In perspective drawing, the viewer's eye-level is the horizon.
Piet Mondrian, p. 226
Mathematicaly speaking, this is a bias picture. Does art even at a time have any laws, when the era of one recipe for all is finished? It is perhaps not so surprising that facts, logic, and knowledge can be bent to accord with a person’s subjective worldview.
“In science, new knowledge builds on and refines the old. In art, according to common caricature, the new eclipses the old and rewrites all the rules”
It was cart-before-the-horse time in bending the rules.
Interpretation of art guidelines is subjective, once in a while we could bend the rules. Buttonholing humor is a beautiful theoretical answer, because our world is marked by great differences in pictures ability to crystallize imagination.
Never, even as a child, would I bend to a rule.
Claude Monet, According to Cocker
Drawing taught me how to survive.
