Michelangelo di Lodovico Buonarroti Simoni exercised a huge influence on the development of Western art. He is considered a nominee for the title of the archetypal Renaissance man, along with Leonardo da Vinci. Michelangelo was the first Western artist whose biography was published while he was alive. Giorgio Vasari proposed that he was the high point of all artistic achievement of the Renaissance. In this way Michelangelo, indirectly, marked the beginning of the next major movement in Western art - that of Mannerism.A sculptor, architect, painter, and graphic artist, Michelangelo cannot be assigned definitely to any of those genres. The drawing as a medium for developing new ideas and conveying artistic thoughts, however, is the connecting link to and the basis of all his creative activities. During the Renaissance, drawing was established as the basis of every genre of art. Michelangelo viewed his drawings as material he needed for his work. Contemporaries of Michelangelo collected his drawings during his lifetime and guarded them like precious gems.
