The life of Michelangelo offers one of the most striking examples of the influence that a great man can have on his time. At the moment of his birth in the second half of the fifteenth century the serenity of Ghirlandajo and of Bramante illuminated Italian art. Florentine sculpture seemed about to languish away from an excess of grace in the delicate and meticulous art of Rossellino, Disiderio, Mino da Fiesole, Agostino di Duccio, Benedetto da Maiano and Andrea Sansovino. Michelangelo burst like a thunder-storm into the heavy, overcharged sky of Florence. Michelangelo di Lodovico Buonarroti Simoni or more commonly known by his first name Michelangelo (6 March 1475 - 18 February 1564) 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.[1] Considered by some the greatest living artist during his lifetime, he has since been described as one of the greatest artists of all time.[1] 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.[1] 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. Despite holding a low opinion of painting, he also created two of the most influential frescoes in the history of Western art: the scenes from Genesis on the ceiling of the Sistine Chapel in Rome, and The Last Judgment on its altar wall. His design of the Laurentian Library pioneered Mannerist architecture.[2] At the age of 74, he succeeded Antonio da Sangallo the Younger as the architect of St. Peter's Basilica. He transformed the plan so that the western end was finished to his design, as was the dome, with some modification, after his death. Michelangelo was the first Western artist whose biography was published while he was alive.[1] In fact, two biographies were published during his lifetime. One of them, by Giorgio Vasari, proposed that Michelangelo's work transcended that of any artist living or dead, and was "supreme in not one art alone but in all three".[3] In his lifetime, Michelangelo was often called Il Divino ("the divine one").[4] His contemporaries often admired his terribilità-his ability to instil a sense of awe. Attempts by subsequent artists to imitate[5] Michelangelo's impassioned, highly personal style resulted in Mannerism, the next major movement in Western art after the High Renaissance. Michelangelo, with Leonardo da Vinci and Raphael, is one of the three giants of the Florentine High Renaissance. Although their names are often cited together, Michelangelo was younger than Leonardo by 23 years, and older than Raphael by eight. Because of his reclusive nature, he had little to do with either artist and outlived both of them by more than forty years. Michelangelo took few sculpture students. He employed Francesco Granacci, who was his fellow pupil at the Medici Academy, and became one of several assistants on the Sistine Chapel ceiling.[40] Michelangelo appears to have used assistants mainly for the more manual tasks of preparing surfaces and grinding colours. Despite this, his works were to have a great influence on painters, sculptors and architects for many generations to come. While Michelangelo's David is the most famous male nude of all time and destined to be reproduced in order to grace cities around the world, some of his other works have had perhaps even greater impact on the course of art.
