Did you know that in 1900 I had the bold idea of renewing German art?.. .First of all I needed to invent a technique of grasping everything while it was in motion, and it was Rembrandts drawings in the Kupferstichkabinett in Munich that showed me how. I practiced seizing things quickly in bold strokes, wherever I was, walking and standing still.. ..and in this way I learned how to depict movement itself, and I found new forms in the ecstasy and haste of this work.. ..and to these forms was added pure colour, as pure as the sun generates it.. ..in line with Goethe's theory [of colours]. It makes pictures much more colorful. Making wood-cuts, which I'd learnt as a fifteen-year-old from my father, helped me to stabler and simpler forms. And armed in this way I returned to Dresden.
