The Pirates of Penzance; or, The Slave of Duty is a comic operetta by W. S. Gilbert and Arthur Sullivan, a two-act work of Victorian musical theatre set on the Cornish coast and in a ruined chapel nearby. Its Dramatis Personae run from Major-General Stanley and the Pirate King down through his Lieutenant Samuel, the apprentice Frederic, a Sergeant of Police, the General’s many daughters (Mabel foremost among them), and Ruth, the pirate maid of all work, all supported by choruses of pirates, police, and daughters. The piece turns on a single absurd hinge—a birthday that falls on the twenty-ninth of February—and spins out of it a comedy about duty, apprenticeship, and the letter of the bond.
A Nurserymaid’s Mistake and a Pirate’s Release
The first act opens on a rocky Cornish shore with a schooner at anchor, where the pirates drink and play cards while Frederic sits despondent and Ruth kneels at his feet. The chorus celebrates his release from his indentures, and the Pirate King tells him he now ranks as a full member of the band. Frederic announces that he is leaving them forever: bound by duty under his indentures, he calls himself “the slave of duty.” The whole entanglement, Ruth explains, began with her own deafness—she was his nurserymaid and mistook the word “pilot” for “pirate,” apprenticing him to a pirate instead of a pilot, and becoming a piratical maid-of-all-work herself. Frederic pardons her.
His obligation, he says, ceases that afternoon. Individually he loves the pirates; collectively he detests them, and once free he will devote himself to their extermination. The King advises him to act on conscience. Samuel observes that piracy does not pay, and Frederic explains why: the pirates are too tender-hearted, never attacking weaker parties, being thrashed by stronger ones, and never molesting orphans—so every captive claims to be one.
Ruth asks what will become of her, and Frederic doubts her beauty, since she is the only woman he has seen since the age of eight. Samuel finds “the remains of a fine woman about Ruth,” so Frederic leaves her behind; the King returns her, and she exits. The King sings that it is better to live and die a Pirate King than play a sanctimonious part, claiming that kings must do dirtier work than he. Ruth returns to plead that she accompany Frederic; he objects to her age—forty-seven, against a wife of seventeen—and she insists she is a fine woman. He accepts her on that condition until girls’ voices are heard. Seeing beautiful maidens, he denounces Ruth as false and old, and she exits in despair while Frederic hides in a cave, ashamed of his costume.
The General’s daughters enter singing of climbing over rocky mountain, and Kate, Edith, and Isabel remark on the picturesque spot and their absent papa. They prepare to paddle barefoot; Frederic stops them and declares himself a pirate, then renounces his profession and begs their aid. Mabel alone responds with pity, singing “Poor wandering one.” Edith proposes a compromise—they will shut their eyes and talk about the weather—which the girls do in a chattering chorus.
Mabel, the Major-General, and the Orphan Plea
Mabel sings of a maiden waking from dreams of homely duty to exceeding beauty and gladness; Frederic echoes her, while the girls chatter pianissimo about the blue sky. Frederic solos on whether a pirate ever rolled his soul in guilty dreaming and woke to find it beaming with peace and virtue, and the ensemble combines their lines. He then warns the young ladies to leave while the coast is clear, since men who stick at no offences will soon arrive. He and Mabel retire—and the warning comes too late. The pirates enter stealthily, form a semi-circle behind the girls, and each seizes one: the King takes Edith and Isabel, Samuel takes Kate. The girls cry “Too late!” and the pirates laugh, singing of a first-rate opportunity to get married with impunity and indulge in domesticity, while the ladies lament their missed escape. Both sides sing that they shall quickly be “parsonified” and “conjugally matrimonified” by a doctor of divinity residing in the vicinity.
Mabel comes forward with “Hold, monsters!” and warns that they are Wards in Chancery and their father is a Major-General. Samuel, cowed, says they had better pause; the girls confirm it; and the Major-General, having entered unnoticed on a rock, confirms that he is a Major-General, to general hurrahs. He sings the famous song declaring himself the very model of a modern Major-General: information vegetable, animal, and mineral; the kings of England and historical fights from Marathon to Waterloo; mathematics, equations, the binomial theorem, the square of the hypotenuse; integral and differential calculus and animalculous beings. He knows mythic history, answers acrostics, has a taste for paradox, quotes in elegiacs the crimes of Heliogabalus, can floor “peculiarities parabolus” in conics, distinguish Raphaels from Gerard Dows and Zoffanies, knows the croaking chorus from Aristophanes’ “Frogs,” can hum a fugue and whistle airs from “Pinafore.” He can write a washing bill in Babylonic cuneiform and detail Caractacus’s uniform. He wishes he knew “mamelon” and “ravelin,” could tell a mauser rifle from a javelin, were wary of sorties and surprises, knew commissariat and modern gunnery and more tactics than a novice in a nunnery; with a smattering of elemental strategy, none better has sat a gee—though his military knowledge, plucky and adventury, is only brought down to the beginning of the century.
