Art is not only the product of artistic inspiration, it is also determined by the social context of an artist. The avant-garde was ideologically determined by Western Esotericism, especially spiritualism, modern theosophy and anthroposophy. Genealogical methods uncover networks of artists, which not only run ‘vertically’ in generations, but also in ‘horizontal’ lines between families.

This essay mainly describes the family ties between the families Van Stolk, Favauge, Kalff, Van Gogh, Du Quesne (van Bruchem), Bourbon and Muijsken.
