Mr. Rennie cites, also: “In his Phaedro, Plato makes Socrates thus express himself: ‘When swans perceive approaching death, they sing more merrily than before because of the joy they have in going to the God they serve; but men, through fear of death, reproach the swans, saying that they lament their death and sing their grief in sorrowful tones.’ After digressing to assert that no bird sings when either hungry or sorrowful, he resumes, ‘Far less do the swans sing out of grief, which, by reason of their belonging to Apollo, are diviners, and sing more joyfully on the day of their death than ever before, as foreseeing the good that awaits them in the other world.’” Charles de Kay wrote: “Not the magnificence merely, but the element of superstitious reverence accounts for the frequency of the swan as a crest and charge of coats of arms,” stating that in heraldry the swan runs back through heraldic devices to totemism, and that among the “oath-birds” which wizards of Lapland called upon in their incantations, the swan often figured. It is also asserted that German local legends retain the idea of the swan as an uncanny bird, prophetic of death or the under world, and that the Klagesee, or Lake of Complaining, near Liban, was so named from the numbers of musical swans that congregated there. Pliny says, “Some affirm that swans sing lamentably a little before death, but untruly, I suppose, for experience of many has shown the contrary.” But Aristotle says, “Swans are wont to sing, particularly when about to die, and mariners in African seas have observed many of them singing with a mournful voice, and expiring with the notes of their dying hymn.” Cicero affirmed that Lucius Crassus spoke with the divine voice of a swan about to die; while Homer makes no allusion to their singing, but mentions their “flying round the springs of Cayster, clanging on sounding pinions.” Oppian asserts, “They sing at dawn before the rising of the day as if to be heard more clearly through the still air. They also sing on the sea-beach, unless prevented by the sounds of storms and boisterous weather, which would not permit them to enjoy the music of their own songs. Even in old age, when about to die, they do not forget their songs, though they are more feeble than in youth, because they cannot so well erect their necks and expand their wings. * * * “They are invited to sing by Favonius, and as their limbs become sluggish and their members deficient in strength when death approaches, they withdraw to some place where no bird can hear them sing, and no other swans, impelled by the same cause, may interrupt their requiem.”
