Marcel Duchamp

Since Courbet, it's been believed that painting is addressed to the retina. That was everyone's error. The retinal shudder! Before, painting had other functions: it could be religious, philosophical, moral... our whole century is completely retinal, except for the Surrealists, who tried to go outside it somewhat.

French Artist

The last hundred years have been retinal; even the cubists were. The surrealists tried to free themselves, and earlier so had the dadaists, but unfortunately, these latter were nihilists and didn't produce enough to prove their point, which, by the way, they didn't have to prove - according to their theory.

In French, there is an old expression, la patte, meaning the artist's touch, his personal style, his 'paw'. I wanted to get away from la patte and from all that retinal painting.

The term 'retinal' often appears in discussions about maintaining good eye health and preventing vision problems.

Eye Health

'Retinal' is used in the context of medical imaging techniques specific to eye examinations.

Medical Imaging

When learning about various eye diseases or conditions, 'retinal' is often a descriptor for their location.

Vision Conditions

'Retinal' in biochemistry involves complex processes and is used in advanced discussions about eyesight.

Complex Biology

In biochemistry contexts, it's used with words like 'pigments', 'molecule', indicating substances related to vision.
