If the average gallery-goer spends just 27 seconds in front of an artwork, then Pierre Bonnard (1867–1947) is the antidote to a short attention span. Often invoked by today’s “slow art” movement, which encourages sustained looking, his masterful use of luminous, scumbled color and the intimate nature of his subjects reward the viewer with numerous layers of texture and meaning. In one of Bonnard’s most well-known paintings, Dining Room in the Country (1913), the eye is drawn to the figure of his wife, Marthe de Méligny, leaning on the windowsill in a crimson dress. But let the gaze wander and other details emerge—a swathe of delicate lace curtain, ghostly cats on chairs, fallen petals at the base of a jug, and outside in the garden, barely visible, a woman picking flowers.
