Michelangelo di Lodovico Buonarroti Simoni, known simply as 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. 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 and elder contemporay, Leonardo da Vinci. Several scholars have described Michelangelo as the greatest artist of his age and even as the greatest artist of all time.
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.
