Plot Summary
Chapter 25 of Moby-Dick, titled "Postscript," serves as a brief addendum to the preceding chapter's defense of whaling's dignity. Ishmael opens by acknowledging that what follows is not a substantiated fact but rather a "not unreasonable surmise" that he feels compelled to share on behalf of his cause. He then turns his attention to the ceremonial anointing of kings and queens at their coronations, noting that even modern monarchs undergo this "curious process of seasoning." Ishmael observes that a king's head is "solemnly oiled at his coronation, even as a head of salad," and wonders humorously whether the purpose is to make "its interior run well, as they anoint machinery."
Having established the fact of royal anointing, Ishmael poses the central question: what kind of oil is used? He systematically eliminates olive oil, macassar oil, castor oil, bear's oil, train oil, and cod-liver oil, concluding triumphantly that it can only be sperm oil "in its unmanufactured, unpolluted state, the sweetest of all oils." He closes with a rousing direct address to the British people: "Think of that, ye loyal Britons! we whalemen supply your kings and queens with coronation stuff!"
Character Development
Ishmael continues to develop his persona as a passionate advocate for the whaling profession. In this chapter he reveals his self-awareness as a rhetorician, openly admitting that he is departing from strict evidence into the realm of speculation. This transparency gives his argument a disarming honesty even as he advances a claim he cannot fully prove. His voice shifts between that of a formal legal advocate, a satirical humorist, and a proud working-class spokesman challenging the aristocracy's pretensions.
Themes and Motifs
The chapter extends the motif of the dignity of labor, arguing that the whaling trade is so essential that even royalty depends on its products for their most sacred rituals. The theme of democratic leveling runs throughout: by connecting the common whaleman's labor to the coronation of kings, Ishmael collapses the hierarchy between working sailor and sovereign. The anointing motif also carries religious overtones, linking the secular act of coronation to biblical traditions of anointing with oil, and suggesting that whale oil is the holiest of substances.
Literary Devices
Melville employs rhetorical questions as the chapter's primary structural device, building suspense before the triumphant reveal that sperm oil must be the coronation oil. The chapter uses process of elimination as a logical strategy, listing and dismissing alternative oils in rapid succession. Satirical irony pervades the passage: the mock-serious tone of legal advocacy applied to hair oil creates comic deflation, while the grandiose conclusion elevates whalemen above royalty. The chapter's very title, "Postscript," functions as a metafictional device, drawing attention to the constructed nature of Ishmael's argument and his deliberate separation of fact from speculation.
