Sleep by Henry Wadsworth Longfellow

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.

Argus Panoptes is a giant in Greek mythology known for having a hundred eyes, allowing him to observe everything around him at once without ever truly sleeping. The god Hermes was tasked with killing him, which he accomplished by playing his lyre so beautifully that all of Argus's eyes closed. Longfellow uses Argus as a metaphor for his restless mind, filled with "wakeful eyes" (thoughts) that won't quiet down, and he pleads with Sleep to perform the same feat as Hermes.

An Aeolian harp is a stringed instrument meant to be set in a window or outside, allowing the wind to play it on its own, without any musician. The sound it produces is soft, shifting, and dreamlike. Longfellow uses it to capture the sound of the wind, creating a feeling that's already between waking and sleeping — a perfect invitation to unwind.

It's a metaphor for suffering. A crown typically symbolizes reward or honor, but Longfellow turns his crown into iron — heavy, cold, and unavoidable — labeling it as anguish instead of glory. This image illustrates how pain can feel like a burden imposed on you, something you bear regardless of your desires.

These phrases refer to the Eleusinian Mysteries, the ancient Greek religious rites conducted at Eleusis that explored the cycle of life, death, and rebirth. In this tradition, sleep was known as the lesser mystery since it resembles death — you lose consciousness and give up control — but you eventually wake up. Death is seen as the greater mystery because it represents the ultimate, irreversible form of that same surrender. Longfellow concludes the poem by suggesting that every time we sleep, we are rehearsing for death.

We can't tie the poem to a specific moment in Longfellow's life, but he certainly faced profound grief and fatigue. His second wife tragically died in a fire in 1861, and he struggled with deep depression for years afterward. Alongside this personal tragedy, he had significant professional and social responsibilities. The emotion in the poem — a sincere, deep-seated weariness — feels like a reflection of his lived experience rather than just a literary exercise, even if we don't know the exact circumstances.

The connection weaves throughout the entire poem but is made clear at the end. In Greek mythology, Sleep (Hypnos) and Death (Thanatos) were twin brothers — two aspects of the same reality. Every image in the poem that depicts sleep — closed eyes, eased pain, relinquished breath — equally conveys the essence of dying. Longfellow doesn’t present this as something to fear; instead, he views it as a profound understanding that the ancient Greeks embraced, something we've largely overlooked.

The octave feels urgent and heavy; the speaker is overwhelmed, exhausted, and nearly desperate for relief. The sestet transforms that urgency into something gentler, and by the final lines, it takes on a philosophical tone. This shift is characteristic of the Petrarchan sonnet form, where the sestet "responds" or reframes the issue presented in the octave. In this case, the response isn't a fix for the exhaustion but a deeper insight into the nature of sleep itself.
