For – to say a few words on technique – whereas the curved line was used predominantly for reasons of beauty, (Phidias, Michelangelo, Raphael, Rubens) it has been used more and more economically for reasons of truth (Millet, Claude Monet, Paul Cézanne) until it will end as the straight line for reasons of Love.

Such is the future.
