Unlike modern times, Nude models were typically required to be modest and drape their faces with cloth in Victorian times. Manet's paintings broke away from many ideologies of his time.

Modernism continues to change and evolve into new forms of art movements such as: impressionism, post-impressionism, cubism, futurism, expressionism, constructivism, de stijl, abstract expressionism, color field painting, lyrical abstraction, geometric abstraction, minimalism, abstract illusionism, process art, pop art, and post-minimalism.
