I was in Rotterdam, but the exhibition there was horrible. Le Fauconnier has nothing to tell anymore. He has a dirty color now and has become a real … - Jacoba van Heemskerck

For you it must be a great satisfaction that you have done so much for modern art. If Der Sturm had not worked like this for ten years then Germany would not have been at the forefront of the movement. (translation from Dutch, Fons Heijnsbroek, 2018)

version in Dutch / citaat van Jacoba van Heemskerck, in het Nederlands vertaald: ..ik ben zo vaak met mijn werk in Duitsland dat ik helemaal tot de Duitse modernen behoor.. .Ik wil u openlijk bekennen dat ik de nieuwe schilderkunst in mijn vaderland niet erg hoog aansla. Daarom heb ik ook niet erg veel kennissen onder de schilders. Alles is hier zo weinig vooruitstrevend. De mensen herbben het veel te goed. Het is erg moeilijk wakker te blijven aangezien allen hier slapen. In Duitsland voel ik me veel meer thuis.

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.
