“I worked for months on this painting [title 'The Stone-wheelbarrow of C. Adema', 1977], for instance that well-bucket on the wheelbarrow I painted a twenty times or more, and it is constructed exactly as nature has shaped it. I want to make it harder and harder for myself. 'That's how it is' doesn’t exist for me. Deepening, that's what it is all about. My wish is to make in due time a small painting in which I can hardly discover any longer that it is painted, that it is just there, like that. Just something very simple. (translation, Fons Heijnsbroek, 2018)”
