Step-by-step explanation:
The High Renaissance in Italy is associated with three pivotal artists: Leonardo da Vinci, Michelangelo, and Raphael. These masters are celebrated for their significant contributions to art during this period, which epitomized the Renaissance movement's ideals of harmony, beauty, and a naturalistic representation of figures. Among their most famous works are da Vinci's Mona Lisa and Last Supper, Michelangelo's Sistine Chapel Ceiling, and Raphael's The School of Athens. The High Renaissance was followed by the Mannerist movement, which deviated from the harmonious and proportionate style of the earlier works.
