“To keep it short and simple.... you take the subject, that is for example the wood, and the colour, the paint. You compose the subject, the realistic subject, you make a fantastic shape.

(original Dutch, citaat van Schelfhout, uit zijn brief:) Hierbij 3 teekeningen die ik voor UE. Vervaardigd hebt, het zal mij genoegelijk zijn, indien dezelve aan uwe verwachting en aan het [doel], waar voor zie dienen moeten [voor het maken van een schilderij], zullen beantwoorden. De 2 landschapjes zijn gedachten, maar het gene dat het maanlicht voorsteld, is het kasteel te Doorenwaart in Gelderland. Ik heb ook van dat zelve onderwerp een schilderij geschilderd waar van ik veel genoege gehad heb te Amsterdam [aangekocht door A. B. Roothaan aldaar]
