About this artwork

Over engages with ideas about perception, and how we look at and experience art and phenomenon found in the world around us. Its repeated motif of black and white curvilinear lines produces complex optical sensations. Writing about the work in 1979, the artist commented that, ‘The theme of the painting Over is a certain sensation of change: moving from one state to another, a transition enacted through the progression of the elements employed.  Something crosses “over”, turns “over”.  This is a persistent principle of my work which appears almost involuntarily in different guises at different times.’

Bridget Riley

Bridget Riley

Riley was born in London. In the early 1960s she became interested in colour theory. When tiny spots of pure colour are placed close together they will blend on the retina of the eye. Riley began experimenting with optical movement in painting, using squares, lines, circles and spirals. She used black and white at first but moved on to introduce colour in the mid-1960s. Her paintings produce feelings of movement and dislocation in the viewer, and even illusions of colour in her black and white works. Her work has been widely imitated, and she is known as one of the founders of 'Op Art'.
