Somewhere online I saw photos of where The Dutchman lived while creating some of the paintings - dirty, dreary, lifeless, depresssing places. To see that all around and to imagine and create the mini-worlds in those painting - with their vivid, wild use of color and texture - is wondrous and wonderful.
I think he sort of lived in his own world. He was def pretty neurodivergent, in some way.
I [sort of] remember a movie, once, that had a kid basically doing a "Don Quixote" on the world, where his vision of everything was kind of wondrous.
Don't remember it well enough to recall its name, though...
