  • The phrase "Swan song" is a reference to an ancient belief that the Mute Swan (Cygnus olor) is completely mute during its lifetime, except for singing a single, heartbreakingly beautiful song just before it dies.

    It has been known since antiquity that this belief is false. In A.D. 77. Pliny the Elder refuted it in Natural History (book 10, chapter xxxii: olorum morte narratur flebilis cantus, falso, ut arbitror, aliquot experimentis, "observation shows that the story that the dying swan sings is false").

    By extension, swan song has become an idiom referring to a final theatrical or dramatic appearance, or any final work or accomplishment.
