A millstone and the human heart are driven ever round;
Editor's note
Longfellow begins by juxtaposing two elements: a millstone, the heavy, circular stone used in flour mills, and the human heart. He suggests that both are *driven ever round* — they never stop, they can't stop. The millstone turns thanks to water or wind, while the heart turns due to desire, worry, longing, and restlessness. This comparison establishes a kind of mechanical logic: both exist to work, and they will keep working regardless of circumstances.

Symbols & metaphors
- The millstone
- The millstone serves as a powerful symbol for the human heart. It's heavy, relentless, and built for a single purpose: to grind. By connecting it to the heart, Longfellow implies that human emotions and desires function like mechanical forces — strong, impersonal, and not something we can easily turn off.
- Grinding
- Grinding is a symbol of both productive work and self-destruction. When the millstone has grain to process, grinding serves a purpose. But when there’s nothing to work on, the two stone surfaces just wear each other out. For the heart, this reflects the contrast between passionate purpose and anxious, aimless rumination.
- Circular motion ("driven ever round")
- The endless rotation embodies obsession, repetition, and an inability to find rest. The heart doesn’t progress in a straight line — it circles back, revisits, and churns. This circular motion is both a source of strength and a potential danger for the heart.
