Michelangelo first gained notice in his 20s for his sculptures of the Pietà (1499) and David (1501) and cemented his fame with the ceiling frescoes of the Sistine Chapel (1508–12). He was celebrated for his art’s complexity, physical realism, psychological tension, and thoughtful consideration of space, light, and shadow. Many writers have commented on his ability to turn stone into flesh and to imbue his painted figures with energy. Michelangelo’s talent continued to be recognized in subsequent centuries, and thus his fame has endured into the 21st century.
