Leave it to the Germans to solve a mystery and thereby add to the prose of life. Yeats is better, "He tells of the Perfect Beauty"
O cloud-pale eyelids, dream-dimmed eyes,
The poets labouring all their days
To build a perfect beauty in rhyme
Are overthrown by a woman’s gaze
And by the unlabouring brood of the skies:
And therefore my heart will bow, when dew
Is dropping sleep, until God burn time,
Before the unlabouring stars and you.
