The cinquecento period from 1500-1527 in Italy is known as the High Renaissance. During this time, the centers of art and culture shifted from Florence to Rome and Venice. High Renaissance art is characterized by its aspirations of forming a canonical classicism through architectural designs and compositions focused on figures like Plato and Aristotle that exemplified ideals of balance, harmony and rational thought. Key works included Leonardo da Vinci's Virgin of the Rocks and Raphael's School of Athens and Sistine Chapel ceiling.
