From the Greek of Plato by Percy Bysshe Shelley

The original Greek epigram is often thought to be directed toward Aster, a student of Plato whose name translates to star in Greek. This connection gives the star imagery a clever twist on his name. In Shelley's translation, the address is more general — using "thou" — allowing it to serve as a tribute to any cherished individual who has passed away.

Hesperus is the ancient Greek name for the evening star — the planet Venus as it shines in the western sky right after sunset. The Greeks also referred to Venus as Phosphorus or Eosphorus when it rose before dawn. The entire idea of the poem hinges on the fact that these names refer to the same celestial body viewed at different times.

The epigram is attributed to Plato in ancient sources, yet scholars have debated for years whether he truly wrote it. It shows up in the Greek Anthology, a collection of classical Greek poems put together long after Plato's death. Regardless of its authorship, it was well-known in antiquity, prompting Shelley to translate it.

Because it translates a Greek epigram—a concise and impactful form often found on tombstones and monuments. The essence of an epigram is to convey something deep in as few words as possible. Shelley's four lines capture the same brevity of the original.

It suggests that death isn't an end but rather a relocation of light. The person was the brightest star among the living; now they shine as the brightest star among the dead. The essence of the soul remains the same — only the sky it illuminates changes. This perspective offers a comforting, almost philosophical take on mortality.

Shelley is writing in the early 19th century, and thou/thy were already fading from common use. Poets employed them to convey elevated, formal, or intimate address — the type of language you'd reserve for prayer or for someone you hold dear. It also complements the classical, monumental tone of the epigram.

The poem shifts between longer and shorter lines, generally sticking to iambic pentameter for the longer ones and iambic dimeter for the shorter. This gives it a soothing rise-and-fall rhythm, reminiscent of a slow, dignified breath — quite appropriate for a poem that explores death and transformation.
