“We seek to veil ourselves in youth’s desire.
Let the sun shine on, behind me, then!
The waterfall that splits the cliffs’ broad edge,
I gaze at with a growing pleasure, when
A thousand torrents plunge from ledge to ledge,
And still a thousand more pour down that stair,
Spraying the bright foam skywards from their beds.
And in lone splendour, through the tumult there,
The rainbow’s arch of colour, bending brightly,
Is clearly marked, and then dissolved in air,
Around it the cool showers, falling lightly.
There the efforts of mankind they mirror.
Reflect on it, you’ll understand precisely:
We live our life amongst refracted colour.”

Goethe, Faust (translated by A S Kline)
