Bridget Riley

Optical Cut

"The basis of the Op Art movement was a form of geometric abstraction, which was in a way impersonal and not obviously related to the real world. "I couldn’t get near what I wanted through seeing, recognizing and recreating, so I stood the problem on its head. I started studying squares, rectangles, triangles and the sensations they give rise to... It is untrue that my work depends on any literary impulse or has any illustrative intention. The marks on the canvas are sole and essential agents in a series of relationships which form the structure of the painting." (Bridget Riley)"