Asked what is going on, Kate begins “Oh, papa—we—” and Samuel explains in two words that they propose to marry his daughters. The General objects; the girls protest it is against their wills; he asks about their picturesque uniform and learns they are “all single gentlemen” and nothing else. Edith reveals they are the famous Pirates of Penzance, of whom the General has often heard. Mabel notes that Frederic was a pirate once but is out of his indentures today and means to lead a blameless life. The General objects to pirates as sons-in-law; the King objects to Major-Generals as fathers-in-law but waives the point. The General, aside, has an idea: he asks whether they would rob him of the sole remaining props of his old age and leave him unfriended, unprotected, and alone—which, the King agrees, is the idea. He asks whether they have ever known what it is to be an orphan. The pirates are disgusted (“Here we are again!”); the King says “Often!” Confusion follows over “orphan” versus “often”—the General meant a person who has lost his parents, not “frequently”; the King concedes he meant frequently, then says he said it only once; the General, irritated, says exactly—often, frequently, only once.
The General recites “Oh, men of dark and dismal fate,” urging them to forego their cruel employ and pity his lonely state: he is an orphan boy. The pirates echo “An orphan boy!” and “How sad.” He sings that these children are all he can call his own, and that taking them away leaves him indeed alone; he begs them, if they can feel pity, to leave his sole remaining joy, noting the girls kneel at their feet. The pirates sob “Poor fellow!” In ensemble, the girls note he tells a terrible story that will diminish his glory, though the pirates would have taken his daughters over the billowy waters; the General admits he tells a terrible story but says it doesn’t diminish his glory, since they would have taken his daughters had he not, in elegant diction, indulged in an innocent fiction—not the same category as a regular terrible story. The pirates, aside, say that if he tells a terrible story he shall die a gory death, one of the cruellest slaughters known in these waters; it is easy in elegant diction to call it an innocent fiction, but it comes in the same category as a regular terrible story. The King sings that although their dark career sometimes involves stealing, they think they are—
The Leap-Year Paradox and the Police
The passage opens with the Pirate King and the pirates celebrating “a most ingenious paradox” with repeated laughter. The King explains that they knew Frederic’s taste for “curious quips” and “cranks and contradictions queer,” and that they risked “life and limb” to tell “our boy” the joke, believing he would enjoy it. Frederic asks, “That paradox?” and the King confirms it.
The King then explains, in song, that “some person in authority”—possibly “the Astronomer Royal”—decided that although February usually has twenty-eight days, “one year in every four his days shall be reckoned as nine-and-twenty.” Through “some singular coincidence” (perhaps owing to “an ill-natured fairy”), Frederic was born in leap-year on the twenty-ninth of February. By “a simple arithmetical process,” though Frederic has lived twenty-one years, by birthdays he is “only five and a little bit over.” Frederic counts on his fingers, agrees, and is amused; all sing of the paradox that mocks common sense—twenty-one years alive, yet “a little boy of five.” Ruth and the King collapse with laughter. Frederic calls it “most curious—most absurdly whimsical,” noting “Five and a quarter!”
Ruth says he will be glad he spared them, since otherwise he would have killed two comrades. The King warns Frederic he doesn’t appreciate “the delicacy of your position”: Frederic was apprenticed until his twenty-first birthday, producing a document, and by birthdays he is “only five and a quarter.” Frederic protests; the King says they merely remind him and leave the rest to his “sense of duty.” Frederic implores them not to insist on “the letter of your bond” when “the cup of happiness is at my lips”; Ruth and the King insist on nothing, only pointing out his duty. Frederic yields: he abhors their “infamous calling” but “duty is before all.” The King welcomes him back.
Frederic then suddenly cries “Oh, horror!” and, as one of the band, confesses that General Stanley, father of his beloved Mabel, “escaped from you on the plea that he was an orphan”—and “is no orphan,” indeed “never was one.” The King vows “swift and terrible” revenge, resolving to collect the band and attack Tremorden Castle that very night, despite Frederic’s attempt to object. All sing of vengeance; Frederic finds his duty hard. They debate whether the General’s daughters will “welter in sorrow,” and resolve the traitor dies “to-night… or early to-morrow.”
