Michelangelo di Lodovico Buonarroti Simoni known simply as Michelengelo , was an Italian sculptor, painter, architect and poet of the High Renaissance. Born in the Republic of Florence, his work had a major influence on the development of Western art, particularly in relation to the Renaissance notions of humanism and naturalism. He is often considered a contender for the title of the archetypal Renaissance man, along with his rival and elder contemporary, Leonardo da Vinci.Given the sheer volume of surviving correspondence, sketches, and reminiscences, Michelangelo is one of the best-documented artists of the 16th century and several scholars have described Michelangelo as the most accomplished artist of his era.

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. At the age of 71, 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. 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."

In his lifetime, Michelangelo was often called Il Divino ("the divine one").His contemporaries often admired his terribilità—his ability to instil a sense of awe in viewers of his art. Attempts by subsequent artists to imitate Michelangelo's impassioned, highly personal style contributed to the rise of Mannerism, a short-lived style and period in Western art following 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.[citation needed] 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. 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 now graces cities around the world, some of his other works have had perhaps even greater impact on the course of art. The twisting forms and tensions of the Victory, the Bruges Madonna and the Medici Madonna make them the heralds of the Mannerist art. The unfinished giants for the tomb of Pope Julius II had profound effect on late-19th- and 20th-century sculptors such as Rodin and Henry Moore.

Michelangelo's foyer of the Laurentian Library was one of the earliest buildings to utilise Classical forms in a plastic and expressive manner. This dynamic quality was later to find its major expression in Michelangelo's centrally planned St Peter's, with its giant order, its rippling cornice and its upward-launching pointed dome. The dome of St Peter's was to influence the building of churches for many centuries, including Sant'Andrea della Valle in Rome and St Paul's Cathedral, London, as well as the civic domes of many public buildings and the state capitals across America.

Artists who were directly influenced by Michelangelo include Raphael, whose monumental treatment of the figure in the School of Athens and The Expulsion of Heliodorus from the Temple owes much to Michelangelo, and whose fresco of Isaiah in Sant'Agostino closely imitates the older master's prophets. Other artists, such as Pontormo, drew on the writhing forms of the Last Judgment and the frescoes of the Capella Paolina.

The Sistine Chapel ceiling was a work of unprecedented grandeur, both for its architectonic forms, to be imitated by many Baroque ceiling painters, and also for the wealth of its inventiveness in the study of figures. Vasari wrote:

The work has proved a veritable beacon to our art, of inestimable benefit to all painters, restoring light to a world that for centuries had been plunged into darkness. Indeed, painters no longer need to seek for new inventions, novel attitudes, clothed figures, fresh ways of expression, different arrangements, or sublime subjects, for this work contains every perfection possible un
