What an allusion is, and why poets use it
An allusion is a brief, indirect reference to something the poet expects readers to share: a myth, a Bible story, an earlier poem or play, a historical event or a well-known figure. It may be a name (“Penelope”), a phrase that echoes a famous line, or a situation that recalls a known story. It is not the same as a quotation, which reproduces words and marks them as someone else’s; an allusion refers, often in passing, and may not use the original words at all.
Allusions work because of shared knowledge. When a poet mentions a story the reader knows, the whole story arrives with the mention: its characters, its mood, its moral. The poet does not have to build those associations from scratch. This is why an allusion can create an emotional or intellectual association very economically. A single name can make a modern scene feel ancient, or make an ancient authority feel suspect.
A poem can stand in several relationships to the source it alludes to.
- Honour or extend it. The poem draws on the authority or dignity of the source and may bring it up to date.
- Undercut it. The poem uses the source ironically, so that the reference shows how far reality falls short of the ideal, or how false the ideal was.
- Complicate it. The poem both uses and questions the source, holding two attitudes at once.
Your commentary should say which of these is happening and how you can tell from the words around the allusion.
A method for allusion
- Recognise it. What name, phrase or situation seems to refer to something outside the poem? Notes, titles and the poem’s own context often help.
- State the source in one sentence. Say what the source is and what happens in it, no more than you need.
- Choose the associations. Which of the source’s qualities does the poem use (faithfulness, authority, glory, suffering, antiquity)? Not every association applies.
- Judge the stance. Does the poem honour, undercut or complicate the source? Quote the nearby words that show it.
- Link to the whole. How does the allusion change your understanding of the speaker’s attitude and the poem’s meaning?
If you do not recognise the reference, you can still do steps 3 to 5. Look at the poem’s tone, the words surrounding the reference, and what the speaker does with it. Unseen-poem questions generally supply a note, but the poem’s own context is often enough.
Worked example 1: an allusion turned into an accusation
Wilfred Owen’s “Dulce et Decorum Est” was written in 1917 and published in 1920, after he was killed in 1918. The poem describes soldiers retreating from a gas attack and one man who does not get his helmet on in time. The speaker sees him “guttering, choking, drowning” and says the sight returns “In all my dreams”. The poem ends by addressing a reader:
My friend, you would not tell with such high zest
To children ardent for some desperate glory,
The old Lie: Dulce et decorum est
Pro patria mori.
Recognise. The Latin phrase is a quotation, but its use here is also an allusion to a long tradition. The words come from an ode by the Roman poet Horace and mean “It is sweet and fitting to die for one’s country.” It was a well-known motto in the education of the poet’s generation.
Associations. The phrase carries classical authority, the dignity of schoolroom Latin, and the idea that war is noble and glorious. “Sweet” is a surprising adjective for death, and it is the word the poem is about to contradict.
Stance. The poem undercuts the source. It does not argue against the Latin at the start; it describes what happened to a man in a gas attack (“his hanging face, like a devil’s sick of sin”) and only then names the Latin motto, calling it “The old Lie”. The words around the allusion (“high zest”, “children ardent for some desperate glory”) reveal that the motto has been taught to the young as an inspiration. “Old” tells us the lie has been told for generations.
Link to the whole. Because the allusion arrives last, the whole poem works as a reply to it. The graphic details are evidence; the Latin tag, which sounded noble, now sounds hollow. Owen’s strategy relies on the reader’s recognition of the phrase, so the allusion is both the target and the final blow.
Model commentary: “By ending on Horace’s ‘Dulce et decorum est’ and calling it ‘The old Lie’, Owen turns a classical slogan of honour into an accusation, since the reader has just watched the death that the Latin phrase calls ‘sweet’.”
Worked example 2: an ancient listener on a modern shore
Matthew Arnold’s “Dover Beach” (published 1867) is spoken by a man at a window on the English coast, listening to waves pull pebbles back and forth. He says:
Sophocles long ago
Heard it on the Ægean, and it brought
Into his mind the turbid ebb and flow
Of human misery: we
Find also in the sound a thought,
Hearing it by this distant northern sea.
Recognise. Sophocles was an ancient Greek tragic playwright, and the Aegean is the sea off Greece. The poem imagines that he heard the same sound and thought of “human misery”.
Source and associations. The reference calls up antiquity, tragedy and the idea that human suffering is a permanent condition. A Greek dramatist of the fifth century BC is a figure of cultural authority.
Stance. The poem honours and extends its source. By saying “we / Find also in the sound a thought”, the speaker places himself in a long line of listeners: the sea’s sound has meant sadness for two and a half thousand years. Then it complicates the source: his own thought is specific to his time. In the next stanza he says that “The sea of faith / Was once, too, at the full” and now he hears “Its melancholy, long, withdrawing roar”. The ancient sadness is general; his is the sadness of lost certainty.
Link to the whole. The allusion makes the poem’s mood feel old and universal at first, and then it narrows to a particular modern anxiety. This prepares the poem’s final plea, “Ah, love, let us be true / To one another!”, in a world that “Hath really neither joy, nor love, nor light”. The Greek reference supports the claim that private loyalty is what remains when public meaning has withdrawn.
Model commentary: “The allusion to Sophocles gives the speaker’s sadness an ancient pedigree, yet by adding that ‘we’ find ‘also’ a thought of our own, Arnold sets modern doubt beside classical tragedy, so the poem’s final appeal to love answers a loss that is new as well as old.”
Weak and strong versions side by side
| Weak | Why it falls short | Stronger |
|---|---|---|
| “Owen alludes to Latin.” | Identifies a language, not an allusion or its function. | “Owen alludes to Horace’s motto that dying for one’s country is sweet and fitting, then calls it ‘The old Lie’, turning an inherited slogan into an accusation.” |
| “The reference to Sophocles shows the poet is educated.” | Describes the poet, not the poem. | “The reference to Sophocles gives the speaker’s sadness an ancient pedigree, then the word ‘also’ sets a distinctively modern doubt beside it.” |
| “The allusion adds meaning.” | Could be said of any allusion. | “The allusion brings the associations of glory and authority, which the poem’s graphic details then contradict.” |
| “I do not know what this reference means.” | Gives up. | “Although the reference is unfamiliar, the speaker’s bitter tone and the phrase ‘old Lie’ show that the poem is attacking what the reference stands for.” |
Common misconceptions
- “An allusion is just a quotation.” A quotation reproduces words. An allusion refers, often briefly, to a shared story or figure.
- “I must retell the source.” Say only what bears on this poem, in a sentence or two.
- “An allusion always honours its source.” Poets often use allusions ironically, to contradict what the source stands for.
- “If I do not recognise it, I cannot comment.” You can still describe the associations, tone and stance from context.
- “Showing that I know the source is the answer.” The credit is for explaining what the allusion does in this poem.
- “One allusion is one meaning.” A source has many associations; choose the ones the poem activates and explain why.

Quick questions
What if I do not recognise the allusion?
Describe what the words suggest in context and what the speaker's tone toward them is. Questions on an unseen poem generally supply the notes you need or can be answered from the poem's own context.
Is an allusion the same as a quotation?
No. A quotation reproduces words and marks them as someone else's. An allusion refers indirectly, often in a phrase or name, and may not use the original wording at all.
Should I explain the whole source story?
No. Say only what the allusion contributes to this poem: the one or two associations that bear on your argument.
