Swan song

The swan song (ancient Greek: κύκνειον ᾆσμα; Latin: carmen cygni) is a metaphorical phrase for a final gesture, effort, or performance given just before death or retirement. The phrase refers to an ancient belief that swans (Cygnus spp.) sing a beautiful song in the moment just before death, having been silent (or alternatively, not so musical) during most of their lifetime. This belief, whose basis in actuality is long-debated, had become proverbial in ancient Greece by the 3rd century BC, and was reiterated many times in later Western poetry and art.

In Greek mythology, the swan was a bird consecrated to Apollo, and it was therefore considered a symbol of harmony and beauty and its limited capabilities as a singer were sublimated to those of songbirds.

Aesop's fable of "The Swan and the Goose" incorporates the swan song legend as saving its life when it was caught by mistake instead of the goose but was recognized by its song. There is a subsequent reference in Aeschylus' Agamemnon (verses 1444–5) from 458 BC. In that play, Clytemnestra compares the dead Cassandra to a swan who has "sung her last final lament". Plato's Phaedo (84d) records Socrates saying that, although swans sing in early life, they do not do so as beautifully as before they die. Furthermore, Aristotle noted in his History of Animals (615b) that swans "are musical, and sing chiefly at the approach of death". By the third century BC the belief had become a proverb.

Ovid mentions it in "The Story of Picus and Canens" (Metamorphoses, book XIV:320–396): "There, she poured out her words of grief, tearfully, in faint tones, in harmony with sadness, just as the swan sings once, in dying, its own funeral song." The swan was also described as a singer in the works of the poets Virgil and Martial.
