Michelangelo di Lodovico Buonarroti Simoni or more commonly known by his first name Michelangelo was an Italian sculptor, painter, architect and poet of the High Renaissance born in the Republic of Florence, who exerted an unparalleled influence on the development of Western art. Considered by some the greatest living artist during his lifetime, he has since been described as one of the greatest artists of all time. Despite making few forays beyond the arts, his artistic versatility was of such a high order that he is often considered a contender for the title of the archetypal Renaissance man, along with his rival, the fellow Florentine and client of the Medici, Leonardo da Vinci.
A number of Michelangelo's works of painting, sculpture and architecture rank among the most famous in existence. His output in these fields was prodigious; given the sheer volume of surviving correspondence, sketches and reminiscences, he is the best-documented artist of the 16th century. He sculpted two of his best-known works, the Pietà and David, before the age of thirty.
