Plastic geometry has been referenced in relation to Cubism, Vorticism, Situationism \- in particular situography.

## Cubism and Vorticism

[edit | edit source]

"Most of Picasso’s latest work (on canvas as well) is a sort of machinery. Yet these machines neither propel nor make any known thing : they are machines without a purpose. It you conceive them as carried out on a grand scale, as some elaborate work of engineering the paradox becomes more striking, These machines would, in that case, before the perplexed and enraged questions of men, have only one answer and justification, If they could suggest or convince that they were MACHINES OF LIFE, a sort of LIVING plastic geometry, then their existence would be justified.

\- Wyndam Lewis, Blast 1, 2 July 1914

## Situology

[edit | edit source]

"The point of departure of situography, or of plastic geometry, must be Situ analysis developed by Poincaré, and pushed in an egalitarian direction under the name topology. But all talk of equalities is openly excluded, if there aren't at least two elements to equalize. Thus the equivalence teaches us nothing about the unique or the polyvalence of the unique, which is in reality the essential domain of situ analysis, or topology. Our goal is to set a plastic and elementary geometry against egalitarian and Euclidean geometry, and with the help of both to go towards a geometry of variables, playful and differential geometry."

Asger Jorn, Internationale Situationniste #5 (December 1960)