Mabel enters; the King and Ruth exit. She tells Frederic all is prepared and his crew awaits, and marvels that he weeps. He explains his bond to serve until his twenty-first birthday, which, born in leap-year, he won’t reach till 1940. Mabel calls it “Catastrophe appalling.” In duet she urges him to stay, arguing the pirates have “no legal claim”; he insists “stern Duty calls.” In ballad they lament; Frederic declares he will return in 1940 to claim her, and Mabel swears by “all the Stanleys dead and gone” to be true. An ensemble praises love and truth. Frederic leaps out the window; Mabel steels herself and summons the Police.
The Sergeant and Police enter in single file, singing of being “timidly inclined” yet appearing “insensible to fear.” Mabel tells the Sergeant that Frederic, who was to lead them “to death and glory,” has rejoined his old associates. The Police say he acted shamefully; Mabel corrects them—he acted nobly, his “heroic sacrifice to his sense of duty” endearing him tenfold; she will do her duty and exits. The Police find it “perplexing” but resolve to capture the pirates alone, lamenting being agents depriving fellow-creatures of liberty—”we should have thought of that before we joined the force.” The Sergeant sings that a policeman’s lot is not a happy one.
The Night Attack and the Queen’s Name
Pirate chorus is heard approaching; the Sergeant notes they come “on the manor poaching” and the Police hide. The Pirates enter cautiously; Samuel distributes burglarious tools—crowbar, centrebit, life preserver, matches, dark lantern, file, skeleton keys. The King, Frederic, and Ruth enter; Frederic sees a light—the Major-General comes—and all hide. General Stanley enters in dressing-gown with a light, singing of anguish and falsehood unatoned, thinking he heard a noise, then deciding it was “the sighing of the breeze,” and sings a ballad of the breeze, brook, and poplars. His daughters enter in white peignoirs and night-caps with candles, wondering why their methodical father, who goes to bed at half-past ten, is up so incompletely dressed. The King, Samuel, and Frederic enter and seize the General. The girls cry “The pirates!” Mabel calls for Frederic to save them; he says he would but is “not able,” and the Pirates confirm he tells the truth. The King sings of revenge and bids General Stanley prepare for death. The girls plead; the Police spring up, revealed, and a struggle ensues in which the Police are overcome and fall prostrate. Chorus notes no pirate band will stand at the Central Criminal Court. The Sergeant claims a stronger claim—charging them to yield “in Queen Victoria’s name.” The Pirates kneel; the King says they yield because “we love our Queen.” The General orders them to the bar. Ruth enters, revealing they—
Duty, Paradox, and the Sense of an Ending
What holds the operetta together is the collision between two kinds of obligation. Frederic is a man of absolute conscience: he loves the pirates as individuals and loathes their trade, yet he will not break the letter of a bond he never chose, even when the bond has been rendered absurd by a calendar. Gilbert builds the comedy on that absurdity—the leap-year birthday that keeps a grown man legally five—and then refuses to let Frederic laugh it away. The “ingenious paradox” is funny to the pirates and devastating to the lovers, and the joke is precisely that duty, followed to the letter, produces monstrous results.
Around Frederic, the other figures each embody a softened or self-serving version of the same theme. The pirates are sentimentalists who claim tenderness as a virtue while plundering; the Major-General invents an orphan’s grief to save his daughters and then worries, in ensemble, about the difference between an innocent fiction and a regular terrible story; the Police fret about depriving fellow-creatures of liberty only after joining the force. Ruth’s deafness sets the whole plot in motion, a small domestic error swelling into twenty-one years of piracy. Mabel’s constancy—her vow by “all the Stanleys dead and gone” to wait until 1940—matches Frederic’s rigor with her own.
The resolution arrives through an appeal not to law but to loyalty: the pirates kneel at the Sergeant’s charge “in Queen Victoria’s name” because, as the King says, “we love our Queen.” It is a characteristic Gilbert stroke—authority dissolved by affection, the fearsome band disarmed by sentiment rather than force—and it leaves the operetta poised between satire of duty and affection for the dutiful. Sullivan’s music carries the same double edge, giving the nonsense of the Major-General’s catalogue and the paradox song the full weight of operatic earnestness. The result is a work that mocks the slave of duty while making him, and the woman who waits for him, the most sympathetic figures on the stage.
