Photos: The passion, politics and painting of Frida and Diego The story of celebrated Mexican artists Frida Kahlo and Diego Rivera is often told in terms of a couple deeply at odds, personally and artistically. She was diminutive and frail, a tortured, self-taught artist who left behind a small yet deeply personal body of work. He was large and bombastic, the "great Mexican muralist" whose frescoes and murals of peasant life and historical scenes still adorn public spaces in Mexico and the United States. But a new exhibit at Atlanta's High Museum featuring work by the couple aims to capture their shared passion for politics, Mexico and each other, despite a tumultuous relationship.
