Shelley's lines open with a prayer and close with a rebuke, and the poem's drama lies in the stretch between them. The speaker first asks Arethusa, the spring-nymph tied to Sicilian pastoral song, to "shed" the spirit of her stream over the verse. The wish is oddly specific: may her waters flow "Unmingled with the bitter Doric dew." Set against a fresh stream, "bitter" seems to point to salt water, so the poet is asking for song that stays pure and sweet. The rest of the poem then tests that wish against a sour subject, a man ruined by love. Gallus, a Roman poet and friend of Virgil, suffers an "unworthy love," and the speaker promises to follow his "melancholy loves" while the goats go on browsing "the soft leaves." The calm animals make the grief feel larger.
The most striking move is a quiet reversal. "We sing not to the dead," the speaker says, as if to head off the assumption that this is an elegy. Yet the poem soon behaves like one. The "wild woods" know Gallus's sufferings, and their "echoes" are left hanging in a broken line, which mimics the thing it names. The text as we have it is full of such gaps. The header marks it as only the first twenty-six verses of Virgil's eclogue, and whether through loss or an unfinished draft, the dots leave the reader hearing echoes rather than full statements.
Next the speaker questions the Naiads, the water-nymphs: where were you when love "possessed / Your Gallus?" The answer comes only as a list of places they were *not*. "Not where Pindus is up-piled, / Nor where Parnassus' sacred mount, nor where / Aonian Aganippe expands." Piling up "nor where" clauses suits the "up-piled" mountains, and the effect is oddly cruel. These are the famous haunts of poetic inspiration, and naming them only measures how absent the protectors were. Gallus is a poet, yet the sources of poetry could not save him.
Nature then makes up for the nymphs' absence by grieving with him. The laurels and "myrtle-copses dim" darken, and Maenalus and "the cold crags of Lycaeus" weep. Rock is the least feeling material imaginable, so cold crags weeping signals a total, almost excessive sympathy. Then Sylvan arrives "shaking in his speed" a bundle of "budding wands / And heavy lilies." The spring-like "budding" sits beside the weighted "heavy," and the god's hurry reads like a mourner bringing flowers too late. The speaker's "we knew / Pan the Arcadian" adds a shepherd's eyewitness tone, as if the singer had seen the procession himself.
In form, Shelley writes in English iambic pentameter, flexible enough to take an abrupt, almost spoken "List!" mid-line. His rhymes arrive at a distance, often a line or two later: "stream" and "gleam," then "dew," "pursue," and "knew." The pattern interlocks like terza rima without ever settling into it. This is Shelley's own choice, since Virgil's Latin hexameters did not rhyme. The rhymes keep the lament flowing, much like the stream the poem begins with, and they give the English a song-like lift.
The closing couplet changes the voice completely: "'What madness is this, Gallus? Thy heart's care / With willing steps pursues another there.'" After lines of ornate lament, the plain question lands hard. In Virgil's eclogue the god Apollo speaks here, and the "heart's care" is Gallus's beloved. The couplet's snapping rhyme on "care" and "there" is the poem's most direct statement. Love is called madness, and the sharpest pain is in "willing steps": the beloved has chosen to go.
What makes the fragment worth reading is how it shows a landscape taking on human feeling, a pastoral habit that Shelley's English handles with real grace. The mountains, woods and gods all bend toward one man's heartbreak, and the last lines suggest that all this sympathy cannot change the simple fact of another person's choice.
