O dearest, canst thou tell me why
The rose should be so pale?
And why the azure violet
Should wither in the vale?

And why the lark should in the cloud
So sorrowfully sing?
And why from loveliest balsam-buds
A scent of death should spring?

And why the sun upon the mead
So chillingly should frown?
And why the earth should, like a grave,
Be moldering and brown?

And why it is that I myself
So languishing should be?
And why it is, my heart of hearts,
That thou forsakest me?

Heinrich Heine
