Since I am quoting Dunsany, though, it is worth remembering that he was an ally of the ancient things. The ancient things renew.
THE RETURN OF SONG
"The swans are singing again," said to one another the gods. And
looking downwards, for my dreams had taken me to some fair and
far Valhalla, I saw below me an iridescent bubble not greatly larger
than a star shine beautifully but faintly, and up and up from it looking
larger and larger came a flock of white, innumerable swans, singing
and singing and singing, till it seemed as though even the gods were
wild ships swimming in music.
"What is it?" I said to one that was humble among the gods.
"Only a world has ended," he said to me, "and the swans are coming
back to the gods returning the gift of song."
"A whole world dead!" I said.
"Dead," said he that was humble among the gods. "The worlds are
not for ever; only song is immortal."
"Look! Look!" he said. "There will be a new one soon."
And I looked and saw the larks, going down from the gods.
