"Friday 11. I have found there [at the [[w:Mauritshuis|museum 'Mauritshuis'] ]] already refuge - in front of Potter's big Bull. That is I started to copy the sheep with the lamb, which will not be a easy task, notwithstanding its great simplicity. The longer I look at that painting, the more beautiful things become visible to me, and when I wasn't convinced for sure that I was sitting in front of my painting easel in The Hague at the Mauritshuis, I would believe that the animals were alive and were - just as in the meadows in Oosterbeek - staring at me with their stupid faces, and asking: - what are you doing there? (translation from the Dutch original: Fons Heijnsbroek)"
