Where do you look for truth? Shelley's speaker asks the question and in the same breath sneers at the obvious answer: "On tombs?" Epitaphs and carved inscriptions are where we expect solemn statements about the dead. The speaker suggests that the only tomb worth consulting is a human heart. The syntax is twisted, but the sense runs roughly: *for you, my heart has been such a tomb*. Inside it lies "thy dead memory", the memory of the person addressed, kept "from childhood" until now. The poem never says who "thee" is. Judging by the words "from childhood", the memory is a very old one, formed early and carried ever since.
The opening "And" drops us into the middle of a thought, and the title tells us we are reading a fragment. Whatever came before, or after, is missing. What survives is a compact idea: faithfulness as burial. Truth here seems to mean constancy, the refusal to let something change. Yet every image attached to that constancy is an image of death. The memory is "dead", which is a strange thing to call a memory, since memories are supposed to be alive. The heart that guards it "preserves" and "buries" it, and the two verbs pull in different directions. To preserve is to protect, as one might embalm a body or keep fruit through winter. To bury is to hide and cover over. The speaker does both at once, and the poem leaves open whether this is devotion or a kind of morbid hoarding.
The form supports this uneasy balance. The four lines are two rhymed couplets in iambic pentameter, the steady ten-syllable line that feels orderly and closed, like a sealed vault. The first rhyme, "thee" and "memory," is slightly unusual because the second word ends on an unstressed syllable. The line has to lean on that last "-ry" to make the rhyme land, so the word that names the buried thing ends the line in a faint, dying fall. The second couplet, "year" and "there," rhymes fully, and the poem's final word is "there," a fixed spot, like a name on a gravestone.
The rhythm of the sentences matters too. The first line is chopped up by two quick questions, "And where is truth? On tombs?", so it stumbles and sounds almost impatient. Then the rest of the poem runs as one long sentence over three lines, with no full stop until the end. That unbroken stretch mimics the long years it describes, the slow passing of time with nothing interrupting it.
The best word choices all concern time. "Changeful" describes the years: they are full of events and alterations. The last line then opens with "Unchangingly," a long, four-syllable adverb that takes up space and sits heavily in the line. It also has "changing" buried inside it, so the very word for stillness contains the thing it denies. The years move and the heart does not, and the contrast is stated in the poem's own vocabulary. "Has lain" adds to the effect, because lying is what a body does in a grave, and the memory is given the posture of a corpse. The intimate "thee" and "thy" keep the tone personal. Even this grim image is addressed to someone, as if it were a confession or a reproach.
The fragment is worth reading because it turns the heart into a place, a chamber with something laid in it, and then makes us question whether we admire that place. Keeping faith with the past can look like the highest loyalty, but the poem's own language suggests it may also mean refusing to let anything live. It does not choose between those readings. It also ends before it can explain itself, and that unfinished quality suits a poem about something held and never released. In four lines it leaves the reader with a question: is a memory kept unchanged still true, or only still?
