It is a terrible, but also tremendous time. Personally I find it moreover so important for my art to live now.. .These times force you to think over … - Jacoba van Heemskerck

(original version, written by Jacoba in German:) So geht es, wissen Sie, ich bin immer unzufrieden und will immer weiter gehen.

On the whole [the alignment of a series of stained glass windows with the interior of a villa in The Hague] I have thought about all the time.. .I want to focus more on the architecture of the interior in general and that should we do together [with architect Buys].. .Now I was already thinking, the enormous color effect that the window will generate - and that will certainly become powerful - must be accompanied with strong colors - the hall -, otherwise the window itself will be too much isolated. For instance the staircase, could it be painted in strong colors and not [in] oak.. ..deep ultramarine blue or green, with a beautiful colorful carpet.. ..I feel I must make designs for carpets, to create in that way a beautiful unity with the stained glass as a whole. (translation from Dutch, Fons Heijnsbroek, 2018)

This evening the Anthroposophical Society invited me to give a lecture about modern art, on 13 March. They start to wake up here [in the Netherlands].. .Please, tell me something, what I should emphasize, what you find most important. I shall also read something from 'The Spiritual in Art' by [[w:Kandinsky.. .But we still have other views on the whole, isn't it. I don't always agree with Kandinsky, and often more with your views. So please write a little much.. .You know, for me it is always easier to paint my principles. (translation from German, Fons Heijnsbroek, 2018)
