Untitled (Fragment 1) 1965

Bridget Riley’s *Untitled (Fragment 1)* is a prime example of Op Art, a movement that emerged in the 1960s. Riley utilizes black and white stripes to create the illusion of movement and depth, playing with the viewer’s perception of space and form. This piece, created in 1965, reflects the artist’s fascination with geometric patterns and their ability to evoke optical sensations. The precise, bold lines and stark contrasts characteristic of Op Art are present in this work, captivating the viewer with its optical illusions and dynamic energy.
