Byron announces he'll write plain, simple, moral verse — inside ottava rima, the most ornate stanza in English. Horace says the same thing straight: instruct or please or both. The difference is that Byron's claim is already the joke that disproves it. You cannot peel the irony from the sincerity. Horace you can.

"Plain—simple—short, and by no means inviting, / But with a moral to each error tack'd" — Byron. He tacks the moral on in a line that rhymes with "attack'd." Horace genuinely believes form follows judgment. Byron knows the form is the judgment. One is a treatise. The other is the treatise eating itself.

Lord Byron, “Don Juan: Canto V”

Pope and Tennyson both put moonlight on a building to show a watcher outside it. But Pope's moonbeam is a stage direction — it "tips with silver all the walls" so the poet can demonstrate he knows how to do this. The showing is the point. Tennyson's moon gleams "by fits." It won't hold still. It's not for him.

"The white chalk-quarry from the hill / Gleam'd to the flying moon by fits" — Tennyson. The light keeps breaking. Pope's moonbeam falls once, perfectly, and serves the architecture. Tennyson's is interrupted because the watcher is interrupted — by hope, by doubt, by the shadow crossing the blind. Desire makes the moon unreliable.

Alfred Lord Tennyson, “The Miller's Daughter”

Rochester and Herrick both know what fables are for. But Rochester's fable is a weapon — call the Plot a fable and you're damned for it, the word is an accusation. Herrick's fable is a shelter: "No cruell truths of Philomell... But Fables we'l relate." The fable protects the maids from the real story.

Same word, opposite operations. Rochester makes fable mean lie. Herrick makes fable mean mercy. The gap: whether fiction is what you retreat into or what you're convicted of. 1648 and 1683 are only thirty-five years apart but the word crossed the floor between them.

The peelability test in four lines. Coleridge tries to describe Donne and the description becomes Donne — the syntax knotted, the metaphors metallurgical, the couplet limping on purpose. He can't stand outside it. The critical poem catches the disease of its subject.

"Rhyme's sturdy cripple, fancy's maze and clue, / Wit's forge and fire-blast, meaning's press and screw." — Coleridge

Samuel Taylor Coleridge, “ON DONNE'S POETRY”

Hardy goes to the exact garden at the exact hour 110 years later and the ghost he finds asks him a question about the present. The poem is a machine for making the dead interrogate the living. Not the other way around. The séance runs backward.

"Truth like a bastard comes into the world / Never without ill-fame to him who gives her birth" — Milton, via Gibbon, via Hardy. Three dead men passing the same complaint forward. The line survives because the problem does.

Thomas Hardy, “Lausanne In Gibbon's Old Garden: 11–12 P.M.”

Arnold's caution is afraid of itself. It warns poets to feel pleasure in making — but the poem enacting that warning is the driest, most joyless quatrain imaginable. The pleasure is absent from the instruction to feel pleasure. The caution fails its own test and knows it.

"What poets feel not, when they make, / A pleasure in creating, / The world, in turn, will not take / Pleasure in contemplating." — Arnold

Matthew Arnold, “A Caution to Poets”

The body confesses before the voice does. Every question in this stanza already contains its answer — the shaking, the mud, the wet, the heartbeat. The speaker asks why as a way of saying I know. The interrogative is the accusation that cannot yet afford to be declarative.

"And why feel I thy heart a-thumping every time thou kissest me, / And thy breath as if hard to get?" — Hardy

Thomas Hardy, “A Sound in the Night (Woodsford Castle: 17–)”

The peelability test, turned upside down: what if the passage that resists separation isn't the better poem but the one that hasn't yet found the reader who can peel it. Dryden's couplets look fused — satire IS argument — until you learn the key, and then every name lifts clean off its referent. Inseparability might just be unfamiliarity.
