Michelangelo di Lodovico Buonarroti Simoni (* 6 March 1475 – † 18 February 1564), commonly known as Michelangelo, was an Italian Renaissance sculptor, painter, architect, poet, and engineer who exerted an unparalleled influence on the development of Western art. Michelangelo was considered the greatest living artist in his lifetime, and ever since then he has been held to be one of the greatest artists of all time. A number of his works in painting, sculpture, and architecture rank among the most famous in existence. Two of his best-known works, the Pietà and David, were sculpted before he turned thirty. Michelangelo also created two of the most influential works in fresco in the history of Western art: the scenes from Genesis on the ceiling and The Last Judgment on the altar wall of the Sistine Chapel in Rome. In a demonstration of Michelangelo's unique standing, he was the first Western artist whose biography was published while he was alive.
