About this work

Bridget Riley's *Movement* series from 1962, characterized by its dizzying, kaleidoscopic patterns, marks a pivotal moment in her exploration of geometric abstraction. These two defining screen prints, considered groundbreaking upon their creation, employ simple, monochromatic shapes to create an illusion of intense motion. Despite their two-dimensionality, the rhythmic arrangement of forms gives rise to a powerful, disorienting effect, as the shapes seem to pulse and shift on the flat surface. This series captures Riley's innovative approach to manipulating optical perception, drawing the viewer into an unsettling, almost hypnotic experience.In the *Movement* series, Riley uses precise geometric shapes to create an illusion of depth and motion, resulting in a visual tension that captivates the eye. The monochromatic palette strips away any distraction of color, sharpening the focus on the interplay of shapes and the powerful optical effects they produce. The viewer may feel an almost visceral reaction as the lines and forms seem to sway and bend, producing a sense of instability and flux. Riley’s careful arrangement of these elements speaks to her ability to harness simplicity to create profound, immersive experiences, where the viewer becomes acutely aware of the act of seeing.These two works in the *Movement* series were indeed Riley's breakthrough into abstraction, paving the way for her to delve deeper into the Op Art movement. With these pieces, Riley established herself as a pioneer in creating visual phenomena that challenge the stability of perception. The series exemplifies her skill in using repetition, alignment, and shape to transform a static medium into a dynamic experience, laying the groundwork for the explorations of color and form that would define her later career. Through the *Movement* series, Riley invites viewers into an optical journey, where movement emerges from stillness and geometric precision blurs into an almost dreamlike motion.

About Bridget Riley

Bridget Riley

Life and Practice

Bridget Riley (b. 1931, Norwood, London) is one of the foremost figures in twentieth-century abstract painting, internationally celebrated as a pioneer of Op Art. Educated at Goldsmiths College and the Royal College of Art, Riley spent time teaching before dedicating herself fully to painting in the early 1960s. Her early work — strict geometric compositions in black and white that induce powerful perceptual effects of motion, vibration, and depth — established her as a key innovator in art's engagement with visual perception. Movement in Squares (1961) and Fall (1963) are among the most celebrated works of the period, and remain among the defining images of British postwar art.

Riley was awarded the International Prize for Painting at the 1968 Venice Biennale, cementing her international reputation. From the late 1960s, she began introducing colour into her work, working first with carefully limited Egyptian palettes and later a full range of hues, exploring stripe-based and diagonal compositions in which colour interaction becomes the primary subject. Her series including Orphean Elegy, The Seasons, and Rajasthan demonstrate the sustained rigour and beauty of this investigation. She continues to work from studios in London and Cornwall.

Two Distinct Periods

Riley's career divides into two widely recognised phases. Her black-and-white works of the early 1960s are the most immediately iconic: paintings that create genuine optical sensations in the viewer through geometric precision and perceptual ambiguity. From the late 1960s onward, her introduction of colour transformed her practice, producing works of extraordinary chromatic complexity that remain rooted in the same fundamental inquiry into how the eye perceives form and light.

Market Performance

Riley is one of Britain's most consistently collected living artists, with a robust secondary market anchored by major international auction houses. Her works regularly appear in Christie's, Sotheby's, and Bonhams sales, with significant paintings and prints achieving six-figure results. Riley's limited-edition prints — produced in close collaboration with respected publishers including Karsten Schubert and Waddington Custot — are particularly accessible entry points for new collectors, while her large-scale paintings command substantial premiums. Demand is strong across Europe, the United States, and Asia.

Museum Collections

Riley's work is held by the Tate (London), the Museum of Modern Art (New York), the British Council, the Arts Council of England, the Albright-Knox Art Gallery, the Kunstmuseum Basel, the National Gallery of Australia, and numerous other major institutions worldwide.
