The Early Renaissance style was started by Masaccio and then further developed by Fra Angelico, Paolo Uccello, Piero della Francesca, Sandro Botticelli, Verrocchio, Domenico Ghirlandaio and Giovanni Bellini. The High Renaissance period was that of Leonardo da Vinci, Michelangelo, Raphael, Andrea del Sarto, Coreggio, Giorgione, the latter works of Giovanni Bellini, and Titian. The Mannerist period, dealt with in a separate article, included the latter works of Michelangelo, as well as Pontormo, Parmigianino, Bronzino and Tintoretto.
