To be honest, I don’t know much about the names dropped below, but the book about Caspar David Friedrich linked above is worth checking out or even buying.

[Caspar David] Friedrich’s own destiny is part of the psychological landscape of his age. In almost every one of the poems by Wihelm Müller that Schubert set in his Winterreise, there are lines that seem to mirror the painter’s distraction and dread of human contact:

Durch des Bergstroms trock’ne Rinnen
Wind’ ich ruhig mich hinab–
Jeder Strom wird’s Meer gewinnen
Jedes Leiden auch sein Grab. (Irrlicht)

(Down the mountain stream’s dry gullies
I calmly pick my way
Every stream will reach the sea,
Every sorrow finds its grave.)
