This may be one of those times when the ‘style’ was an incidental side effect of severe and chronic mental illness.
Bosch struggled with what may have been schizophrenia for years. After finishing this piece “Earthly Delights”, his family had him committed to an asylum. Salvador Dali was more a fetishist with OCD tendancies, same as Mozart. Both Dali and Mozart showed strong fascination with coprophilia.
Do you have a reference on Bosch being put away in a mental institution at any point in his life? It’s the first I’ve heard of it.
