Cubism
The most well known cubist artists are Braque and Picasso of course. I
personally prefer Juan Gris' paintings.
Still life before an Open Window: Place Ravignan 1915.
"Only the [painters mathematics] are capable of establishing the composition
of the picture. It is only the architecture, which can give birth to the
subject, that is to say, an arrangement of certain elements of reality called
forth by the composition.", Juan Gris.
