John Clare's sonnet to Napoleon contains no battles, no marching armies and no named victories. It praises its subject almost entirely by making everything else smaller. Rival heroes become "puny, vague, and nothingness". An island becomes "a dust-spot in a lake". The whole world shrinks to "a comma" on the page of his victories. The central idea is that Napoleon's ambition was so vast that comparison with anyone else stops making sense: "Fame could find / No parallel."
The poem builds this case through scale. In the second line the grammar itself shrinks the heroes. Two adjectives, "puny, vague", are followed by an abstract noun, "nothingness", so the rivals are first described and then erased. The water imagery is more ingenious. The "little island, on the Atlantic sea" is probably St Helena, though the poem never names it. It is first a speck, then the sea around it is cut down to a "lake", because Napoleon's mind "Swept space as shoreless as eternity." The only real ocean in the poem is his mind, and the physical ocean becomes a pond beside it. The word "shoreless" suggests a mind that nothing could contain, so a small island could hardly be a prison for it.
Clare also takes aim at the present. He calls his own time a "gaudy age / Of heroes", and "gaudy" is a cutting word, suggesting cheap glitter next to real brilliance. Then comes the sun simile: gazing at Napoleon's greatness "made men blind / To merits, that had adoration won / In olden times." This is more double-edged than it first seems. Looking at the sun dazzles you, but it also leaves you unable to see anything else. The compliment carries a hint of cost, since being overwhelmed by one figure means losing your sense of proportion about everyone else. The poem never says whether that is good or bad. It simply dwells on the dazzle, and that silence is worth discussing. Whatever moral questions Napoleon raises, they stay outside the poem.
The most playful image is the last one. The world is "but a comma" on his "page / Of victories". This turns conquest into writing, with Napoleon as author and whole countries as punctuation, a brief pause on the way to the next sentence. The rhymes support the idea. "Age" in line 8, "page" in line 12 and "presage" in line 14 echo each other, so the era, the written record and the failure of prophecy all end up in the same sound. Even the foretelling of his greatness, the poem says, could not have matched it.
The form is another way of showing that he could not be contained. It has the fourteen lines of a sonnet, but the rhymes do not settle into tidy quatrains or a closing couplet. "Mind" in line 6 is answered by "blind" in line 10 and "find" in line 13, and the final two lines rhyme with earlier ones, not with each other. The poem ends without the neat click a sonnet usually promises. The lines are mostly steady ten-syllable iambic beats, which gives the praise a formal, almost monumental tread, but the sentences keep running over line endings ("thy mind / Swept space", "this gaudy age / Of heroes"). The syntax sometimes strains as well. "Thou didst a span grasp mighty to the last" is compressed and slightly twisted, as if the language is working hard to keep up with its subject. The phrase "when thy die was cast" adds a gambler's note to the glory, and "strain" suggests effort at the very edge of what is possible.
Clare is remembered chiefly for poems about the English countryside, so a sonnet that takes the whole world as its stage is striking in itself. It is also useful to read because it shows how much a poem can do with proportion alone. By the end, the reader has seen almost nothing of what Napoleon actually did, only everything else pushed to the margins. The poem is a study of hero-worship as much as a portrait of a hero, and it leaves you wondering whether being dazzled is the same as understanding.
