Shelley opens with a promise of enchantment and closes with a sentence of despair. The poem speaks to an unnamed "thou," and the dash in the title keeps that person anonymous. We learn about this figure only through failure. First came a search for companionship among nature's spirits, then a search for love in human eyes. Both left the person lonelier than before. By the end, the only thing left is the sufferer's own soul, "changed to a foul fiend through misery," and the speaker's advice is bleak: do not fight it. "Be as thou art." The Greek epigraph, printed here in Roman letters, appears to pair "tears" with "fate" (*dakrusi*, *potmon*), so the mood is announced before the first line.
The form is tidy, and that tidiness presses on the content. Each of the six stanzas has six lines rhymed *ababcc*, mostly in iambic tetrameter. In every stanza the last line stretches to a longer, ten-syllable line, and that stretch lands like a verdict: "Oft hast thou turned from men thy lonely feet." The rhyme can be cruel in its neatness. In the second stanza "but they" spills over the line break to rhyme with "away," so the rejection arrives in the rhyme itself, as the spirits "Cast, like a worthless boon, thy love away." The final couplet clicks shut with "fate" and "aggravate," and the sense of a closed door is hard to miss.
The imagery works in a deliberate arc. The opening stanza is all softness and half-light: "spirits of the air," "genii of the evening breeze," ghosts whose eyes are "as fair / As star-beams among twilight trees." Nothing here is solid, which is part of the lure and part of the danger. In the third stanza the stars come down to earth as "starry eyes," and now the glow belongs to someone else: "Beams that were never meant for thine, / Another's wealth." The language of money, with "wealth" and "sacrifice," makes the unreturned love sound like a bad investment. The question "still dost thou pine?" is hard to read as sympathy. It sounds as though the speaker is tired of watching the same hope fail.
The fourth stanza turns the poem into a reproach. "Ah! wherefore didst thou build thine hope / On the false earth's inconstancy?" The speaker suggests the mind should have been enough, and that "natural scenes or human smiles" should never have had the power to "steal" and "wind thee in their wiles." Those verbs make landscape and lovers sound like thieves and tricksters. Then the fifth stanza clears the stage. The smiles are "fled," "The glory of the moon is dead," and "Night's ghosts and dreams have now departed." The gentle ghosts of the first stanza have gone, and something worse has taken their place.
That something is the poem's sharpest idea: "Thine own soul still is true to thee, / But changed to a foul fiend." Loyalty has become a torment, because the one thing that has not abandoned this person is the misery itself. The fiend "hangs / Beside thee like thy shadow," a simile that makes escape impossible, since a shadow can only be outrun by leaving the light. The words "scourge" and "severer pangs" add physical cruelty to the picture, and the speaker's advice not to "chase" the fiend sounds more like resignation than comfort. A reader might ask whether this "thou" is really another person at all. The poem never says, but the way it addresses a suffering figure from outside, almost clinically, could be read as a mind talking to itself. That is an inference from the tone, not something the text states.
The poem is worth reading because it takes a favourite Romantic hope, that nature and feeling can answer the lonely heart, and watches it fail. It offers no rescue and no consoling turn in the last stanza. What stays with a reader is the final claim that change itself would "aggravate" the pain, which leaves a gentler beginning ending in a very bleak place.
