Bridget Riley’s “Past into Present” combines a selection of works from the last two years with prior work to explore how the artist’s practice references the past, looking at both the art of painting itself and her own work. Open at David Zwirner’s Grafton Street location through October 2, viewers will find newer creations from her “Intervals” series and a continuation of the “Measure” paintings, which have been made using a palette of only three colors, off-orange, off-blue, and off-green, as well as work dating back to the 1960s, like Black to White Discs.
