In 1936, when Anna Mary Robertson “Grandma” Moses left her farm in Eagle Bridge, New York, she thought her life was over. Born in 1860, she’d been a housekeeper in Vermont and a farmhand in Virginia. Her husband, Thomas Moses, died in 1927. She spent her days making quilt art and embroidering pictures for friends and family. But when arthritis struck at 76, she had to find something new. One day, while making a gift for the local postman, she realized it was easier to make a painting than to bake something. She began painting scenes of rural life. At first glance, her work appears naive. Yet it brims with detail and is spatially elegant, laid out in planes. Over the next three decades, Moses completed more than 1,500 works and, by 1953, appeared on the cover of Time. This exhibition celebrates the astonishing American folk artist. —Elena Clavarino
