Bridget Riley’s Bagatelle 1 (2015) is a striking example of her exploration into optical abstraction, showcasing her mastery in creating visual dynamism through geometric forms. Bagatelle 1 features an arrangement of triangular forms, some with straight edges and others with curved sides, meticulously organized to create a sense of movement and visual tension. The monochromatic palette emphasizes the interplay between shape and space, inviting viewers to engage with the artwork's rhythmic structure. The title "Bagatelle," referencing a French billiards game, alludes to the erratic and dynamic motion suggested by the composition. This piece exemplifies Riley's commitment to non-representational art, focusing on the viewer's perceptual experience rather than depicting the natural world. Bagatelle 1 stands as a testament to Bridget Riley's enduring exploration of visual perception and geometric abstraction, offering viewers a captivating experience that challenges and engages the senses.
