What are the approximate dates associated with early, high, and late/mannerism Italian Renaissance art?

The Italian Renaissance spans the late thirteenth, early fourteenth centuries through the late sixteenth, early seventeenth centuries.
The early Renaissance was centered in Florence and is associated with the deeply influential Medici family. Their patronage began with Giovanni di Bicci de' Medici, (1360–1429), who commissioned work by Masaccio and Brunelleschi. His son Cosimo the Elder supported the work of Donatello and Fra Angelico.
The high Renaissance of the sixteenth century also flourished with the patronage of the Medici; in this period it was Lorenzo the Magnificent, patron of Sandro Botticelli, Domenico Ghirlandaio, Andrea del Verrocchio, Leonardo da Vinci and Michelangelo Buonarroti.
The late Italian Renaissance of the late sixteenth century featured artists including Cellini, Bronzino, Veronese, and Parmigianino. This Mannerist period produced paintings and sculptures with elongated faces and limbs that moved away from the realistic figurative work of the high Renaissance.
