realizes that Amelia is coming to see Ulrica, he hides and watches. Alone with Ulrica, Amelia confesses that she is tormented by her love for Riccardo, and asks for a means to bring peace to her heart. Ulrica tells her to gather a certain herb with magical powers; Riccardo resolves to be there when she does so. Amelia leaves.
Now Riccardo presents himself again, along with all of the courtiers, and asks to have his fortune told. (Aria: Di' tu se fedele / "Tell me if the sea awaits me faithfully"). Ulrica reveals that he will be killed by the next man who shakes his hand. He laughingly dismisses her prophecy and offers his hand to the courtiers, who refuse to take it. Renato arrives and shakes Riccardo's hand in greeting. Riccardo's true identity is now revealed and he is acclaimed by the people.
Act 2
On the outskirts of the town, at the gallows-place. Midnight
Amelia, conquering her fears, has come here alone to pick the herb of which Ulrica told her (Aria: Ma dall'arido stelo divulsa / "But when I have plucked the herb"). She is surprised by Riccardo, who has come to meet her, and the two finally declare their love for each other.
Unexpectedly, Renato arrives, and Amelia covers her face with her veil before he can recognize her. Renato explains to Riccardo that the conspirators are pursuing him, and his life is in danger. Riccardo leaves, making Renato promise to escort the veiled woman safely back to town, not asking her identity. When the conspirators arrive, they confront Renato; in the struggle, Amelia's veil drops. Renato assumes that Amelia and Riccardo have been involved in an adulterous love affair. He asks the two leaders of the conspiracy, Samuel and Tom, to meet him the next day.
Act 3
Scene 1: Renato's house
Renato has resolved to kill Amelia for the dishonor she has brought on him. She protests her innocence and begs to see her son one last time. (Aria: Morrò, ma prima in grazia / "I will die, but first, a kindness"). Renato relents, and declares that it is Riccardo, not Amelia, who deserves to die (Aria: Eri tu che macchiavi quell'anima / "You were the one who stained her soul").
Samuel (Count Ribbing) and Tom (Count Horn) arrive, and Renato asks to join their plot, pledging the life of his son as proof of his sincerity. They agree to draw lots to decide who will kill Riccardo. Amelia is forced to draw the winning name – Renato.
Oscar, the page, arrives with invitations to the masked ball; Samuel, Tom and Renato agree that this is where the assassination will take place.
Scene 2: The ball
Riccardo, torn between love and duty, has resolved to renounce his love for Amelia and send her and Renato back to England (Aria: Ma se m'è forza perderti / "But if I am forced to lose her").
At the ball, Renato tries to learn from Oscar what costume Riccardo is wearing. Oscar at first refuses to tell (Aria: Saper vorreste / "You want to know"), but he finally answers: a black cloak and a red ribbon. Riccardo manages to identify Amelia and tells her of the decision he has made. As they say goodbye, Renato stabs Riccardo. The wounded Riccardo discloses that though he loved Amelia, she never broke her marriage vows. He pardons all the conspirators, bidding farewell to his friends and his country as he dies.

Place: A 19th-century Sicilian village
Time: Easter morning
Before the action takes place, the young villager Turiddu had returned from military service to find that his fiancée Lola had married the carter Alfio while Turiddu was away. In revenge, Turiddu had seduced Santuzza, a young woman in the village. As the opera begins, Lola, overcome by her jealousy of Santuzza, has begun an adulterous affair with Turiddu.
The main square of the village
Offstage, Turiddu is heard singing a siciliana, "O Lola c'hai di latti la cammisa" ("O Lola! like the snow, pure in thy whiteness!"). To one side is the church; to the other is Lucia's wine shop and the house where she lives with her son, Turiddu. The villagers move about the square, singing of the beautiful spring day, "Gli aranci olezzano sui verdi margini" ("The air is sweet with orange blossoms") and a hymn to the Blessed Virgin Mary. Some villagers enter the church, and others wander off still singing.
Santuzza, having slept with Turiddu and suspecting that he has betrayed her for Lola, is distraught and approaches Lucia as she comes out of her house. Santuzza asks for Turiddu, but Lucia replies that he has gone to another town to fetch some wine. Santuzza tells her that he was seen during the night in the village. Lucia asks her inside to talk, but just at that moment Alfio arrives on his wagon, accompanied by the villagers. He praises the joys of a teamster's life and the beauty of Lola his bride. Alfio asks Lucia for some of her fine old wine. She tells him it has run out and Turiddu has gone away to buy more. Alfio replies that he had seen Turiddu early that morning near his cottage. Lucia starts to express surprise, but Santuzza stops her.
Alfio leaves. The choir inside the church is heard singing the Regina Coeli. Outside, the villagers sing an Easter Hymn, "Inneggiamo, il Signor non è morto" ("We rejoice that our Saviour is living!") joined by Santuzza. The villagers enter the church, while Santuzza and Lucia remain outside. Lucia asks Santuzza why she signalled her to remain silent when Alfio said that he had seen Turiddu that morning. Santuzza exclaims, "Voi lo sapete" ("You well know") and tells Lucia the story of her seduction by Turiddu and his affair with Lola. Lucia pities Santuzza, who feels dishonored, having been seduced by Turiddu only to be abandoned by him for his old flame, Lola. Santuzza feels she cannot enter the church, but begs Lucia to go inside herself and pray for Santuzza who stays behind to try to plead with Turiddu to leave Lola and return to her.
Turiddu arrives. Santuzza upbraids him for pretending to have gone away, when he was actually seeing Lola. Lola enters the square singing. She mocks Santuzza and goes inside the church. Turiddu turns to follow Lola, but Santuzza begs him to stay. Turiddu pushes her away. She clings to him. He loosens her hands, throws her to the ground, and enters the church. Alfio arrives looking for Lola. Santuzza tells him that his wife has betrayed him with Turiddu. Alfio swears to take vendetta (revenge) which causes Santuzza to repent for having disclosed the affair and begs Alfio to stop to no avail.
The square is empty as the orchestra plays the famous Intermezzo.
The villagers come out of the church. Turiddu is in high spirits because he is with Lola and Santuzza appears to have gone. He invites his friends to his mother’s wine shop where he sings a drinking song, "Viva, il vino spumeggiante" ("Hail to the bubbling wine!"). Alfio joins them. Turiddu offers him wine, but he refuses it. All understand that trouble is in the air. The women leave, taking Lola with them. In a brief exchange of words, Alfio challenges Turiddu to a duel. Following Sicilian custom, the two men embrace, and Turiddu, in a token of acceptance, bites Alfio’s ear, drawing blood which signifies a fight to the death. Alfio leaves and Turiddu calls Lucia back. He tells her that he is going outside to get some air and asks that she be a kindly mother to Santuzza if he should not return: "Un bacio, mamma! Un altro bacio!—Addio!" ("One kiss, mother! One more kiss! – Farewell!").
Turiddu rushes out. Lucia, weeping, wanders aimlessly around outside her house. Santuzza approaches and throws her arms around her. The villagers start to crowd around. Voices are heard in the distance and a woman cries, "They have murdered Turiddu!" Santuzza faints and Lucia collapses in the arms of the women villagers.
