SLEEP

Henry Wadsworth Longfellow

Lull me to sleep, ye winds, whose fitful sound Seems from some faint Aeolian harp-string caught; Seal up the hundred wakeful eyes of thought As Hermes with his lyre in sleep profound The hundred wakeful eyes of Argus bound; For I am weary, and am overwrought With too much toil, with too much care distraught, And with the iron crown of anguish crowned. Lay thy soft hand upon my brow and cheek, O peaceful Sleep! until from pain released I breathe again uninterrupted breath! Ah, with what subtile meaning did the Greek Call thee the lesser mystery at the feast Whereof the greater mystery is death!

§01Quick summary

What this poem is about

A weary speaker pleads with Sleep to quiet his racing, fatigued mind, much like Hermes once lulled the hundred-eyed giant Argus into slumber. The poem concludes with a shock: the ancient Greeks referred to sleep as a "lesser mystery," considering death the greater mystery that lies beyond it. It’s a brief, beautiful appeal for rest that subtly reminds us of the thin line between sleep and death.

Stanza by stanza, with notes

  1. Lull me to sleep, ye winds, whose fitful sound / Seems from some faint Aeolian harp-string caught;

    Editor's note

    Longfellow begins with a plea, asking the winds to lull him to sleep. An **Aeolian harp** is a stringed instrument that the wind plays — the winds are already creating music, and he desires that soft, distant sound to help him drift off. The mood is one of tiredness and yearning right from the start.

  2. Seal up the hundred wakeful eyes of thought / As Hermes with his lyre in sleep profound

    Editor's note

    Here, the speaker likens his own restless, overactive mind to **Argus Panoptes**, the hundred-eyed giant from Greek mythology. In the story, the god Hermes played his lyre so soothingly that all of Argus's eyes fell shut in sleep. Longfellow wishes for Sleep to work the same magic on his thoughts — putting each one to rest, one by one.

  3. For I am weary, and am overwrought / With too much toil, with too much care distraught,

    Editor's note

    The speaker sets aside the mythology for a moment and speaks directly: he’s exhausted. The repeated phrase "too much" drives the message home—this isn't just being tired, but a deep, bone-weary fatigue from overwork and stress. "Distraught" and "overwrought" rhyme and amplify each other, making the weariness feel almost tangible.

  4. And with the iron crown of anguish crowned.

    Editor's note

    This closing line of the octave presents the poem's most powerful image. A crown typically represents glory, but this one is **iron** — cold, heavy, and unyielding — symbolizing suffering instead of honor. The word "crowned" at the end resonates with "crown," trapping the speaker in his own pain.

  5. Lay thy soft hand upon my brow and cheek, / O peaceful Sleep! until from pain released

    Editor's note

    The sestet moves from mythology to a direct and tender address. Sleep transforms into a gentle figure with a soft hand, contrasting sharply with the iron crown. The speaker simply desires the pain to cease, even if just for a moment. The mention of "brow and cheek" adds an intimate, human touch to the longing, steering it away from the grand.

  6. Ah, with what subtile meaning did the Greek / Call thee the lesser mystery at the feast

    Editor's note

    The poem takes a sudden turn in its final three lines. Longfellow remembers that the ancient Greeks — especially regarding the Eleusinian Mysteries, which were religious rites focused on life and death — referred to sleep as a "lesser mystery." The term "subtile" (an older spelling of *subtle*) suggests that this ancient concept holds a hidden depth that deserves exploration.

  7. Whereof the greater mystery is death!

    Editor's note

    The final line hits with the weight of a quiet thunderclap. Everything the speaker has been yearning for — rest, release, the closing of eyes — serves as a small rehearsal for death. In Greek mythology, sleep and death were like twin brothers (Hypnos and Thanatos). Longfellow doesn’t mention this to scare us; instead, he shares it with a sense of reverent acceptance, suggesting that the proximity of these two states can actually offer comfort.

§04Tone & mood

How this poem feels

The tone throughout the octave feels both weary and yearning — this is someone who’s genuinely at the end of their rope, not just acting exhausted. When we reach the sestet, the mood shifts to something almost tender as the speaker speaks directly to Sleep. Finally, the last couplet brings a sense of quiet awe: it’s not about dread, but rather a calm, philosophical acknowledgment that sleep and death are close companions. The overall effect is soft and reflective, resembling a prayer whispered in a dark room.

§05Symbols & metaphors

Symbols & metaphors

The Aeolian harp
A harp played by the wind, needing no human touch. It marks the line between waking and sleeping — a sound that's almost nonexistent, half-imagined, the sort of sound that lulls you into a deeper state.
The hundred eyes of Argus / thought
Argus Panoptes, the giant with a hundred eyes, represents the speaker's own restless and ever-alert mind. Each eye symbolizes a thought that keeps observing and racing, never pausing. Only sleep can finally shut them all.
The iron crown of anguish
A crown typically represents victory or nobility, but iron symbolizes hard work and hardship. Longfellow flips this idea: the speaker is "crowned" not with honor but with suffering, and this burden is one he must bear, regardless of his desires.
Sleep's soft hand
Personified Sleep is touched softly and warmly — contrasting with the cold iron crown. The hand resting on the brow resembles a parent's touch or a healer's hand. It conveys comfort, not emptiness.
The lesser mystery / the greater mystery
Drawn from the Greek Eleusinian Mysteries, these phrases suggest that sleep and death are interconnected. Sleep acts as a rehearsal — a daily, reversible experience of the ultimate surrender that death signifies.

§06Historical context

Historical context

Longfellow wrote this Petrarchan sonnet in the mid-1800s, a time when he was among the most popular poets in the English-speaking world. He faced profound personal loss — his first wife passed away in 1835, and his second wife, Fanny, tragically died in a fire in 1861, leaving him heartbroken for years. It's hard to say if this poem was a direct response to a particular loss, but it certainly reflects a man who had experienced deep exhaustion and sorrow. The poem references classical mythology — specifically the tale of Hermes and Argus from Ovid's *Metamorphoses* — along with the Greek religious tradition of the Eleusinian Mysteries, which focused on death and rebirth. As a Harvard professor of modern languages with a strong background in classical literature, Longfellow integrated these references seamlessly, making them feel inherent to the poem rather than merely decorative.

§07FAQ

Questions readers ask

It's a **Petrarchan (Italian) sonnet** — 14 lines split into an octave (8 lines) and a sestet (6 lines). The octave introduces the problem or plea, while the sestet moves toward a resolution or presents a new idea. Longfellow adheres to the traditional ABBAABBA rhyme scheme in the octave and then changes it in the sestet, which is standard for this form.
