Bob and Wheel
Quick answer: Bob and wheel is a medieval stanza device: a very short bob line followed by a rhyming wheel of short lines. Learn how it works in Sir Gawain and beyond.
The bob and wheel is a stanza-ending device from medieval English poetry: after a run of long unrhymed alliterative lines, the poet drops in a very short line of one or two stresses, the bob, followed by four short rhyming lines, the wheel. Together the five lines usually rhyme ababa, with the bob supplying the first a-rhyme. The effect is a sudden gear change, from the long rolling stride of alliterative verse to a quick, chiming little stanza tail.
Poets and scholars meet the device chiefly in Sir Gawain and the Green Knight, the late fourteenth-century masterpiece where every stanza ends with a bob and wheel. It matters to modern writers because it demonstrates something timeless: a sharp change of line length and sound can summarise, undercut or ironise everything that came before it. The medieval poet invented, in effect, a built-in punchline mechanism.
How It Works
The bob is tiny, often just two or three words, and it pivots the stanza. The wheel then spins out four compact lines, typically of three stresses each, rhyming with alternating pattern back to the bob. Here is an original modern illustration of the shape: after several long descriptive lines about a storm, a poet might close: 'and still / the house held on through spite, / the windows white with hail, / the night a slammed-shut gate, / the morning strangely pale.' The two-word bob 'and still' turns the description toward endurance, and the wheel condenses the storm into four rhymed strokes.
The rhythm change is the real trick. Long alliterative lines have no rhyme, so when the wheel starts chiming, the reader's ear registers a formal event: the stanza is closing, a summary or twist is coming.
Where You Will See It
Sir Gawain and the Green Knight is the showpiece: 101 stanzas, each rounded off with a bob and wheel that often delivers a sly comment, a plot turn or a flash of foreboding, such as the moment the Green Knight's severed head speaks. The device appears elsewhere in the alliterative revival of the fourteenth century and in some medieval lyrics and romances, but nowhere with Gawain's consistency. Later poets borrowed the spirit rather than the letter: any short rhymed coda after long free lines, a move you will spot in some contemporary stanzas, is the bob and wheel's descendant.
How to Use It in Your Own Poems
You do not need to write Middle English alliterative verse to profit from the pattern. Draft a stanza of long, loose, unrhymed lines, then close it with one stub line and a small rhymed quatrain. Give the wheel a distinct job: summarise the stanza, contradict it, or zoom in on one detail.
The danger is cuteness. Because the wheel rhymes and the rest does not, it can sound like a jingle stapled to a serious poem. Keep the diction of the wheel continuous with the body of the stanza, and let the rhymes be quiet, even slant, if the material is grave. Judges who score language and structure together tend to reward exactly this kind of controlled contrast.
What poets can take from this
- Keep the bob to one or two stresses; its abruptness is the whole point.
- Give the wheel a clear function, such as summary, irony or foreshadowing, rather than mere decoration.
- Use slant rhyme in the wheel if full rhyme sounds too jaunty for your subject.
- Let the long lines before the bob run genuinely long, so the contrast in line length registers.
- Study a few stanzas of Sir Gawain in translation to hear how the wheel changes the stanza's temperature.
Try it yourself
Write a poem describing a physical task, such as chopping wood or kneading dough, in six to eight long unrhymed lines, then finish with a bob and wheel in which the short lines reveal what the speaker was really thinking about the whole time.
Questions
Which poem is famous for the bob and wheel?
Sir Gawain and the Green Knight, written in the late fourteenth century by an anonymous poet known as the Gawain poet or Pearl poet. Every one of its stanzas ends with a bob and wheel.
What is the rhyme scheme of a bob and wheel?
Usually ababa across the five short lines, with the bob providing the first a-rhyme and the four wheel lines alternating from there. The bob carries one or two stresses and the wheel lines usually three.
Can I use a bob and wheel in modern free verse?
Yes, and it works well: close a stanza of long unrhymed lines with a stub line plus a small rhymed quatrain. The shift in length and sound gives you a built-in place for a twist or summary.
