Extended Metaphor: Definition, Examples, and How to Write One

John Donne — "A Valediction: Forbidding Mourning" (1633)

Metaphor: Two lovers as the legs of a compass

Donne establishes the comparison and then methodically develops every implication: one leg stays fixed while the other travels; the fixed leg leans toward the moving one; when the roaming leg returns, the fixed leg stands straight again. Each property of the compass is mapped onto the lovers' relationship. The conceit is intellectually demanding and emotionally precise — the rigidity of the compass enacts the faithfulness of love.

William Shakespeare — Sonnet 18 (1609)

Metaphor: The beloved as a summer's day

Shakespeare starts by asking "Shall I compare thee to a summer's day?" — and then spends the sonnet working out why the comparison is imperfect. Summer is too hot, too short, too subject to change. The extended comparison runs through every quality of summer to argue that the beloved exceeds them all. The metaphor's extension is the argument.

Emily Dickinson — "Hope is the thing with feathers" (1891)

Metaphor: Hope as a bird

The bird metaphor extends across the entire poem: hope perches in the soul, sings without words, weathers storms without pausing, is found even in the coldest places. Dickinson maps every property of a bird onto the experience of hope — its lightness, its persistence, its presence in the harshest conditions. The poem's argument is entirely carried by the sustained comparison.

Robert Frost — "The Road Not Taken" (1916)

Metaphor: Life choices as paths in a wood

Frost spends three stanzas attending to the physical properties of the road — how similar the two paths are, how one bends out of sight, how both are covered with leaves. Each observation maps onto the experience of choosing: choices seem more different than they are; you can't see where either leads; both paths are roughly untrodden. The poem's subject is never stated directly — it's entirely enacted through the extended metaphor.

George Orwell — Animal Farm (1945)

Metaphor: Stalinist Soviet Russia as a farm uprising

Every element of the Soviet political system has a corresponding element in the farm: Napoleon is Stalin, Snowball is Trotsky, the pigs are the party elite, the working animals are the proletariat, the farmer is the Tsar. Orwell develops every correspondence with scrupulous consistency across the entire novel. The extended metaphor is so complete that the book functions simultaneously as a children's fable and a precise political critique.

William Shakespeare — "All the world's a stage" (As You Like It, 1599)

Metaphor: Human life as theatrical performance

The world is a stage; all men and women are players; they have their entrances and exits. Jaques extends the metaphor through all seven ages of man, assigning each a theatrical role and costume: the infant, the schoolboy, the lover, the soldier, the justice, the old man, the final dotage. The theatrical metaphor becomes an entire taxonomy of human life. The form — structured enumeration — is inseparable from the content.

John Keats — "Ode to a Nightingale" (1819)

Metaphor: The nightingale's song as immortal art vs mortal human experience

Keats extends the comparison across eight stanzas, developing the contrast between the bird's timeless song and the speaker's mortal suffering. The bird has not been born for death; it was heard by emperors and clowns and Ruth; it offers an escape the speaker ultimately cannot take. The extended metaphor organizes the poem's philosophical argument about art, mortality, and the limits of beauty as consolation.

T.S. Eliot — "The Love Song of J. Alfred Prufrock" (1915)

Metaphor: The evening as a patient etherized on a table

The opening image — "When the evening is spread out against the sky / Like a patient etherized upon a table" — establishes the poem's governing comparison: modern experience as medical numbness. The metaphor extends through Prufrock's paralysis, his inability to act, his observation of life as though through glass. The etherized state recurs in the "restless nights in one-night cheap hotels" and the mermaids who "will not sing to me."

Sylvia Plath — "Lady Lazarus" (1965)

Metaphor: Personal resurrection as circus performance

Plath opens with the resurrection metaphor and extends it relentlessly: she is a "sort of walking miracle," her skin is "bright as a Nazi lampshade," she is unwrapped like a museum exhibit, she charges admission to her dying and rising. The circus / spectacle extended metaphor frames her survival as grotesque entertainment — watched, commodified, cheapened by the audience's fascination. The extension of the metaphor is the argument about spectacle and suffering.

Mark Twain — Adventures of Huckleberry Finn (1884)

Metaphor: The Mississippi River as freedom vs civilization

The river runs through the entire novel as a sustained metaphor for the territory outside social constraint. On the raft, Huck and Jim are free; on the shore, civilization imposes its hypocrisies and violences. Every return to shore is a return to trouble; every push back onto the river is relief. Twain develops the opposition systematically — the river's properties (movement, aimlessness, indifference) all map onto Huck's moral experience.
