• And if joy were not on the earth, There were an end of change and birth, And Earth and Heaven and Hell would die, And in some gloomy barrow lie Folded like a frozen fly.

    William Butler Yeats: And if joy were not on the earth,
There were an end of change and birth,
And Earth and Heaven and Hell would die,
And in some gloomy barrow lie
Folded like a frozen fly.
