You know the tender side of my work. That side was always dominating me. I feel the joy of that tenderness most strongly when I think of a finch-nest… - Jan Mankes

(original Dutch: citaat van Jan Mankes, in het Nederlands:) ..voerlui, sjouwerslui en schippers.. ..aan het kanaal wordt permanent turf geladen en elk paard staat een half uur stil [tijd voor schetsen].

..Painting never means just never picturing the material things, but it is a psychological function, an expression of how his mind [of the artist] responds to things. So that is quite a difference with: painting is showing the beauty of things. (translation from original Dutch: Fons Heijnsbroek)

It [an owl] is like coming from a fairy-tale, something royal fragile, something that you would never want to touch, Yes to me it has become fully absolute because of that silver breast. (translation from original Dutch: Fons Heijnsbroek)
