A postcubist movement in painting proposed by Amedée Ozenfant and Charles-Eduoard Jeanneret (aka.
Le Corbusier) in their 1918 manifesto
Après le Cubisme.
Purism was characterized by the application of
pseudoscientific ideas to the visual arts, and the use of geometric clarity and flat
isometric projection.
The movement was not adopted by other painters.
The subject matter of the Purist canvas was limited to 'objet-types', i.e., mass-produced objects of use, such as bottles, pipes, glasses, bentwood chairs, etc
Mass-produced objects were allowed because they were seen to have stood the test of 'mechanical selection', an analogue to Darwin's natural selection.
