But my knowledge of Marxism was limited to knowing that Marx was a Jew, and that he had a long white beard. I said to Lunatcharsky [the political communist commissar for Education]: 'Whatever you do, don't ask me why I painted in blue or green, and why you can see a calf inside the cow's belly, etc. On the other hand you're welcome: if Marx is so wise, let him come back to life and explain it himself'. I showed him my canvases.
